Updated 6 October 2026 · 1 min read
In shortA 2–3 hour lecture fits: an hour recorded in SozAI is about 43 MB and the file limit is 500 MB. You only need enough minutes for the whole recording and a phone that does not go to sleep.

Will your minutes be enough

Before transcribing, the server measures the recording and compares it with your balance. If you have fewer minutes, transcription does not start. While recording, the app warns you when the take is longer than your balance. See When are minutes charged.

Large file and a dropped connection

Files over 20 MB are sent in 5 MB parts, and after a dropped connection the upload resumes instead of starting over.

If the recording was interrupted

Causes and what to do: Recording on the phone was interrupted.
