Opyt turns the people and topics you already follow into a knowledge base. Point it at your X bookmarks, Substack subscriptions, blogs, GitHub repos or arXiv papers, and it pulls in their archives. It reads a topic through, writes its own follow-up questions, and keeps looking for new work that builds on what you've collected. Share what your knowledge base, keep exploring, and let your AI read it all. Free, MIT licensed, and your knowledge base can stay local.
I kept bookmarking posts on X, subscribing to Substacks, and saving papers I meant to read. Most of them stayed unread. I wanted to use that material where I actually work and learn: Claude.
So I built Opyt. It turns the sources you already follow and trust into a knowledge base and keeps adding to it as they publish. You can ask questions about all of it from Claude, Cursor, Codex, or any MCP-compatible client.
Here’s how I use it: - Catch up on AI. Ask what’s new and get an answer drawn from people you follow and trust, plus research and repos Opyt found in the background. - Check before building. Search repos, papers, and posts together. Find out whether someone already built your idea and what others learned trying it. - Think through career decisions. Explore which industry you might want to work in, drawing on what your sources see growing, slowing down, or changing and where they disagree. - Share with a friend. Give each other access to your knowledge bases. Search both with one question, see whose collection each result came from, and revoke access whenever you want.
No new app to open. Opyt is free and MIT licensed, and you can keep your knowledge base local. You pay for the AI tools you use and any OpenRouter usage.

Who hunted Opyt?
Opyt was hunted by David Maimon . A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
