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.
