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.
Free trial: 3 transcriptions per calendar month, each up to 10 minutes, no account — as plain text. Speaker separation (“who said what”) and files up to 4 hours are part of the paid offerings: day pass €2.99, credit €4.99, Pro €8.99/month.

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 a subscription?+
Not for the free trial. You only need an account to buy a plan (day pass, credit or Pro) — a subscription is never required. Technical anti-abuse limits apply.
How long is processing data retained?+
Recognition runs through OpenRouter with zero data retention — the providers (Microsoft Azure, DeepInfra, Groq) store neither audio nor text. Sprechverlauf deletes uploaded audio files after processing, at the latest after two hours, and keeps the transcript in memory for at most two hours. Only signed-in users get an encrypted copy in their account, which they can delete at any time.
Video uploads, speaker names and subtitles+
Premium: upload videos (MP4, MOV, WebM, up to 100 MiB), name speakers and review subtitles before exporting SRT or VTT. The video is deleted from our server one hour after upload. Your encrypted transcript stays in your account until you delete it. Only the extracted audio is sent for transcription.
