Cosminds

Turn every book, video, article, and note into ideas you keep. Cosminds distills what you read and watch into structured knowledge, organized by concept instead of by source.

Most tools store what you consume. Cosminds connects it.

How it works

  • Add a source: a book, a YouTube video, an article, a PDF, or your own notes.
  • Cosminds extracts the core claims and ideas, not a generic summary.
  • It files each idea by concept and domain, so related thinking from different sources sits together.
  • It surfaces a cross-source insight only when two or more of your sources argue the same point or contradict each other.

What makes it different

  • Cross-source insights. You see where your sources agree and where they clash, across your whole library.
  • A grounded AI Wiki. Ask a question and get an answer built only from what you have saved, with citations. It refuses topics you have not covered, so it never makes things up.
  • Active recall. Each idea becomes a short drill that ends in writing it from memory, graded by AI, then scheduled for spaced review.
  • EU-only AI. Everything runs on Anthropic Claude through AWS Bedrock in EU regions. Your content never leaves the EU.

Who it is for

People who read and watch more than they can remember: learners, students, researchers, writers, and founders.

Free to start, no card required. Paid plans add depth, larger inputs, and more forges each week.

A startup from Krakow, Poland that is founded by Wojciech Sado.

Features & Specs

  1. Multi-source capture

    Forge books, YouTube videos, articles, PDFs, and your own notes into structured knowledge.

  2. Organized by concept

    Knowledge is grouped by idea and domain, not filed under the source it came from.

  3. Cross-source insights

    Surfaces a connection only when two or more sources argue the same point, or contradict each other.

  4. Grounded AI Wiki

    Answers questions from your own library only, with citations. It refuses topics you have not covered.

  5. Active recall and review

    A three-round drill ends in writing the idea from memory, graded by AI, then scheduled for spaced review.

  6. EU-only AI

    All AI runs on Anthropic Claude via AWS Bedrock in EU regions. Your content never leaves the EU. Each is true today, names the mechanism, and would not survive a competitor pasting it (the cross-source rule, the Wiki refusal, and EU-only are specific to you). If the directory caps description length and one gets cut, the two safest to drop are Active recall and EU-only; the first four carry the product.

Questions & Answers

As answered by people managing Cosminds.

  1. How would you describe the primary audience of Cosminds?

    People who read and watch more than they can remember. Lifelong learners, students, researchers, writers, and founders who take in books, long videos, and articles faster than notes or memory can keep up. The common thread is volume: enough incoming material that manual note-taking stops working.

  2. What makes Cosminds unique?

    Cosminds does not just store what you read, it connects it. An insight is created only when two or more of your sources argue the same point or contradict each other, so you see agreement and conflict across everything you have learned. Knowledge is organized by concept and domain, not by the source it came from. The built-in AI Wiki answers only from your own library, cites what it used, and refuses topics you have not covered, so it never invents an answer.

  3. Why should a person choose Cosminds over its competitors?

    Tools like Obsidian make you file and link everything by hand. Flashcard tools like Anki make you write every card yourself. Capture tools summarize one source and stop there. Cosminds does the extraction, the cross-source connection, and the recall for you. It reads across your whole library, shows where sources agree or clash, answers questions only from what you saved, and turns each idea into a written recall test that an AI grades. You keep the thinking, it removes the filing.

  4. What's the story behind Cosminds?

    I read and watched a lot and kept almost none of it. Highlights piled up in apps I never reopened, and notes turned into a graveyard. I built Cosminds to fix my own problem: one place where everything I take in gets distilled into ideas, connected across sources, and tested until it sticks. It is built by one person and shaped by daily use as a real reader, not a demo.

  5. Which are the primary technologies used for building Cosminds?

    Frontend: React, Vite, and TypeScript. Backend: Python and FastAPI on AWS Lambda and API Gateway, with DynamoDB, S3, and Cognito. AI runs on Anthropic Claude and Amazon Titan embeddings through AWS Bedrock, in EU regions only. Payments through Stripe.
