You don't have to pay for accurate voice dictation on Mac in 2026. Here are the five best free voice-to-text options, ranked by what you actually get without spending a cent.
At a glance
| App | Truly free | Local | Free word limit | Custom vocab | |---|---|---|---|---| | Apple Dictation (built-in) | Yes | Partial | Unlimited | Limited | | JustVoice | Yes (5,000 words/mo) | Yes | 5,000/mo | 20 terms | | Aiko | Yes | Yes | Unlimited | No | | VoiceInk (open source) | Yes | Yes | Unlimited | Yes | | MacWhisper (free demo) | Trial | Yes | Limited demo | Yes |
The honest answer: there isn't one app that's best for everyone. It depends on whether you want live system-wide dictation, file transcription, custom vocabulary, or just the simplest path.
1. JustVoice — best free tier for live dictation
What you get free: 5,000 words per month of local Whisper transcription, custom dictionary (20 terms), 10 voice snippets, 7-day note history, system-wide dictation into any Mac app. Why it's the pick: It's a real free tier — not a trial, not a hobbled demo. 5,000 words is enough for daily journaling, dozens of emails, lecture notes, or a few thousand words of prose every month. Audio stays on your Mac. Trade-off: For unlimited words and all Whisper models, you'll need Plus ($5/mo) or Pro ($9/mo). Download JustVoice free →2. Apple Dictation — best built-in option
What you get free: Already on your Mac. Unlimited use. Works in any app via the built-in dictation shortcut. Why it's good enough for many: For short voice memos, search queries, and casual SMS-length messages, it's plenty. Where it falls short: Lower accuracy than Whisper. Limited custom vocabulary. For many languages, audio routes through Apple's servers — not fully on-device. No code dictation, no snippets, no app profiles. How to enable: System Settings → Keyboard → Dictation → toggle on. Default shortcut: pressfn twice.
3. Aiko — best free file transcription from a trusted dev
What you get free: On-device transcription of audio files. Built by indie dev Sindre Sorhus. Why it's good: Free forever, no account required, runs entirely on your Mac. Available on Mac and iOS. Trade-off: File transcription only — drop in an audio file, get text out. Not built for live dictation. No system-wide hotkey.4. VoiceInk — best open-source option
What you get free: Whisper-based local dictation, fully open source, no subscription. Why people pick it: Auditable code, scriptable, no commercial dependency. Active community. Trade-off: Less polished than commercial options. No built-in AI cleanup. No code dictation mode. Setup is more involved.5. MacWhisper Free — best for occasional file transcription
What you get free: Limited file transcription via the free demo tier. Paid tiers ($24+) unlock full features. Why it's worth knowing about: For one-off interview or podcast transcription, the free tier may cover your needs. Trade-off: Not really a free product — it's a demo of a paid one. For ongoing use, you'll pay.Which should you pick?
If you want the most generous free tier with the most features for daily live dictation, pick JustVoice.
If you just need occasional voice memos with zero install, use built-in Apple Dictation.
If you only need file transcription and trust the developer, pick Aiko.
If you want fully open source software, pick VoiceInk.
How to make any free dictation app feel premium
Three things compound:
- Add custom vocabulary aggressively. Names, jargon, project nouns. Even free tiers usually let you add 20–50 entries. Use them.
- Get a decent microphone. The MacBook built-in is OK, AirPods are better, USB condenser is best.
- Speak in complete thoughts. Whisper transcribes context-aware — full sentences transcribe better than fragments.
When free isn't enough
The point at which free becomes insufficient is usually one of:
- You've blown past the word limit (typically 5,000–10,000 words/month)
- You need a code dictation mode for development work
- You need cloud sync across devices
- You need AI cleanup or rewriting on top of raw transcription
- You need premium accuracy for technical, medical, or legal vocabulary
