Karpathy posted his "LLM knowledge base" setup and 100k+ people saved it. Almost nobody built it. So I built a simpler, local version in Claude Cowork that files your notes, answers from your own stuff, and once a month audits and cleans itself. No code, no Obsidian, no database. - Three folders, one file. raw (your messy inbox), wiki (AI writes it, you never touch it), outputs (answers + reports), plus a CLAUDE.md rulebook that makes Claude your librarian. - One prompt builds the wiki. Claude reads everything in raw, finds the topics, writes a plain-English page each, links them, and indexes it. No RAG needed at this size. - Answers cite sources and save themselves. Ask a question, it pulls the exact pages, tells you which it used, and files the answer in outputs so the brain compounds. - The monthly check-up is the point. It hunts contradictions, unsourced claims, and gaps, web-searches to fact-check, and shows a report before changing anything. Save it as a Skill, put it on a timer, done. 📎 Full Second Brain guide PDF pinned below — every prompt, the exact CLAUDE.md rules, and the monthly audit skill. This is the kind of build we run inside The AI Accelerator (free, 19k+ members). Come grab the prompts and share your setup. 👉 What would you point your second brain at first — AI, your clients, or something else? [Watch the video here ▶️]

So I noticed most of the time sales is the same repetitive task done again and again. Like data scraping or buying it from a reputable source. Then data validation, like email verification and checking if the website and the client you got are high quality or low quality, and then filtering out the low quality and invalid. And then reaching out to the client through the most viable channel like LinkedIn, WhatsApp, and email. Previously the software didn't communicate with each other or didn't connect with each other at all, but now because of AI, we are at the point where AI can make simple decisions on our behalf, and we can be involved in deep decisions, like actually chatting with the client who is interested in our product and services. I have a technical background, and I am a 3D artist, so because of this, I managed to automate 80% of my sales process. Now I only do meetings and close the deal. I'm operating at a large scale, like sending 60,000 emails per month and sending 1,500 personalized WhatsApp messages and 400 messages on LinkedIn. I strongly believe that in the future there will be a lot of one-man companies and in thousands and thousands of dollars.

The clock ran out, the board is locked, and we've got our champion. 🔥 👑 Congratulations to Nishit Rathod — finishing #1 with a massive +57 and locking in FREE Lifetime AIA+ Membership. That's full access to AI Accelerator+ for life. No fees, ever. You're in for good, Nishit. You earned every bit of it. 🙌 And here's what made it real — Nishit didn't win by luck. He showed up, shared, and helped. Day after day. That's the whole game. Massive shout-out to everyone who battled for the top spots this month: 🥈 Surya Banthia — +33 🥉 Andrea Lopez — +20 4️⃣ Asad Patel — +17 5️⃣ Abhinav Jaiswal — +14 Every one of you moved the community forward — and we're rolling out rewards for #2 and #3 soon, so that effort is about to pay off even more. 👀 Here's the takeaway for everyone watching: the leaderboard resets, but the habits don't. The people at the top aren't doing anything you can't do. They just keep showing up. 🔄 New month, new board, new shot. The race starts NOW. Drop a 🎉 to congratulate Nishit — and a 🚀 if you're going for #1 this month. Let's go. 💪

I've been tracking this across half a dozen posts. The Mythos saga is reaching its finale, and the receipts are stacking up fast 👇 The news: Anthropic is planning to release a public version of Mythos — reportedly named Claude Fable 5 — as soon as today (June 9th). This isn't just leak-account hype anymore. Alex Heath at Sources — a credible, established reporter — is now reporting the timeline directly. New checkpoints (Claude Fable 5 and Claude Fruitcake EAP) were caught in testing over the weekend. And Anthropic is hosting its developer event in Tokyo today. The timing isn't a coincidence. Quick catch-up if you're new to the saga: Mythos is the frontier model Anthropic refused to release because it was too capable — it found 10,000+ critical vulnerabilities in its first month, across every major OS and browser. It's been locked behind Project Glasswing this whole time. What the public version reportedly is: → Same underlying Mythos-class model, but with substantially stronger guardrails → NOT as cyber-permissive as what the locked Glasswing partners can access (the offensive-security edge gets dialed back for public safety) → Dramatically better at long-horizon, multi-turn tasks — this is the part that matters most for builders The catch: early reports point to strict data retention requirements as a condition of access — likely for auditability, so they can track how the capability gets used. Worth knowing before you build on it. My take on why this is the moment: The "long-horizon, multi-turn" line is the whole story for us. We're not just getting a smarter chatbot — we're getting a model built to hold a complex task together across many steps without falling apart. That's the exact thing that's been capping what AI agents can reliably do end-to-end. If this delivers, the ceiling on what one agent can carry in your business jumps overnight. The workflows that needed three orchestrated agents and constant babysitting last month might become one Fable agent that just... finishes the job.

I set up Claude Cowork as a "Data Entry Clerk" — drag in a stack of invoices and receipts, say "log all of these," and it fills in your spreadsheet automatically. Vendor, amount, date, category. Zero typing. 60 receipts logged in ~10 minutes. It even caught a $400 charge I got billed for twice.
