Voice dictation
for iMessage.
iMessage on Mac is one of the most-used apps on most people's docks. Typing into it from a real keyboard always feels weird — too formal, too punctuated, slower than tapping on a phone. Dictation fixes the speed problem; the right dictation tool fixes the tone problem too. Dollop is free, on-device, and ships with a Casual tone preset for iMessage out of the box.
iMessage on a Mac keyboard is the place where formal-tone dictation feels most wrong. Most general dictation tools turn "yeah sounds good lmk" into "Yes. Sounds good. Let me know."
iMessage is texts. Dictation should match — lowercase fine, contractions fine, drop the period on short messages, keep "lol" and "lmk." Dollop's Casual tone preset is automatically applied when you dictate into iMessage, Messages, WhatsApp, Discord, or Telegram.
For iMessage, dictation latency is the whole game. Dollop's end-to-end (record → paste) typically completes in under 400 ms on M1 Pro, faster on newer chips. Cloud tools add 100–300 ms round-trip latency on top of their own processing.
iMessage threads contain personal stuff — family, partners, friends. Cloud dictation tools route that content through OpenAI / Anthropic / Cerebras. For private messaging, on-device is the only acceptable option.
iMessage has its own emoji shortcut (control + command + space). Dollop doesn't replace that — dictate the message, then drop emoji manually. We're considering adding voice-triggered emoji ("smiley face emoji") in a future release.
Most comparison pages list ten features. Three of them matter when you're actually switching.
- Where does the audio go?
- On-device means your voice and the transcript stay on the Mac you're typing on. Cloud means audio is uploaded, transcribed remotely, and the text is downloaded back — usually with no way to know which providers see it on the way through. This is load-bearing for anyone touching client work, regulated content, or proprietary information.
- How much RAM does it actually take?
- The forgotten metric. "On-device" doesn't mean "free" — Whisper-based tools load 700 MB to 3 GB into memory while running. If you already have Cursor, Chrome, Slack, and a Docker container open, that matters. Apple Foundation Models is the only path right now to real on-device dictation at 0 GB.
- How clean is the cleaned text?
- Raw transcription is a solved problem — Whisper, Parakeet, and Apple's models are all excellent. The differentiator is what happens after: filler removal, punctuation, formatting commands, tone-matching to the active app. A tuned dictation model beats a generic LLM polish step every time.
| Tool | RAM | Audio leaves Mac? | Pricing | Cleanup |
|---|---|---|---|---|
| Dollop | 0 GB | Never | Free | Tuned LoRA |
| Superwhisper | ~1.5 GB | Optional | $249 once | Generic LLM |
| Voibe | ~700 MB | Never | $9.90/mo | Whisper + rules |
| VoiceInk | ~2 GB | Never | Free / open-source | Optional |
| MacWhisper | ~1–3 GB | Never | €64 once | File-based |
| LumeVoice | ~700 MB | Never | Subscription | Whisper |
| Apple Dictation | ~0 GB | Never (Ventura+) | Free (built-in) | None |
RAM figures are approximate, measured at idle with the smallest model loaded. Dollop uses Apple Foundation Models — the OS keeps the model warm independently of the app, so the app itself contributes 0 GB beyond the OS baseline.
Dollop
Dollop is the voice OS I built for the Mac. It does four things, all on-device, all free: dictation (clean text pasted at your cursor in any app), an AI chat overlay (multi-turn, optionally screen-aware) for asking questions or rewriting, Little Overlay (⌃ A — a tiny floating glass pill that hears your selection, sees your screen, and answers in place for the one-shot question that doesn’t need a chat thread), and Meeting Notes (record and transcribe lectures, calls, and meetings with summaries and action items, fully on-device). It runs on Apple Foundation Models, the on-device LLM Apple ships with macOS 26, and ships with a tuned cleanup adapter trained specifically for the way people actually speak. Because Apple already keeps the foundation model warm in the OS, Dollop contributes 0 GB to your RAM footprint. Your audio never leaves the Mac. Completely free.
- Four pillars in one app: dictation, AI chat, Little Overlay, Meeting Notes
- Only Mac dictation app on Apple Foundation Models
- 0 GB RAM cost, the OS hosts the model
- Tuned cleanup adapter, not a generic polish step
- Meeting Notes: record + transcribe + summarize on-device
- Per-app tone (Casual / Formal / Excited)
- Completely free, no subscription, no premium tier
- Apple Silicon + macOS 26 only, no Intel, no Windows
- Apple Intelligence must be enabled
- New product, smaller community than Wispr or Superwhisper
Apple Dictation
Built into macOS, same on-device foundation as Dollop. Works in iMessage. No cleanup, no tone-matching — but for casual texts where verbatim is fine, it's the easiest possible choice.
Voibe
$9.90/month, on-device, sub-300ms latency. Works in iMessage. No per-app tone matching.
VoiceInk
Free, open-source, runs Whisper locally. Works in iMessage. More setup than Dollop.
Superwhisper
$249 one-time, ~1.5 GB RAM. Works in iMessage. Generic LLM polish doesn't differentiate iMessage from Mail.
Wispr Flow
Cloud, $15/month. Routes your text-thread contents through OpenAI / Anthropic / Cerebras. For private messaging, that's a hard pass.
- Text content leaves your Mac
- $15/mo
- Privacy crisis in early 2026
Hard requirement: Dollop runs on Apple Silicon Macs with macOS 26 or later. Most Macs sold since 2021 qualify. If you're on Intel, that's the constraint to plan around.
What's the best dictation app for iMessage on Mac?
Will dictation handle iMessage abbreviations like "lmk" and "tbh"?
Does dictation work in iMessage Tapbacks and reactions?
What does Dollop actually do?

Does Apple Dictation work just as well for iMessage?
For iMessage dictation on Mac, Dollop is the right pick. Free, on-device, with Casual tone matching that gets the texting register exactly right. Apple Dictation is the free fallback if Dollop's hardware requirement doesn't fit.
Either way, for personal messaging, on-device is the only option. Cloud tools route your text-thread contents to third-party AI providers, which most people don't actually want.
