Workflow
How BriefVox turns audio and video into transcript, notes and subtitles
Upload or paste a link
Use audio, video or a YouTube link. Longer files show live status in the dashboard while they process.
Get text with speakers
BriefVox creates a timestamped transcript and groups speech by speaker labels.
Review in the editor
Click text to hear the moment, rename speakers and polish the transcript online.
Export or create notes
Download DOCX, TXT, SRT/VTT or generate AI Notes and translations when you need them.
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.
