Cerebro
You missed a miracle while you slept. Between midnight and breakfast people uploaded five hundred hours of video every single minute. That is seven hundred and twenty thousand fresh hours in one day, enough footage to keep you watching until 2107 if you pressed play right now. And that is only YouTube. IDC says humanity will push out about 463 exabytes of new data every day in 2025. Stack that on hard drives and the column reaches the Moon and comes halfway back. Insane right? it get's worst. McKinsey finds that knowledge workers already burn a full work-day each week just hunting for…

What it does
Cerebro, the revolutionary knowledge management tool. Seamlessly organize, connect, and amplify your ideas like never before.
Elevate your thinking with Cerebro, the revolutionary knowledge management tool. Seamlessly organize, connect, and amplify your ideas like never before.
Every day, you miss crucial insights buried in your videos, articles, and books. You watch. You read. You listen. But 90% slips away because there's just too much to remember. Let's be honest - you barely have time to consume the information, let alone take notes. Then that moment hits: 'I know I saw it somewhere...' turns into an hour lost searching through tabs and folders. Each buried insight is a missed chance to level up your work, boost your income, or beat your competition. Turn videos, articles, and books into searchable, and actionable knowledge. See a useful video or blog? Just paste the link. Have a PDF? Simply add it in. That's it. Need to find something? Just ask in plain…from heycerebro.com

Build a personal knowledge graph from the content you consume online2023 · recall.wiki · ▲79I've been working on this tool that lets you build a personal knowledge graph from articles, blog posts, podcasts, YouTube videos, and other content you find interesting online. You can safely forget everything and trust that Recall will resurface it when something new that is related comes up. Looking forward to your thoughts and feedback on how it could be improved! The original version of Recall was posted last year nov on HN: https://news.ycombinator.com/item?id=33425947 Since then I have pivoted to a browser extension.
- IMI'm a non-hacker "idea guy" and my weekend project took 1,670 + days2012 · readwriteweb.com · ▲21
I am a non-hacker "idea guy" with zero discernible talent. Like most, the story starts with me doing things the hard way. I dreamt of a tool that would save me countless hours. Like most of my ideas, it was supposed to die in a couple of hours, but this one had some legs.... "If I needed this, surely others did too" kept looping in my head. Could I get this built? Could I build it myself? Nah...too lazy to learn how, but before I did anything, I had to promise myself one thing: No more ideas! If ideas were sit-ups, I would have a six pack instead of this tire. It was a constant mental…
Zine2025 · zine.ai · ▲26I spent 8 weeks building Zine, an AI-powered search app for your team's knowledge, entirely solo. No team, no extra funding. Just me, AI coding tools, and the platform I had already built. Instead of building infrastructure (connectors, vector DBs, transcription, entity extraction, etc.), I reused Graphlit, the same stack our customers use. That saved about 4-5 months of backend work and let me focus 100 percent on product and UX. The result: I built and shipped an MVP in 8 weeks, got the first paying customer in 4 months, used 30+ data connectors with real-time sync and entity-aware…

Right now it's a Nicotine patch for brain rot/doom scrolling. You still get the scroll, but with more meaningful content. WHERE I WANT IT TO GO: Users mark what they are interested in (e.g. AI, or Space or Whatever), and it should crawl the latest scientific articles, high quality YouTube videos, pods, present it in a format that fits you, in a nice feed. NOW: You can search for anything (e.g. "Sea Explorers" --> The app crawls Wikipedia or YouTube and pulls together a short feed (e.g. Columbus, Vasco da Gama etc.,). I'm using RAG so that I always can reference the original data source…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
