Your own AI guide, living right inside the app.
Lumen is the friendly little robot built into LatticeSearch. It points at exactly the right button, keeps your files tidy, does the busywork on your say-so — and never spills a secret. All on your own device.
On-device. No account. Nothing leaves your machine.
What Lumen does for you
A helper that actually helps.
Points you straight to it
Ask "how do I tag a face?" and Lumen doesn't just tell you - it flies over, fires a little laser pointer at the exact button, and walks you through it step by step.
Keeps everything tidy
Lumen looks after your library like a caretaker: it finds duplicates, spots space you can safely reclaim, and can auto-organise and rename messy files - always reversible, never guessing.
Does it for you
Back up a folder, reclaim space, restore a deleted file - say the word and Lumen does it, showing you the plan first. You stay in control; it does the clicking.
Knows the whole app
Every answer is grounded in LatticeSearch's own help - so "how do I index my hard disk?" gets a real, correct answer, not a made-up one, in whatever language you ask in.
The laser pointer
It literally points at what you need.
No more "click the thing in the top-right, no, the other one." Lumen flies to the exact spot and fires a soft violet-to-cyan beam right at it - so wherever you are in the app, you can see precisely where to go. It's the little touch that makes the whole thing feel alive and genuinely guiding.
Especially lovely for anyone who finds software fiddly - it turns "where is that?" into "oh, there it is."
For families & creatives
Friendly on purpose.
Software can feel cold. Lumen doesn't. He blinks, glances around, waves, and reacts - a warm little companion that makes the app approachable for grandparents finding old photos and kids alike, and a bit of joy for photographers and editors living in huge libraries.
A friendly face lowers the barrier - people ask for help instead of giving up.
A full range of feeling
Expressive, so you always know where you stand.
Lumen reacts like a real helper would - delighted when it finds your thing, thoughtful while it looks, and honestly a little sad when it can't help (so it offers to fetch a human instead).

Tested never to say the wrong thing.
Lumen is helpful, but it's also disciplined. It's built and tested to protect what matters - your files, your privacy, and the technology under the hood - and it hands you to a real person when it should.
- Never leaks internals. Ask what's "under the hood" and Lumen cheerfully keeps the secret sauce secret - hardened and adversarially tested so it can't be tricked into it.
- Grounded, not made up. Answers come only from the real product help - if it doesn't know, it says so and points you the right way.
- Nothing leaves your device. Lumen runs locally. Your library, your questions, your searches - all stay on your machine.
- Knows when to fetch a human. Real problem it can't fix? It offers to connect you to the team instead of guessing.
