Local speech recognition. Your device listens. Nobody else.
Bygmind transcribes recordings in 25 languages directly on your smartphone – including speaker recognition. No cloud requirement, no account, verifiable in airplane mode.
Cloud, on-premise or on-device?
"Local speech recognition" can mean three different things. They differ in where your audio goes – and how much effort it takes to get there.
Cloud speech recognition
Your audio is sent to someone else's servers, transcribed there and sent back. Convenient – but your recordings leave the device, and you need data processing agreements, transfer assessments and trust in the vendor's policies.
On-premise
Speech recognition on your own servers in your own data center. Full control, but a real IT project: hardware, operations, maintenance and updates included.
On-device – how Bygmind works
The most consistent form of "local": the speech model runs directly on your smartphone. No servers to operate. No transfers to audit.
What runs on your device: everything.
25 languages, fully offline
English, German and 23 more languages – transcription runs entirely on the device, even with no signal at all.
Speaker recognition included
Who said what? Speakers are separated locally and recognized via voice ID. Voice profiles never leave the device.
Verifiable in airplane mode
Turn on airplane mode, record, transcribe. What works offline cannot send data – the simplest privacy proof there is.
No account, no sign-up
Download the app and start. Without registration there is no user data sitting on a server anywhere.
Privacy without paperwork
When no audio leaves the device, there are no cross-border transfers and no processing agreements to negotiate for transcription. The GDPR conversation gets very short.
Summaries: local or your model
The AI agent summarizes with a local model – or, if you choose, with Claude, GPT & co. via your own API key. Your decision, per request.

Common questions about local speech recognition
Yes. Bygmind transcribes entirely on your smartphone – in 25 languages, including speaker recognition. You can verify it: turn on airplane mode, record, transcribe. It works exactly the same as with internet.
No. Modern smartphones are powerful enough to run speech models directly on the device. You get the data sovereignty of an on-premise solution without hardware, operations or an IT project – the app is enough.
Local processing is the most privacy-friendly architecture: audio and transcript never leave the device, there is no cross-border transfer and no data processor for transcription. You still need the consent of the people in the conversation, of course.
Bygmind transcribes in 25 languages directly on the device, including English and German. Speaker recognition also runs locally.
Modern on-device speech models deliver transcripts that are very good for meeting notes, dictation and documentation in everyday use – including speaker separation. The practical difference is less about accuracy and more about where your audio goes.
They stay on your device. If you want to sync between devices, you can opt in via Bygmind Cloud, your own Nextcloud or S3 – but you don't have to. Export to open formats is possible at any time.
Speech recognition you can verify.
