AI that thinks alongside you.
Lume builds small, sharp AI tools for people who write, research, and think for a living. No dashboards. No noise. Just better thinking.
Get early access →What we make
We're focused on three quiet tools that work the way your mind already does.
Lume Notes
An AI-native notebook that remembers context across sessions.
Lume Search
Search your documents the way you'd ask a colleague.
Lume Draft
A writing companion that edits like a thoughtful friend, not a robot.
Lume API
The same models we use, available to build with.
Privacy first. Your data is never used to train shared models. Local-first where possible.
How we work
- Small team. Long horizons. Real craftsmanship.
- We ship monthly, not quarterly.
- We measure success by how often our tools fade into the background.
- If we can't make it feel calm, we don't ship it.
Trusted by quiet teams
Researchers, writers, and product teams at small studios and large labs use Lume to think out loud — without the overhead of yet another app.
