The dictation landscape splits into two clusters that don't overlap: mature desktop apps with no mobile build, and mobile apps that are closed-source, subscription-priced, or vague about where transcription actually runs. OpenWispr is the same free, MIT-licensed, on-device app on both.
The desktop on-device dictation cluster is genuinely strong: Handy (27.7k stars, mac/Windows/Linux, no cloud path at all), FluidVoice (9.0k stars, macOS 15+ with a custom-trained local cleanup model), VoiceInk (GPL, Apple Silicon only, the best failure-recovery UX found in this research), and Muesli (Apple Silicon only, dictation plus local meeting notes). None of them ship an Android app — not in beta, not waitlisted.
The Android side looks different. Typeless reaches Android with a real IME keyboard, but it's closed source and $12–30/month past a free cap, and multiple independent reviews report it's cloud-only despite marketing that reads as local. Amical is MIT and live on Google Play, but its own docs never state whether Android transcription runs on-device or in the cloud — an open question this research couldn't resolve either way. Wispr Flow and superwhisper, the two best-known desktop names, are cloud-only and have no Android app respectively.
OpenWispr ships on macOS and Android as one project, MIT-licensed, with the same on-device architecture on both: NVIDIA Parakeet-TDT by default, or Whisper via whisper.cpp, selectable. Neither build has a cloud transcription path to fall back to or opt into — the source is public, so that's a checkable claim rather than a marketing one.
This isn't a claim that OpenWispr beats every desktop competitor on macOS, or every Android competitor on Android — several comparisons on this site show specific places OpenWispr is behind, from VoiceInk's recovery UX to Amical's context-aware formatting. The claim here is narrower and structural: one habit, one license, one architecture, following you from a laptop to a phone, without switching to a different product with a different privacy model on each device.
