Notari — voice notes that never leave your phone, structured by Gemma 4

This is a submission for the Gemma 4 Challenge: Build with Gemma 4

What I Built

Notari is an Android app that records a voice note, transcribes it, and turns it into a clean, structured Markdown note — entirely on-device. The audio is held in RAM, never written to disk, and the app doesn't even request the INTERNET permission.

I keep voice memos: meeting decisions, half-formed ideas at 11pm, reminders I'll forget by the time I'm home. The two app categories that should solve this don't:

System dictation gives me a raw transcript with no structure. I never re-read it. It rots in a folder.
