Direct answer — Is free transcription software for Mac good enough, or should you pay? Free transcription software for Mac is good enough for short files and occasional use: whisper.cpp, Voice Memos and the free tiers of MacWhisper and Weesper Transcribe all turn speech into text. You pay when you need long files, batches, editing, search or subtitle exports. On the Mac, that upgrade is usually a one-time purchase, not a subscription.
Looking for free transcription software for Mac usually starts with a practical need: an interview, a lecture or a podcast episode is sitting on your disk and you want the words out of it. The good news is that several free options do the job well. The question is what “free” covers, and where each one stops.
This comparison sets free tiers against paid upgrades, using what each publisher states on its own pages as read on 11 November 2026. Prices stay in the currency each vendor publishes; none has been converted.
What can free transcription software on a Mac actually do?
Free options transcribe; paid upgrades make the transcript useful at scale. Most free tiers produce accurate text from a recording, then limit length, volume, export formats or the tools around the text.
There are three kinds of free on the Mac:
- Free open-source engines such as whisper.cpp: no limits, but no app either.
- Built-in tools such as Voice Memos: free with macOS, tied to their own recordings.
- Free tiers of paid apps, such as MacWhisper and Weesper Transcribe: a real app with a capped feature set.
A fourth kind, free cloud plans, also exists. They are covered below, because their limits work differently.
Which free transcription options exist for Mac?
Five free options cover most needs. The table summarises what each publisher states.
| Option | Type | Where audio is processed | What free gives you | Main limit of the free version |
|---|---|---|---|---|
| whisper.cpp | Open-source engine (MIT) | On the Mac | Everything; no paid tier | Command line; whisper-cli takes 16-bit WAV files |
| Apple Voice Memos | Built into macOS | Not specified by Apple | Transcript of Voice Memos recordings, search, copy | Not available in all countries or regions |
| MacWhisper Free | Free tier of a paid app | Local models | A tier its site calls “Free forever” | The homepage does not detail the Free/Pro split |
| Weesper Transcribe Free | Free tier of a paid app | On the Mac, nothing uploaded | Files up to 15 minutes at full quality, one at a time | Plain text only; no batch, editing or search |
| Otter Basic | Free cloud plan | Otter’s online service | 300 monthly transcription minutes | 30 minutes per conversation; 3 lifetime file imports |
whisper.cpp: free with no ceiling, if you use the Terminal
whisper.cpp is an open-source C/C++ port of OpenAI’s Whisper model under the MIT licence. Its repository calls Apple Silicon a first-class citizen and lists Mac OS on Intel and Arm.
Nothing is capped, but nothing is packaged either. The whisper-cli example currently runs only with 16-bit WAV files, so you convert other formats first, and you edit and export the text with other tools. Our whisper.cpp setup guide walks through the installation.
Voice Memos: free, for what you record in it
Voice Memos on a Mac transcribes the speech in its own recordings. You can search across transcripts and copy the text into another document.
Apple notes that audio transcription is not available in all countries or regions. Its guide describes no import of other audio files and no subtitle export. Our guide to transcribing Apple Voice Memos on a Mac shows what you can do with them.
MacWhisper Free: a generous entry point
MacWhisper’s site lists a free tier, “Free forever”, next to MacWhisper Pro. It says it uses local models, so you can process sensitive content without data leaving your Mac. That makes the free tier a sensible first stop for private recordings.
The homepage does not say which features belong to which tier, so check inside the app what your files need before you count on the free version.
Weesper Transcribe Free: full quality, capped length
Weesper Transcribe is free to download from the Mac App Store and transcribes files up to 15 minutes at full quality. The free tier uses the same on-device engine as Pro, so a short file gives you the same transcript you would get after upgrading.
The free version handles one file at a time and gives you the text to copy or save as plain text. It runs on Apple Silicon and on Intel Macs with AVX2 (Intel Core 4th generation Haswell or later), on macOS 13 or later.
Otter Basic: free minutes, in the cloud
Otter’s free Basic plan includes 300 monthly transcription minutes, with a maximum of 30 minutes per conversation and 3 lifetime audio/video file imports. It is designed around meetings: its pricing page highlights Zoom, MS Teams and Google Meet, AI chat and speaker identification.
For a Mac user with a folder of existing recordings, the 3 lifetime imports are the limit that matters. Our comparison of on-device and cloud transcription covers the privacy trade-off in detail.
What do you get when you pay?
Paying mainly buys length, volume and output. The speech engine is often the same; what changes is everything around the transcript.
| Paid option | Price model | What the upgrade adds |
|---|---|---|
| Weesper Transcribe Pro | One-time App Store purchase | No length limit, batch processing, editing with clickable timestamps, keyword and semantic search, SRT, VTT, DOCX, PDF and other exports |
| MacWhisper Pro | €64 one-time licence (direct download) | Lifetime updates; the full feature set of the Pro tier |
| Aiko | $24 one-time for all platforms | The whole app on macOS, iOS and visionOS; no free tier |
Weesper Transcribe Pro
Pro is a one-time lifetime purchase through Apple’s App Store, with no subscription. It removes the 15-minute limit, so multi-hour recordings work, and it unlocks batch processing of a queued folder, inline editing, clickable timestamps and search across your whole transcript history, by keyword or by meaning.
It also unlocks the pro exports. Weesper Transcribe exports nine formats in total: TXT, Markdown, SRT, VTT, DOCX, PDF, HTML, CSV and JSON. The App Store shows the current Pro price before you buy. See the full workflow on the Weesper Transcribe page.
MacWhisper Pro
MacWhisper Pro is €64 as a one-time licence that includes lifetime updates, when bought from macwhisper.com. It is the broadest toolkit in this category, and many Mac users consider it the reference.
One detail matters for the price: MacWhisper’s documentation explains that the Mac App Store edition, called Whisper Transcription, uses weekly, monthly or yearly subscriptions and does not accept external licence keys. Our list of MacWhisper alternatives compares the pay-once apps around it.
Aiko
Aiko costs $24 as a one-time purchase covering macOS, iOS and visionOS, and transcribes on the device; its site says your audio is never uploaded. There is no free tier, but the full app can be tried free for 14 days through TestFlight.
On the Mac it uses the large Whisper model, which needs an Apple Silicon Mac with at least 16 GB of RAM, and the current version asks for macOS 26.6 or later. Aiko has no built-in batch transcription; its developer suggests Shortcuts instead.
Have a recording waiting? Try Weesper Transcribe on a real file: it is free for files up to 15 minutes on the Mac App Store, with a one-time Pro upgrade when you need longer files.
When is free transcription software enough?
Free is enough when your files are short, occasional and only need to become text. Four signs that you can stay on a free option:
- Your recordings are short. Voice notes, short interviews or clips under 15 minutes fit Weesper Transcribe’s free tier.
- You only need the words. Copying text or saving plain text covers notes, quotes and drafts.
- You transcribe now and then. One file at a time is no constraint when you have one file.
- You are comfortable with the Terminal. whisper.cpp has no tier at all, at the cost of doing the conversion and editing yourself.
When does paying make sense?
Paying makes sense when the transcript is part of your work, not a one-off. The upgrade earns its place in four situations:
- Long recordings. A two-hour lecture or podcast episode goes beyond free length limits.
- A backlog of files. Batch processing lets your Mac work through a folder while you do something else.
- Subtitles and documents. SRT, VTT, DOCX and PDF exports are paid features in Weesper Transcribe.
- An archive you come back to. Search across past transcripts saves you from reopening files one by one.
Before paying, check the price model. A one-time licence costs the same whether you use it for a month or for years; a subscription keeps billing. Our breakdown of subscription vs one-time purchase transcription apps shows how the two compare over time.
Which option should you choose?
Match the option to your files, your Mac and your budget:
- Stay with Voice Memos if your recordings already live there and copying the text is enough.
- Choose whisper.cpp if you want free, unlimited and scriptable, and the command line does not put you off.
- Start with MacWhisper Free or Weesper Transcribe Free if you want an app that keeps audio on your Mac; Weesper Transcribe also runs on Intel Macs with AVX2 and on macOS 13.
- Upgrade to a one-time Pro when files get longer, more numerous or need subtitles and documents.
- Choose Aiko if one fixed price across Apple devices matters more than batch and editing tools, and your Mac has 16 GB of RAM.
