Every manufacturer ships a different recorder app, and they do not all save the same kind of file. M4A, 3GP and AMR all upload here as they are, from Chrome on the phone or from a computer. Files over 500 MB continue on the upload page. A pack from $4 opens the full transcript · packs from $4 for 500 minutes.
How it works
The awkward part is usually finding it, not uploading it.
Open the Files app and look under Internal storage. Recorder apps usually write to a folder named Recordings, Sounds or Voice Recorder. Some keep recordings inside the app until you share them out.
Open this page in Chrome on the phone and pick the file, or copy it to a computer over USB and drop it in from there. Up to 500 MB goes straight into the box.
The transcript comes back with every word timed. Export TXT, DOCX, SRT, VTT, MD or JSON, and the recording stays in a searchable library.
Maker by maker
Android does not standardise this, so it is worth knowing what your phone did.
Whichever you have, upload it as it is. AMR and 3GP are narrowband by design, so the recording itself is the ceiling on accuracy — hold the phone closer rather than reaching for a converter.
What it is good for
Anything with a voice in it and a reason to read it later.
Put the phone in the middle of the table. Speakers are not labelled; every line carries its timestamp.
An hour of M4A is a small file, so a term of lectures fits a phone and uploads one at a time without thinking about size.
A phone is the recorder most people actually have with them — the same job as research interviews and interviews for journalists.
TXT, DOCX, SRT and VTT hold the words without speaker labels. JSON is the export that keeps the speaker of every segment.
Pricing
A pack from $4 opens the full transcript. After that, one-time packs: $8 for 1,000 minutes, $12 for 2,000 minutes and $24 for 5,000 minutes. Credits never expire.
A 30-minute meeting is $0.24 on the $8 pack. Two meetings a week for a year is about 3,120 minutes, covered by the $12 pack of 2,000 plus part of another.
