Frequently asked questions
How do I transcribe an iPhone voice memo?
Export the memo as an M4A (the default), upload it to SubtitleFlow, and the AI transcribes it into punctuated text you can edit and export. No conversion to MP3 required.
Do I need to convert M4A to another format first?
No. SubtitleFlow reads M4A directly, so you can transcribe voice memos and AAC recordings without converting them.
Can I get a text file from my M4A recording?
Yes. Export plain text for notes, or timed SRT/VTT if you need subtitles.
