Not uploaded
Cutting, noise reduction, loudness, speed and pitch, effects, conversion, recording and loudness metering all run in the browser. Editor drafts are stored in your browser’s storage (IndexedDB and OPFS).
Uploaded
AI transcription: the audio is uploaded and recognized by the service TutuAgent connects to; the result comes back to your browser.
Cloud saving: after you sign in, projects and their audio are stored on our servers so you can continue on another device; deleted projects go to the trash and are permanently removed when it expires.
Export to TutuDrive: when you choose it, the file is saved to your own TutuDrive.
AI chats
Guest chats with the AI assistant are kept by TutuAgent and cleared after 24 hours; after sign-in they move into your TutuID account.
Statistics
To improve performance, the page reports anonymous processing statistics: device memory and CPU, browser, file size and duration, processing time and failure reasons — never audio content; after sign-in they may be linked to your account. Page views are counted by TutuStat.
