# Sintesi — on-device models

Mirror of the three model files downloaded by the **Sintesi** Android app
(`com.mimaapp.sintesi`) to transcribe and rewrite voice notes on the phone,
without sending recordings anywhere. The files are byte-identical copies of
the originals; they are hosted here only so the app does not depend on
someone else's repository.

Each file keeps its own license. There is no single license for the whole
repository.
