I've just launched a completely cross-platform utility / tool app, Vid2, which converts videos & audio of any file format, to a transcript of any language that you want!
It is supported on Android, iOS, and web, with any transcriptions you make completely persisting amongst the platforms! I've also added a bunch of cool features like TTS, detailed exports of any format, diarization, transcript editing, language translations, etc. etc.!
Would love to hear some feedback on the UX of the app!
