I'm a marketer, not a developer — but I've shipped more working software in the last year than in the previous twenty. This is what vibe coding actually looks like in practice: live products, real users, real revenue, real edge cases.
Get an email when a new project ships — plus the occasional dispatch from across the High Caliber AI network. No spam. Unsubscribe anytime.
What are you into? Pick one and I'll surface the projects most likely to be useful — across marketing, community, self-help, cooking, PR, job hunting, BD/sales, or SEO.
Marketing tools, AI-native SaaS, community platforms, and one infamous calling card. The stuff that buys the groceries — and rewires how marketing gets done.
Pressure-test product concepts on real-feeling humans.
An AI research panel that thinks, disagrees, and reacts like your customers. Spin up 200+ richly profiled synthetic respondents and go from brief to insights in under 60 seconds — without recruiting, scheduling, or a six-week wait.
Live AI debates. Watch personas battle it out — then vote for the winner.
A real-time synthetic debate engine where AI personas with distinct personalities, expertise, and preferred models argue a topic you choose. Free roundtable mode for guests. Full deliberation with custom personas, vote tallies, and shareable verdict cards for PanelSynth Pro. Proof that AI research can be entertaining, not just functional.
The marketing industry's running record of who called what.
A celebratory public archive of predictions made by marketing pundits, analysts, and press — paired with the follow-up evidence of what actually happened. Generous-but-honest verdicts ('called it,' 'partially right,' 'still evolving'), AI-powered discovery and scoring, and a thermal-printer receipt-paper aesthetic taken full-throttle.
Receipts on what AI says about your brand.
A generative engine reputation platform that audits ChatGPT, Gemini, and Perplexity Sonar across dozens of buyer-intent prompts per topic. Captures every cited URL and snippet, scores visibility and sentiment vs. competitors, and hands you a tactical fix list — at a scale no human team can match. Weekly auto-runs.
The wire is dead. The agent is the audience.
A manifesto, schema spec, glossary, and live grader for press releases written for AI agents — not journalists. Paste a release and get a machine-readability score with concrete fixes: JSON-LD coverage, atomic facts, citeable quotes, and structured boilerplate. Built to define how PR adapts to a world where ~70% of news queries get answered by LLMs.
AI Summary Optimization (ASO) — own the 1-sentence preview.
Apple Intelligence and Gmail Gemini collapse emails into 1-2 sentences before a human ever sees them. The Glance is the first platform built for that surface: side-by-side Apple/Gmail/Outlook summary previews, persona-driven recall scoring, a 0-100 Summary Score, A/B lab, and subject line predictor. Built so marketers can win the glance — not just the open.
The greatest ads, landing pages, and emails — hacked open, trick by trick.
A magician's-theater-styled teardown library that deconstructs real campaigns into the specific tricks that make them work. White / grey / black-magic ratings, a tricks encyclopedia, and submissions from readers. Built so marketers can perform the trick themselves — and recognize when it's being performed on them.
The teardown engine for sales — cold emails, decks, demos, discovery, hacked open.
Sister site to Marketing Hacked, same teardown DNA aimed squarely at revenue teams. Real cold emails, pitch decks, demo flows, cadences, and discovery scripts deconstructed trick-by-trick with white / grey / black-magic ratings, a tactics encyclopedia, and reader submissions. Built so founders, AEs, and RevOps can perform the move themselves — and recognize when it's being run on them.
AI Optimization, hacked open — the tricks behind getting cited by ChatGPT, Gemini, and Perplexity.
Sister site to Marketing Hacked, aimed at the AIO / GEO operator. Real prompts, real citations, real teardowns of how brands win (and lose) the AI answer layer. White / grey / black-magic ratings, a tactics encyclopedia, and reader submissions. Built so marketers can perform the move themselves — and recognize when someone else is performing it on them.
The tricks behind PR campaigns that actually moved the needle — hacked open.
Same teardown DNA as Marketing Hacked, aimed at comms and PR. Real press hits, embargoes, founder narratives, exclusives, and brand stunts deconstructed trick-by-trick with white / grey / black-magic ratings. Built so PR pros and founders can perform the move themselves — and spot when someone's spinning them.
The tricks behind the SERPs — hacked open trick by trick.
Sister site to Marketing Hacked for the SEO operator. Real ranking pages, real link plays, real schema and content patterns deconstructed with white / grey / black-magic ratings, a tactics encyclopedia, and reader submissions. Built so SEOs can study the move — and call out the spammy ones.
Deconstructing viral content patterns into executable blueprints.
Sister site to Marketing Hacked, same teardown DNA aimed at content engines and growth mechanics. Real high-growth content plays — from changelogs to transparency stunts to brand spectacles — deconstructed into the specific patterns that made them work. White / grey / black-magic ratings, a tactics encyclopedia, and reader submissions. Built so content operators can steal the play tomorrow.
A dignified place to honor a community's legacy.
Professional communities — alumni networks, industry groups, fraternal orders — get a dedicated, dignified memorial space to remember departed members. Rich tribute pages, admin moderation, member contributions.
A wiki for your community's conversations.
Forward an email thread or paste it in. Communipedia organizes it into a private, searchable archive of summaries, topics, people, and recommended links — for an approved-members-only community.
A modern Slack companion for community owners — welcome the new, reach the active.
Multi-step welcome DM sequences for new Slack joiners (day 0, day 3, day 14 — your call), plus an active-member finder that surfaces who actually posted in a channel in the last 30/60/90 days so owners can DM the right people. Multi-workspace, audit logs, opt-out aware. Built so community operators stop guessing who's alive in their Slack.
Yes, we share a name. No, I've never been to prison. Yes, this is my actual calling card.
Twenty years of sharing a name with the Son of Sam, channeled into the most memorable business card a marketer could ask for. Side-by-side comparison, a 'which David is which' quiz, press features (NYT, Washington Post, Letterman bits), and the long-running playbook for turning a brand-collision problem into a permanent conversation starter. People meet me, find this site, and never forget the name. That's the whole point.
Be found by AI when recruiters ask who to hire.
Recruitment's new front door is a prompt. I'm Findable turns a resume into a structured, citeable profile — JSON-LD, llms.txt, Open Graph, the works — so ChatGPT, Perplexity, and Claude surface you when a recruiter asks for a senior PM in fintech pricing or a CMO who's scaled CPG D2C. Free for job seekers — always will be — with gated contact so your inbox stays yours. Pairs with the /jobs resource hub as the GEO layer for careers.
The Marketing Arcade — games that teach marketing by making you lose.
An 80s-arcade hub for marketing-themed games. The Marketing Hustle (Drug Wars, but for marketers), Slackmaster (community-triage archetype quiz), Brand Misfit (this-or-that brand voice game), and more in the cabinet. Quarter-eating fun that doubles as a strategy lesson.
The fleet control plane for Lovable apps.
One thin snippet that turns every Lovable app into a managed fleet — cross-app event inbox, identity graph stitching visitors across properties, fleet status board, remote-controlled severity/sampling, and built-in Stripe/Resend/uptime adapters. Already powering the High Caliber AI network. Now in private beta for other Lovable builders.
If you can dream it, you can build it. A home for people vibing dreams into real software.
A sister portfolio hub for the vibe-coding era — a showcase of dreams shipped as real products, with deep-dive stories on the ones that were hardest to pull off. Complements /built-with-ai by leading with the emotional through-line (why the dream mattered) and the craft (the prompts, the stack, the reversals). One marketer, one prompt at a time.
Your business development navigator. With teeth.
An AI BD copilot that turns your existing relationships into a warm-intro pipeline. Ask in plain English ('CMOs at mid-market B2C with $30M+ budgets'), the Gator surfaces who you already know in 3 hops or less, stalks every target through a sourced → warmed → intro-made kanban, and drafts forwardable intros grounded in real shared history. Part navigator, part predator.
Stop reading dashboards. Start sending the next email.
A chained marketing suite where every tool feeds the next via Suite Memory. BrandReceipts finds your wedge against AI search, PanelSynth pressure-tests it against 200 synthetic buyers, The Glance compresses the winning angle into the notification line that gets opened, and BD Gator routes it to real, enriched contacts. One workspace, not a dashboard — where the work compounds instead of starting from scratch every Monday.
Autonomous B2B campaign engine — URL → live Reddit Ads in 60 seconds.
Paste a product URL. The agent live-scrapes the site, profiles your ICP, engineers 3 conversion-optimized creatives (pain / outcome / social-proof), picks 5 hyper-specific subreddits, and ships the campaign straight to Reddit Ads via secure API. No agency, no creative review, no media buyer. $50 testing tier through $10K enterprise.
Personal-brand GEO — get cited by ChatGPT, Perplexity, and Gemini for the topics you own.
Personal-brand generative-engine optimization. Track how AI assistants describe you, the topics you're already cited for, the ones you should own next, and the exact receipts (posts, bylines, quotes) that will move the needle. Sister tool to Brand Receipts and I'm Findable — one for brands, one for job seekers, this one for people building a category-defining personal brand.
A fractional franchise network. Don't hire a team — deploy a proven builder.
A vetted network of AI-native operators executing pre-architected blueprints inside your company. Scope a sprint with the Sprint Scoper, get matched to a Node with the exact track record, and ship in weeks — embedded, documented, handed off. Operators from OpenAI, Stripe, Anthropic, Linear, Vercel, Uber, and Mailchimp. Billed by the week, governed by us, no agency markup.
The agency for vetted AI speakers — operators who've actually shipped.
A speakers bureau built for the AI era: practitioners who build, ship, and operate AI in the wild — not just talk about it. Matchmaking between event organizers and proven AI operators, with transparent topics, fees, and receipts.
The site you're on — itself a vibe-coded marvel.
200+ pages, an agentic GEO blog engine that writes and self-publishes, a 20-day AI marketing mini-course with automated email sequencing, an AI readiness voice assessment, an AI chat trained on the book, programmatic SEO niches, and a full admin hub. Every line of code shipped via Lovable.
A play, a gift-basket shop with a 12-year-old, and a Drug-Wars-for-marketers game. Vibe coding doesn't have to be serious — sometimes it's just what you do on a Sunday.
A new play. Two cousins, same name, very different destinies.
The companion site for an original stage play I wrote — a dark comedy about two cousins both named David Berkowitz who discover they're dating the same woman. Full script excerpts, character sheets, production info, and a built-in identity game.
Handcrafted gift baskets — built with my 12-year-old daughter.
A storefront for curated gift baskets, designed and shipped together with my 12-year-old daughter. Browse featured baskets, build-your-own flow, and a candy-pink brand identity she art-directed. Proof that AI builders put real software in the hands of the next generation — and that the best co-founder might be at the kitchen table.
A Talmud for recipes — one dish in the center, the canon arguing in the margins.
Each page is a single canonical dish ringed by attributed commentary from chefs, cookbook authors, food writers, and home cooks — arguing about why to stir here, salt then, skip this, never that. The center is a bare-bones template. The margins are the craft. A working draft (Edition 0.1) with ten dishes and counting.
The greatest recipes are on the box.
A scrapbook of the iconic American recipes printed on the back of bags, boxes, tins, and tubs — Rice Krispie Treats, Toll House Cookies, Hershey's Hot Cocoa, and dozens more, all in one searchable, browsable archive. Built because the best recipes in the country shouldn't live on crumpled cardboard.
Never have a bad first date in NYC again.
A first true consumer app — tailored NYC date itineraries that scale with your intimacy, from the high-stakes first drink to the all-day fourth-date excursion. Saved date profiles, four-stage method (Vetting → Spark → Dive → Trip), live weather via Open-Meteo, neighborhood-aware routing, and a graceful exit baked in.
The friction-first directory of attributed psychological micro-protocols.
Behavioral, organizational, and clinical micro-protocols — fully traceable, ready in under ten minutes. Find a pivot for perfectionism paralysis, first-time manager anxiety, difficult conversation avoidance, creeping burnout, negotiation freeze, and decision fatigue. Three traditions, one library: Behavioral (Nir Eyal, Dan Pink), Organizational (Adam Grant), and Clinical (Lori Gottlieb, Esther Perel).
Optimism is a discipline, not a mood.
Grounded hope as an operating system: clear-eyed about reality, relentless about what you can move today. Three engines (Mindset, Skill Set, Action Set), twelve traits, eight archetypes, and a diagnostic that drops you into a 72-hour blueprint built from your own answers. A sister project to TinyPivots — where TinyPivots gives you the micro-protocols, Practical Optimism gives you the outlook and operating cadence around them. The two are being integrated as one library of agency.
Forward it. Scrub it. Slam it. — a public-good scam directory.
Forward any suspicious email to report@slamthatscam.com. AI strips your PII, extracts the scam pattern, scores the risk, and publishes a public warning so the next person who Googles it finds the truth. Free forever, indexed for search, built for the public good.
A public health advisory for the age of linguistic flattening.
A satirical intervention against synthetic median voice — the slow creep of AI-polished language into human conversation. Styled as a vintage public health bulletin, it diagnoses the symptoms (predictive pausing, synonym flattening, assistant creep) and prescribes the cure: actual human friction. Proof that a single-page parody can be sharper than a thousand-word essay.
The autonomous NBA sneaker database.
Every shoe. Every player. Every night. Kick Court pulls every colorway worn on court, surfaces the story behind it, and ranks rotations by player, team, and brand — all on its own, every night. A live index of what the league actually wore, built to settle debates and fuel obsessions.
A live roster purge tracker for the Mets' 40-man trade deadline watch.
One untouchable (Juan Soto). Everyone else is fair game. This auto-updating tracker watches the Mets' 40-man roster and answers the only question that matters as the deadline approaches: did they trade everyone yet? Built as a single-purpose sports parody with a scoreboard heart.
The meta hub for the whole Event Network — one feed for every conference we cover.
The connective tissue for the Event Network: a running feed of what's happening across Cannes Lions, CES, SXSW, Possible, Ad Week NY, ShopTalk, and Davos — plus the calendar of what's next. Built for the marketer who's tired of pretending they've read every recap.
The unauthorized, beach-bleached, slightly-too-honest feed of Cannes Lions.
The Cannes Lions node of the Event Network. Party schedule with RSVP links, Croisette weather & stats, an AI bouncer that scores your photo for Cannes-coded vibes, an anonymous attendee census, and a curated soundtrack. The feed you'd actually want to read between rosé refills.
CES in Vegas, stripped down to what actually matters.
The CES node of the Event Network. What booths to skip, which keynotes to stream in your hotel robe, and the parties worth the cab across the Strip. Built for people who cover CES for a living and would rather cover it from a lounger.
SXSW dispatches, one taco at a time.
The SXSW node of the Event Network. Panel picks, breakfast-taco rankings, badge-line intel, and the party map. For Austin week attendees who want less FOMO and more queso.
The unofficial companion to Possible in Miami.
The Possible node of the Event Network. Session picks, side-events, brand parties, and a running attendee census — for the marketing crowd swapping conference-badge FOMO for beach-badge FOMO.
Ad Week NY, addled and honest.
The Advertising Week New York node of the Event Network. Sessions that are actually worth the badge, party map by day, and running receipts on the ad-industry state of the union.
ShopTalk, all the blather and none of the badges.
The ShopTalk node of the Event Network. Retail-and-commerce sessions worth catching, brand-side gossip, and the party map for the Wynn crowd. Built for the retail-tech and commerce marketing crowd.
The World Economic Forum, digested for the rest of us.
The Davos node of the Event Network. WEF sessions and side-events reduced to what actually matters, plus the running list of who said what on the mountain — for marketing and comms leaders who want the signal without the ski jacket.
Spooky. Scary. Boys becoming men, men becoming wolves.
A loving tribute to the greatest fake song in TV history — turned into a real, live cultural micro-site. Part parody, part fan shrine, part proof that humor and satire are their own emerging category inside the network.
The internet's most useful comments, sorted by how much they make you laugh.
A satirical curation of Reddit threads and forum culture — the absurd advice, the unexpectedly helpful strangers, the comment-section debates that belong in a museum. Reddit and Weep turns the front page of the internet into a comedy page.
The dating app for people who will get back to you… sometime.
A rapid-prototype parody landing page built to demonstrate high-speed AI generation, UI/UX framing, and cultural responsiveness. A creative translation of an internet-culture reference about the art of the vague plan, taken from a video concept to a live deployment in a single build session on Lovable — proof that the toolkit can ship sharp, on-brand comedy as fast as it ships enterprise UI.
Culture, faith, philosophy, and language as a testbed. These are the builds where the subject matter is niche on purpose — a rationalist prayerbook, a Yiddish dictionary for outsiders, an AI speech coach that refuses to ghostwrite, and a directory for everyone else shipping in the same lane. Small audiences, sharp constraints, fastest lessons.
Where Jewish tradition meets the philosophy of reason.
A bilingual Jewish prayer book illuminated by Baruch Spinoza's philosophical lens. Browse the full siddur, ask Spinoza in an AI chat, compare perspectives in the Spinoza Lab, or open this week's parashah.
Coding vibes from the kosher tribe.
A directory and community hub for culturally-specific vibe coding — AI-built apps, holiday hacks, prompt kits, and the people shipping them. Features a hechsher-style project directory, an AI idea generator that spits out a full name/pitch/stack/build prompt on demand, and a submission flow so other builders can list their work. The connective tissue for the experiments track.
AI as sparring partner, never ghostwriter.
A coming-of-age speech coach for teens and the parents losing sleep over their toast. Five tools that ask better questions than they answer, plus The Gatekeeper — 12 honest rulings on where AI belongs in the prep and where it absolutely doesn't. A working case study in AI that builds a kid's voice instead of replacing it.
Beyond Oy — the outsider's guide to the most expressive language on Earth.
A modern, playful Yiddish dictionary and companion for people who love the language but don't have the heritage, expertise, or perfect pronunciation. Browse 49+ words with Hebrew script, phonetics, a Mishegas Meter, and category tags. Play Nachas or Shonda, run the Yinglish Gauntlet, get paired with a word via the Matcher, and browse a curated bookshelf. No heritage required — just a willingness to plotz.
Stoicism, taken way too far. On purpose.
A humor site pushing stoic philosophy to absurd extremes — daily meditations, XTREME-branded virtues, and the sort of advice Marcus Aurelius would delete after re-reading. Not real self-help. Real funny.
Marketing, Sales, AIO, PR, SEO, and Content — each one a magician's-theater library of real campaigns, deconstructed trick by trick. White, grey, and black-magic ratings. Reader submissions. No paywalls.
Ads, landing pages & emails — hacked open, trick by trick.
Cold emails, decks, demos & discovery — hacked open.
Citations in ChatGPT, Gemini & Perplexity — hacked open.
PR campaigns that actually moved the needle — hacked open.
Ranking pages, link plays & schema moves — hacked open.
Viral content patterns — hacked open into executable blueprints.
Every project here solves a problem I personally had — a name confusion, a community grieving, a research bottleneck. Vibe coding is wasted on hypothetical problems.
I describe behavior in plain English to Lovable. The AI handles syntax, schema, and styling. I handle taste, copy, and judgment about what's actually worth shipping.
Most of these went live within a week of the first prompt. The hard work is what comes after — talking to users, fixing edges, deciding what NOT to build.
"If you can describe the product, you can ship the product. The bottleneck isn't code anymore — it's creativity, vision, and persistence."
— David Berkowitz

Not every experiment becomes a flagship. The Attic is the honest record — what was tried, what got rebranded, what got folded into something better, and what might come back when the timing is right. Shipping fast means letting some things go.
Early build
2025
2025
Have a project you remember that isn't here? Tell David — the Attic is the receipts version of the resume.
Not counted in the shipped total — on purpose. These are the concepts I tried, prototyped, or seriously scoped and walked away from. The lesson matters more than the headstone.
2025 · Did not ship
The Graveyard grows. Failure is the price of shipping — and the curriculum covers what these taught me too.
Whether it's licensing a tool, embedding one for your team, having me build one with you, or just understanding how a project came together — start the conversation here.
Tell me the project (or the problem) and what you're trying to do with it.
The questions ChatGPT, Perplexity, and humans ask most.
Vibe coding is building real software by describing the desired behavior in plain English to an AI coding tool (like Lovable) instead of writing the code line-by-line yourself. The human supplies taste, judgment, product decisions, and copy; the AI handles syntax, schema, and styling.
Yes. David Berkowitz is a marketer with no computer science degree and has shipped 54 live products in roughly a year using AI — including PanelSynth (an AI research panel platform), War Room (a live AI debate engine with synthetic personas), The AI Press Release (a manifesto and grader for AI-readable PR), We've Got Receipts (a public archive of marketing predictions and what actually happened), Engineer Marketing (a chained suite of four tools with shared Suite Memory), Content Hacked (weekly teardowns of viral content patterns), Community Condolences (a memorial platform), Siddur Spinoza (a bilingual prayer book with AI chat), Communipedia (an email-in community wiki), Sons of Sam (a stage play companion site), Not That David Berkowitz (an SEO rescue for sharing a name with the Son of Sam), TinyPivots (a directory of attributed psychological micro-protocols), The Marketing Hustle (a Drug Wars-style game for marketers), and the High Caliber AI website itself (200+ pages, agentic blog engine, voice assessment, AI mini-course).
Primarily Lovable for the front end and full-stack scaffolding, Supabase for database, auth, and edge functions, Lovable AI Gateway for LLM features, Resend for email, Stripe for payments, and ElevenLabs for voice. Most projects ship on this same stack.
Most of the projects in the Built with AI showcase went from first prompt to live URL within a week. The harder, longer work is what comes after launch — talking to users, fixing edge cases, and deciding what NOT to build.
It is when the operator has product judgment and is willing to iterate. Every project on this page is live, has real users, and several generate revenue. The bottleneck is no longer code — it's creativity, vision, and persistence.
David Berkowitz built highcaliberai.com himself using Lovable. It includes 200+ pages, an agentic GEO blog engine that writes and self-publishes, a 20-day AI marketing mini-course with automated email sequencing, a voice-based AI readiness assessment, an AI chat trained on his book, programmatic SEO niche pages, and a full admin hub.
Some are 100% free forever. Some are freemium with paid upgrades. One is a $9 nominal upgrade with a free trial. Pick your sandbox — and paying customers of PanelSynth or Brand Receipts get the AI marketing course on the house.
Active subscribers email david@highcaliberai.com with their account email — we mint a comp code and send you in.
See the courseMost AI marketing advice comes from people who've never built anything. David runs fractional CMO engagements, workshops, and keynotes — backed by 54 live products, not slides.
