Lychnari

Knowledge that works offline.

Ask anything.

Type a question, say it out loud, or show it a photo or a document. Lychnari answers from what is stored on your phone, so it keeps working in the mountains, at sea, or when the network is down.

An answer about drying meat, with its Wikipedia and survival-manual passages listed underneath

No signal.
No internet.

It all runs on your phone.

The model and the library live on the device. The app doesn’t ask for internet access, has no account and no tracking, and nothing you ask leaves the phone.

Good to know

What’s inside: Wikipedia articles and public-domain survival guides, stored on the phone with a small AI model that reads them for you.
How sure it is: Answers come from a small model and can be wrong. The sources are always there to check.
What it isn’t: Lychnari gives general information. It is not a medical service and not an emergency service. In an emergency, call 112.
Your data: Lychnari collects nothing. Read the privacy page.

Coming soon.
