Speaker diarization on Mac · Local-first voice
Speaker diarization on Mac
for local transcripts.
Speaker diarization turns a wall of transcript text into speaker turns. MacParakeet uses local meeting capture and local speech workflows so the labels stay attached to an artifact you control.

Why diarization matters
Who said it is often as important as what was said.
A meeting transcript without speaker context is hard to trust. Speaker labels help recover decisions, questions, objections, and commitments without replaying the full call.
Named speaker workflow
Rename speaker labels and keep the transcript readable after the call.
Better summaries
AI prompts can produce cleaner action items when the transcript preserves speaker turns.
Interview analysis
Separate interviewer and guest voices for research, journalism, podcasting, and customer discovery.
Structured export
Use JSON or text formats when downstream tools need speaker-attributed segments.
From audio to speaker-labeled transcript
Diarization makes the transcript usable after the novelty wears off.
01
Record or transcribe

Export with context
Keep speaker context in your notes, summaries, and archive.
Diarized vs flat transcripts
Speaker labels reduce the work after transcription.
