Completely private AI-polished dictation
for your Mac.
Hold ⌥ Space, speak, release. Echo Flow turns rough speech into polished text locally, then lets you rewrite selected text anywhere.
Echo Flow AI runs locally on your Mac after a one-time setup download. Your dictated audio, transcripts, and rewritten text are not uploaded for polishing.
Context-aware transcription that adapts to the app you're in. Lands exactly where your cursor is.
Clean up rough text, make it clearer, tighten it, turn it into email or Slack-ready replies, extract action items, or keep it verbatim.
Two on-device models. Pick what fits your Mac.
Echo Flow AI runs entirely on your Mac after a one-time download. No cloud, no account, no data leaves your machine. Choose the model that matches your hardware.

Review before it lands.
Enable Preview Before Paste and see your polished text in a frosted-glass popup before it goes anywhere. Return to paste. E to edit. Esc to discard. Build trust with AI-polished output — no more "oh no" moments.
Subtle start and stop chimes confirm the system heard you. Optional, respects system sound settings, and adds a layer of polish you didn't know you needed.

- check No auto-paste timer — you choose Paste, Edit, or Discard
- check Audio feedback: ascending chime on start, descending on stop
Two shortcuts. Infinite possibilities.
Dictate when you have something to say. Rewrite when you have something to refine.
Dictate
- 1. Hold ⌥ + Space. The overlay appears instantly.
- 2. Speak naturally. Echo Flow reads the room — Mail→email, Slack→casual, Code→verbatim.
- 3. Release. Polished text lands exactly where your cursor is.
Rewrite

"It's not just dictation — I select rough text I already wrote, choose a rewrite action, and keep working in the same app. It feels like a rewrite assistant built into the whole Mac."

Questions & Answers
How does Echo Flow work?
Dictate: Hold ⌥ + Space, speak naturally, then release. Your words are transcribed on-device, polished with context-aware tone, and pasted right where your cursor is. Rewrite: Select any text and press ⌥⇧Space to open the rewrite palette for cleanup, clarity, email, Slack replies, action items, recaps, verbatim preservation, and plain English.
What is Smart Context?
Echo Flow detects which app you're in and automatically selects the best tone. Mail → professional emails. Slack → casual and concise. Code editors → verbatim, no polish. Notes → structured and bullet-friendly. You can override per app — it remembers your preference.
What is the Rewrite Palette?
Select any text in any app and press ⌥⇧Space. Echo Flow shows 9 practical actions: Clean Up (grammar and punctuation), Make It Clear (clarity), Tighten (shorter), Turn Into Email, Slack Reply, Action Items, Quick Recap, Keep Verbatim, and Plain English. It remains available after the dictation trial ends.
Is my voice data private?
Yes. Your dictated audio, transcripts, and rewritten text stay on your Mac and are not uploaded for polishing. Echo Flow may contact servers for setup downloads, update checks, licensing, purchase redirects, and optional email signup — not to process your writing.
Does it work offline?
After setup, dictation and rewrite processing are designed to run locally. Some operational features still need the internet: the one-time Echo Flow AI setup download, update checks, license validation, purchase redirects, and optional email signup.
Which apps does it work with?
Anywhere you can type. Gmail, Slack, Notion, VS Code, Messages, Word, Apple Mail, Notes — doesn't matter. Echo Flow pastes wherever your cursor is focused. The rewrite feature works on selected text in any app.
What Mac do I need?
macOS 15 or later on an Apple Silicon Mac (M1 or newer). Echo Flow AI requires a one-time setup download, then runs locally on your Mac.
Is there a subscription?
No. Echo Flow gives you a free 14-day trial for dictation, then a one-time purchase for lifetime dictation access with free updates. The rewrite palette remains available after trial expiry, so the app stays useful even before you buy. Earlybird: $69.99. After the first 500 users: $139.99.
