Dictation software sees everything you say, so it is fair to ask who is on the other end of it. Plainsay is built and operated by a registered Polish company, and the client is open source so the privacy claims on this site can be checked rather than believed.

What we publish so you can check us
Every privacy claim on this site is the kind that is easy to make and hard to verify. These are the things we put in the open so you do not have to take our word for any of it:
The Mac client is MIT licensed. The full source is on GitHub. If Local mode uploaded your audio, it would be visible in that code, and anyone could say so publicly.
Releases are signed and notarized. Every build is signed with an Apple Developer ID and notarized by Apple, and published with its checksums.
The benchmarks are reproducible. The method and the raw result data are in the repository, so the speed and accuracy numbers can be re-run rather than trusted.
The comparisons name their sources. Our comparison page cites where each competitor claim comes from, and says plainly when a rival is the better choice.
The data flows are written down.Why on-device states exactly what leaves your Mac in each mode, including the cases where Local mode still touches the network.
The honest line
Open source is evidence, not proof. It shows what the code does; it cannot show you which binary we built. That is why releases are notarized and checksummed, and why you can build from source yourself if it matters to you.
