## What is Lumeo. Your second brain?

Thoughts in, illumination out.

You have the thought in the car, in the shower, halfway through
something else. Then it is gone. Lumeo catches it in a sentence of
speech, files it properly, and quietly connects it to everything else
you have ever told it.

Speak
Tap the orb and talk. Lumeo transcribes you, strips the ums, gives the
thought a title and tags, and files it. There is no form to fill in and
nothing to organise.

Connect
Every thought is placed near the ones it belongs with. A remark you made
in March surfaces beside the problem you are chewing on today, because
they are about the same thing.

Illuminate
Where thoughts cluster, Lumeo proposes the idea sitting between them.
Keep it and it becomes a thought of its own. Drop it and it never comes
back.

Ask your own memory
Speak a question and Lumeo answers from your own memory and nothing else. No web search, no general knowledge, no confident invention. Every answer shows the thoughts it was built from, so you can open them and check. When your notes genuinely do not cover something, it says so. That is a good answer, not a failure.

Your constellation
Every thought is a star and every connection a line of light between two of them. Clusters are the subjects you keep returning to, whether or not you knew you had them. Pan and zoom it like a map.

Who it is for
People with too many thoughts and no system for them. Founders, writers, researchers, product people, developers. You do not need to know what a knowledge graph is, own a vault, or learn markdown.

Lumeo is free to use, with a subscription for a larger monthly allowance of AI actions.
