We built Memfect because research notes vanish into folders nobody opens again. Memfect is a local-first AI tool that turns papers, PDFs, YouTube lectures, and GitHub repos into a living knowledge graph — all on your machine. No account. No subscription. No cloud. Drop in a source → AI builds atomic notes and links them to your atlas → semantic search answers questions from your own knowledge — not the internet. Works with OpenAI, Gemini, Claude, or fully local via Ollama.
