MacWhisper vs Aiko: File Transcription Face-Off
MacWhisper and Aiko both turn an audio or video file into a transcript, both run Whisper on your Mac, and both are popular for good reason. So which one should you drop your recording into? Here is an honest, side-by-side face-off, plus the case for when neither is the right tool.
Key takeaways
- Both apps are file transcription tools: you feed in a recording, you get text back.
- Aiko is free and simple; MacWhisper is paid with deeper editing and export features.
- Both lean on local Whisper models, so audio can stay on your Mac.
- Neither types live into apps. For that, on-device live dictation is a different category.
What these two apps actually do
It helps to be precise about the job. Both MacWhisper and Aiko are file transcription apps. You take an existing recording, a meeting, a voice memo, a podcast, an interview, and hand the file to the app. It runs a Whisper speech-to-text model and hands you the words back. Neither is designed to sit in the background and type as you speak into your email or your code editor.
Aiko, from developer Sindre Sorhus, is free and available on both Mac and iOS. Its whole appeal is simplicity: open it, drop a file, wait, copy the transcript. MacWhisper, from Jordi Bruin, is a paid Mac app that wraps Whisper in a much richer interface, with editing, search, timestamps, speaker separation and subtitle export in its higher tiers. Both keep transcription local by leaning on on-device Whisper models, which is a big reason people trust them for private recordings.
MacWhisper vs Aiko: the comparison table
| Feature | MacWhisper | Aiko |
|---|---|---|
| Price | Paid (free tier limited) | Free |
| Platforms | Mac | Mac + iOS |
| On-device Whisper | Yes | Yes |
| Transcript editing | Yes | Minimal |
| Timestamps and speakers | Yes | Limited |
| Subtitle export (SRT/VTT) | Yes | Limited |
| Live dictation into apps | No | No |
The pattern is clear. Aiko wins on price and pure simplicity, MacWhisper wins on depth. If your work is casual, one recording at a time, Aiko is hard to beat because it costs nothing. If you transcribe a lot, need clean subtitles, or want to fix errors inside the app, MacWhisper earns its price.

The gap both apps share: they do not type for you
Here is the honest limitation of a file transcription face-off. Both apps assume you already have a recording. That is perfect for meetings and interviews. It is the wrong shape for the thing many people actually want: to talk instead of type, and watch the words appear directly in whatever they are working in.
Most people speak around three to four times faster than they type, so live dictation is a genuine productivity change, not a novelty. That is a different category from file transcription. Live dictation runs system-wide, listens when you press a shortcut, and inserts clean text at your cursor in email, Slack, Notion, or an editor. If your real goal is writing faster rather than processing old audio, that distinction matters. It is also why comparisons like Wispr Flow vs Otter end up being about two different jobs rather than one winner.
That cleanup step is the second gap. MacWhisper and Aiko give you a faithful transcript of what was said, filler words and all. A live dictation app with on-device AI cleanup can strip the "ums", fix punctuation and grammar, and adapt tone as it goes. BlaBlaType does exactly this: speech recognition and AI cleanup both run locally, so nothing is uploaded, and on the Pro plan it can transcribe audio files too, covering the MacWhisper and Aiko use case as well.
Privacy: are these apps really on-device?
Mostly, yes, and that is a real strength of both. Because MacWhisper and Aiko are built around local Whisper models, your audio does not need to leave your Mac to be transcribed. Always sanity-check settings, since optional cloud models or larger downloads can exist, but the default posture of both is local. That makes either one reasonable for sensitive material like client calls, medical notes or anything under an NDA. It is the same principle that protects people managing conditions like repetitive strain injury who lean on voice tools daily and do not want a server in the loop. BlaBlaType takes the same on-device stance for live dictation: audio and transcripts never leave the Mac.

Download for macOSWhich should you choose?
Match the tool to the job. If you have a pile of recordings to process for free, start with Aiko. If transcription is part of your paid workflow and you need editing and subtitles, MacWhisper is worth it. If you mostly want to write faster by voice, in your own apps, with cleaned-up text, that is a live dictation app, and it is also handy if you code by voice on your Mac or work across many languages. Advanced users sometimes even pair dictation with a command tool like Talon for hands-free control. Many people end up owning both a transcription tool and a dictation tool, because they solve different problems.

Frequently asked questions
Do MacWhisper and Aiko upload my audio?
Both apps are built around local Whisper models, so file transcription runs on your Mac by default. Some optional cloud or larger-model features may exist, so check each app's settings if uploading is a concern. Aiko is free and Mac and iOS native, while MacWhisper is a paid Mac app with more editing tools.
Is Aiko really free?
Yes. Aiko is a free Mac and iOS app that transcribes audio and video files on-device using Whisper. It is simple by design, with fewer editing and export options than a paid tool like MacWhisper.
Which is better for long recordings, MacWhisper or Aiko?
For long recordings that need editing, timestamps, speaker labels or subtitle export, MacWhisper's paid features are usually the better fit. Aiko is better when you just want a quick, free transcript with no setup.
Can I dictate live into apps with MacWhisper or Aiko?
Both are primarily file transcription tools: you drop in a recording and get a transcript back. If you want to speak and have words appear directly in any app as you talk, a live dictation tool like BlaBlaType is the better choice.
