Free voice and audio tools
Small, free utilities for the things people actually need to do with a voice memo. No account, no watermark, no email address — open one and use it.
Speech to text
Transcribe a voice memo
Upload a recording or record in your browser and get an accurate transcript in seconds.
Accepts m4a, mp4, mp3, wav, webm, and ogg up to 10 MB and 5 minutes. Detects the spoken language automatically. Your audio is processed in memory and never stored.
Format conversion
Convert an audio file
Convert voice memos and audio files between MP3, M4A, WAV, OGG, FLAC, and WebM.
Runs entirely in your browser — your files never leave your device, so there is no upload limit and no sign-up.
Doing this more than once?
These tools handle one file at a time. If you record voice notes regularly, Chronicle transcribes every one automatically and makes them searchable — ask “what did I say about the kitchen renovation?” and get the answer back, with the original recording as proof.
