Turn Voice Notes into Structured Text

Record in the browser or upload supported audio, auto-format the transcript, then rewrite or translate without leaving the note.

Workflows

Record live → Transcript: Use the in-browser recorder to capture a note and send it through our speech engine for text.
Upload hours of audio → Chunked processing: Compress and chunk MP3, M4A, WAV, WebM, or MP4 uploads so long memos finish reliably.
Transcript → Outcome-first rewrite: Turn rough speech into cleaned text, notes, summaries, messages, or custom rewrites with matrix tuning.
Transcript → Translate + export: Translate in 100 languages, copy the cleaned text, share, or download the encrypted audio.

Does it work offline?: Sondeas runs in your browser; an internet connection is required to process audio.

Do credits expire?: Paid credits purchased through Stripe never expire. Promotional trial credits follow the expiry shown when they are granted.
