Transcribe audio and video on your Mac
Transcribe voice memos, mp3, m4a, mp4 and mov files on your Mac, offline, with timestamps you can click, a summary if you want one, and SRT or VTT export.
If you only use Descript for transcripts, Koi, MacWhisper and Aiko transcribe audio and video on your Mac, with no media hours and nothing uploaded, and export SRT or VTT subtitles. TurboScribe is the cheap cloud option. If you edit video or podcasts by editing text, Descript is still the better tool.

Start here
Descript is a full video and podcast editor. You edit the recording by editing its transcript, and it adds AI tools on top: Studio Sound, Remove Filler Words, clips, voice clones, translation and dubbing. Transcription is how it works, so every plan has it, Free included.
That's also why people go looking. If all you want is the text of an interview, a lecture or a meeting, you're paying for an editor you don't open, your media goes to Descript's servers, and every file counts against your monthly media hours. This page is for that person: transcription on a Mac, without the editor. If you edit video or podcasts, the answer may be to stay, and we say when below.
We make Koi, one of the apps below, so read this with that in mind. We didn't run accuracy tests. Every fact about the others comes from their own sites and help pages, checked October 21, 2026.
The facts
Sources: Descript pricing, its transcript export help page and its download page. Descript says you can delete your account and wipe your data from its servers, which tells you where the data lives.
The list
Best for: Transcripts made on your Mac, with no media hours to count
Koi transcribes audio and video files on your Mac: m4a, mp3, wav, aiff, caf, mp4, mov, m4v and voice memos. A page opens with a line under each timestamp and the sound to play back; click a time and it jumps there. Fix a word and the times stay right. Export Subtitles (SRT) or (VTT), each line a cue with your edits in it, and drop them into your video editor. Nothing is uploaded and there's no limit on minutes.
Koi also records what Descript would make you upload. Tap Fn + ⌃ on a call and Koi records it on your Mac, as audio or a video of the screen, written down as You and Them; pick In person for an interview or a class in the room. Say yes when it ends for a summary and your to-dos, which sends the transcript's words, never the sound, to Koi's AI.
The honest gaps: Koi edits text, not video. It doesn't cut the recording when you delete words, name speakers in a file, remove filler words from the audio or export to Premiere or Final Cut. Koi is Mac only and needs a plan: Pro is $20 a month or $192 a year after a 3-day trial that needs a card, or Lifetime from $59, paid once.
Best for: Local transcripts with speakers and many export formats
MacWhisper transcribes files on your Mac with Whisper and Parakeet models, in 100 languages, and exports .txt, .md, .pdf, .html, .docx, .srt and .vtt. The free version handles files; Pro is €64 once, with lifetime updates. It can tell up to 8 speakers apart, which matters for interviews and podcasts.
The weakness: no editing of the media, and version 15.2 needs macOS 15, TidBITS reports.
Best for: One file, one transcript, $24 once
Aiko transcribes on your device with Whisper large v2 on a Mac, in 100 languages, and exports text, SRT, JSON and CSV. $24 once covers its Mac, iPhone and Vision Pro apps, with a 14-day full trial through TestFlight.
The weakness: no speaker labels and no editing in the app, so SRT out to your editor is as far as it goes.
Best for: Cheap, unlimited cloud transcripts
If uploading is fine, TurboScribe is the closest thing to Descript's transcription without the editor: Whisper on its servers, 98+ languages, speaker labels, and PDF, DOCX, TXT, CSV, SRT and VTT exports. Free is 3 files a day up to 30 minutes each; Unlimited is $20 a month or $10 billed yearly, with files up to 10 hours.
The weakness: it's a website, so your files are uploaded. See our TurboScribe alternatives.
Best for: Subtitles in many languages, with a human option
Happy Scribe transcribes and subtitles 150+ languages and dialects in the cloud, keeps recordings in the EU, and can have a person proofread from $2 a minute. Basic is $17 a month for 120 minutes, or $8.50 a month billed yearly; Pro unlocks all 15+ export formats.
The weakness: metered minutes, and a 90-minute cap per recording on Basic.
Best for: Free, offline subtitles
Buzz transcribes and translates offline with Whisper, in more than 90 languages, and exports CSV, SRT, TXT and VTT. Buzz Classic is free and open source, listed for Windows, Linux and Intel Macs, and a separate Buzz on macOS is sold on the Mac App Store.
The weakness: plain, and more setup than the others.
How to
In Descript, once your file is in a project and transcribed, open Export, pick the transcript, and set the file format to .docx, .txt, .rtf, .md or .html. For subtitles, open Export, choose the Subtitles tab and pick SRT or VTT, with options for speaker labels and line length.

Cost
Descript counts media hours, and they count what you upload or record, not only what you transcribe. Hobbyist gives 10 hours a month. If you transcribe a two-hour lecture every weekday, that runs out in the first week, and top-ups are only on Creator and Business.
Local apps have no meter, because the work happens on your Mac. Koi transcribes files and records calls with no limit on every plan; MacWhisper and Aiko are paid once. TurboScribe's Unlimited has no cap on hours either, in the cloud. If you want a few transcripts a month and nothing else, Descript's free 60 minutes may be all you need.
Workflow
If you edit in Final Cut Pro, Premiere or DaVinci Resolve and only used Descript for captions, a local app fits in: transcribe the export on your Mac, fix the words, save SRT or VTT, import it into the editor. Koi's subtitles use each timed line as a cue, with your edits, so what you fixed is what shows. For recording the raw material, see recording a Zoom meeting on a Mac or recording your Mac's sound.
Before you switch
Speakers
This is where Descript is strongest among the tools here, and it's worth being straight about it. Descript detects speakers and helps you name them; TurboScribe and MacWhisper also tell speakers apart. Koi doesn't in a file: you get one line per stretch of talk, with its time.
Koi does split a call it records itself: your microphone is You, the Mac's sound is Them. So if your interviews happen over Zoom, Meet or FaceTime, recording them with Koi in the first place gets you the two sides apart, which a file dropped in afterwards can't. For an interview across a table, In person records it through your microphone with the sound kept, but without speaker names.
Calls
Descript can record remote guests in its Rooms. If you only need the conversation and its transcript, Koi records any call app from your Mac with no bot and no link to send: tap Fn + ⌃, pick Online call, then Audio only or Audio and video. See our list of call recorders for Mac for more.
