Cutting, noise reduction, loudness, speed and pitch, effects, conversion, recording and loudness metering all run in the browser — 32 local tools. Processing happens on your device with no server cost, so there is no charge, no usage limit, no watermark and no account.
Cloud AI: a daily free allowance
Transcription and AI editing need cloud models. They need no login and no card and include a daily free allowance metered by TutuAgent; when it runs out you are told, and local features keep working. This site adds no limits of its own.
