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.

Hey everyone! Maker here 👋🏼 Memfect started as a personal frustration. I kept reading papers and forgetting them. I tried every note app out there — Obsidian, Notion, Roam — but the AI features were either bolted-on or required sending all my data to a server. So I built something local-first from day one, where the AI does the heavy lifting (synthesis, linking, search) but your data never leaves your machine unless you want it to. The feature I’m most proud of: the literature radar. You set a watch query, and Memfect automatically scans arXiv and ranks new papers by how relevant they are to your existing atlas. It’s like having a research assistant that reads the frontier for you. Would love to hear what you think — especially from PKM nerds, researchers, and anyone who’s ever wished their notes actually talked to each other. 🙏

How does the knowledge graph actually look when you drop in a mix of PDFs and YouTube links, do the atomic notes get visually clustered or is it more of a flat list?

How does the knowledge graph actually stay useful as the number of sources grows — do the atomic notes get refactored automatically or is that manual cleanup on me?
