Ultramemory turns your email, Slack, files, and screenshots into a private memory on your Mac — making everything searchable and answers your questions with citations you can check. Free, open source, fully local.
Hey Product Hunt 👋
I built Ultramemory because I was tired of the tradeoff. The tools that actually remember your work life, every email, Slack thread, file, and screenshot, are the same tools you have to hand all of it to a cloud you don't control.
So I built the opposite. Ultramemory indexes everything into one SQLite database in your home folder and answers your questions on-device. Ask it "what did we decide about X?" and you get a real answer where every claim links back to the original source. Click it and the message or file opens right there. When two sources disagree, it tells you instead of guessing.
Search works the second you install it, no AI required. Plug in a local model via Ollama and answers turn conversational, still 100% on your machine, even offline. No account, no subscription, no telemetry, and the whole thing is open source (MIT).
Free to download for Apple Silicon. I'd love your feedback on the connectors and the citation UX especially. What would make you trust a memory tool with everything? Happy to answer anything in the comments.
no cloud + no account is the right default here. the part that bites is retrieval staying fast as the local store grows past months of history — no-account makes that harder, not easier.
Fully local memory with citations is exactly the right trust posture. I’d use this less as “AI remembers everything” and more as “I can verify where every answer came from.” How are you ranking sources across files, Slack, email, and screenshots?
