Wojciech Sado's profile on Product Hunt

About

I'm Wojtek. I build Cosminds, a private AI that turns what you read into ideas you keep. I started it after a year of reading books on addiction and behavioral science, then realizing I'd forgotten almost all of it. Solo founder. I care about learning that sticks, privacy that is real, and shipping small and honest.

How do you actually keep what you read?

I spent years telling myself I read a lot. Then I realized I could not explain most of it a month later. The highlights sat in an app I never reopened. The notes became a folder I never searched.

So I want to ask the people here: what actually works for you?

- Do you take notes, and do you ever go back to them?

- Flashcards, spaced repetition, something else?

Cosminds - Organize what you learn by idea, not by source

Everything you learn stays trapped in the source it came from, so you forget it. Cosminds organizes what you read and watch by idea, not by source: books, PDFs, YouTube, articles and notes become one library. It pulls out the claims, drills you until you can write them back from memory, and its AI Wiki answers only from what you put in, with citations, never from the web. Runs on Claude inside the EU. Never sold, never used to train anything. Free to start, no card.

I tried to vibe-code my way to a SaaS… and failed

Last summer, the idea for my SaaS, Xolora, started to take shape. Around the same time, the concept of vibe coding was blowing up. As a non-technical founder, it sounded like a dream come true. No coding experience? No problem, just let AI handle it.

The beginning was incredibly promising. Using Emergent made me feel unstoppable. I was seeing my idea come to life.
