Made for real work
A clear path from recording to finished work.
M4A is the format most phones and voice recorders use, especially iPhone voice memos. Upload the file and BriefVox turns the recording into a clean, speaker-labeled transcript you can read, search, correct and export — no conversion needed.
Transcribe voice memos and recorded calls
Voice memos are one of the most common things people need in writing — interviews, ideas, calls and meetings recorded on a phone. Upload the M4A and review the transcript in the editor, with synced playback so you can click a line and hear it.
Edit and export
Rename speakers, fix wording, and turn the transcript into AI notes — summaries, tasks or quotes. Export TXT or DOCX for documents, or SRT and VTT if the recording belongs to a video.
