AI dictation for Mac

AI dictation on a Mac means you talk the way you talk and get text that reads the way you'd write. Sayburst does it with models that run on your own Mac: hold fn, ramble, correct yourself, let go, and a clean sentence, a laid-out email or a bulleted list lands at your cursor in any app.

The AI part isn't one feature. It's three layers stacked on top of each other, and knowing what each one does tells you what to expect, and what to switch on.

#The three layers

1. Speech recognition. A neural speech model turns audio into words. Sayburst's default is Parakeet v3, running on the Mac's Neural Engine; Whisper models cover 99 languages. This layer is about hearing you correctly.
2. Cleanup. Instant, on-device and always on in the Clean mode: fillers like "um" and "uh" go, accidental repeats go, capitals and punctuation are fixed, "new paragraph" and "bullet point" become structure, and self-corrections are resolved.
3. Sayburst Writer. An optional AI model (Qwen3 4B) that runs on your Mac's GPU and turns talk into writing. Emails get a greeting, paragraphs and a sign-off; spoken lists become bullets; "Tuesday at 3… actually, no, Wednesday" becomes "Wednesday at 3". It's a 2.5 GB download, needs no account or key, and works best with 16 GB of memory.

Cloud dictation tools run these layers on a server. Sayburst does all three on your Mac, and lets you swap the third layer for a model you already use, local or cloud.

#How to set it up

1. Install Sayburst and grant Microphone and Accessibility. The speech model downloads once.
2. Add Sayburst Writer. Download it from Sayburst's settings, or point Sayburst at Ollama or LM Studio on your Mac, or add your own API key for OpenAI, Anthropic, OpenRouter, Groq or any OpenAI-compatible service.
3. Give each app a mode. Email for Mail, Message for Slack, Notes for your outliner, Clean for documents. Then click into an app, hold fn, talk and let go. You can override the mode for a single dictation from the menu bar.

#One sentence, three results

What you say, heading out the door:

"Hi Marcus, um, so for the offsite I think we should book the, the lake house for Thursday, actually no, Friday and Saturday. Can you check if it sleeps twelve? Thanks."

In Slack with Message mode, you get a chat line:

Hi Marcus, so for the offsite I think we should book the lake house for Friday and Saturday. Can you check if it sleeps 12? Thanks

In Mail with Email mode and Sayburst Writer, you get an email:

Hi Marcus,

For the offsite, I think we should book the lake house for Friday and Saturday. Can you check if it sleeps 12?

Thanks

Same words in, different shape out, chosen by the app you're in. A spoken packing list in Notes mode ("laptop charger, the badge, two printed copies of the contract, and the HDMI adapter") lands as four bullets.

#What the AI won't do

This is where AI dictation tools differ most, and where you want guarantees:

• It won't follow your words as instructions. Say "write me a poem about Mondays" into a document, and that sentence is what you get. That's essential when you dictate prompts into Claude or ChatGPT, where the AI on the other end should do the work, not your dictation app.
• It won't add or summarize. Writer cleans and shapes; it doesn't invent a closing paragraph or shorten your point.
• It won't change your numbers. If a rewrite would alter a number you said, Sayburst types the cleaned transcript instead.
• It won't translate. You get text in the language you spoke.
• It won't hold you up. A Skip button inserts immediately if you don't want to wait for the rewrite.

#AI dictation options on a Mac

Facts from Apple's dictation guide (the Apple Intelligence improvement is described for macOS 27), Wispr Flow's pricing and its data controls page, all checked at the end of October 2026. Apple Dictation is free and fine for short notes. Wispr Flow is the pick if you need the same AI dictation on Windows and Android. For AI dictation on a Mac without a subscription or a server, Sayburst is built for exactly that. The Sayburst vs Wispr Flow comparison goes deeper.

#Where your words go

• Recognition runs on your Mac; Sayburst never uploads audio.
• Cleanup runs on your Mac, instantly.
• Sayburst Writer runs on your Mac's GPU, with no internet, as covered in AI dictation that never leaves your Mac.
• A cloud writer, only if you add one: the transcribed text (and any context you switch on) goes to that provider, never audio, and Sayburst shows exactly what will be sent before it's enabled.
• The destination app stores what you dictate the same way it stores typing.

Because nothing in the default path needs a server, Sayburst also works with no internet at all.

#Tips for getting the most from AI dictation

• Talk, don't compose. Self-corrections, false starts and "wait, let me rephrase" are fine. That's what the layers are for.
• Feed it your vocabulary. Names and jargon are where any speech model slips. Add them once and Sayburst corrects near-misses. See how vocabulary and replacements work.
• Rewrite after the fact. Select any text, hold the rewrite shortcut and say "make this friendlier" or "make it shorter". The selection is replaced.
• Ask without switching apps. Hold the ask shortcut and ask a question; the answer shows in a panel with Copy and Insert.
• Give it context only when it helps. Selected text, clipboard text or the current window's text can be passed to the writer. Each is off by default.

#Limits worth knowing

Writer works on 8 GB Macs but is slower; 16 GB is the comfortable minimum. Text arrives when you finish speaking, not word by word. Sayburst needs an Apple silicon Mac with macOS 14 or later, and there's no Windows, phone or web version.

Questions people ask

What is AI dictation?

Dictation where AI models do more than transcribe: they remove fillers, resolve corrections like 'Tuesday, actually Wednesday', fix punctuation and lay text out as an email or a list. Sayburst does all of this on your Mac.

Is there AI dictation for Mac that works offline?

Yes. Sayburst's speech models, its cleanup and Sayburst Writer, its optional on-device AI model, all run on your Mac with no internet after a one-time download.

Does AI dictation change what I said?

Sayburst Writer doesn't summarize, add content or translate. It treats your speech as text to clean, never as instructions, and if a rewrite would change a number you said, Sayburst types the cleaned transcript instead.

Can I use ChatGPT or Claude models for dictation cleanup?

Yes. Sayburst can use your own OpenAI, Anthropic, OpenRouter or Groq API key as its writer. Only the transcribed text is sent, never audio, and you see exactly what will be sent first.
