Speaker recognition for discussions
Even with multiple contributions, the AI detects who spoke when.
For seminars & study groups
Seminar notes from audio — transcribed automatically
Seminars and group discussions thrive on multiple voices — which is exactly what makes handwritten notes hard. Record the discussion and turn it into notes with speaker attribution and timestamps.

Frequently asked questions
Does this work for discussions with multiple participants?+
Yes. AI-based speaker diarization assigns contributions to different speakers — even with multiple participants in a seminar.
Do I need to know exactly how many people are speaking?+
An approximate figure helps speaker recognition, but it's optional — you can also use automatic detection without an exact number.
Can I pre-load technical terms or names?+
Yes, via the special-words field — that helps names and jargon appear correctly in the transcript.
How do I share the notes with my study group?+
Export the transcript as a Word or PDF file and pass it along.
What do I need to consider legally before recording the seminar?+
You must make sure yourself that you're authorized to record and that all necessary consent from participants is in place. Details are in our Terms of Use and Privacy Policy.
Do I need an account or minute plan?+
No. No account or login is required, and there is no paid minute plan or daily freemium quota. Technical anti-abuse limits apply.
How long is processing data retained?+
Replicate removes API prediction inputs, outputs, files, and logs after about one hour by default. Sprechverlauf does not permanently store audio or transcript content on its own server.
