launch-email.txt — TextEdit

Hi team, just wrapping up the launch checklist for Thursday. I'll need final copy from Maya by Tuesday EOD, and the updated analytics dashboard from Sam. Once those land, we're clear to ship.

Faster than your keyboard

People speak about three times faster than they type. FlowKey just lets your hands keep up.

Average typing: 40 wpm. Average speech: 150 wpm. Whisper transcribes locally while you're still talking, so the gap closes the moment you let the key go.

Three steps. Zero friction.

Press the key. Speak. Release.

  1. 01

    Hold Fn anywhere. A Slack thread, a code comment, your terminal, a draft email.

  2. 02

    Speak naturally. Whisper transcribes on-device while you're still talking.

  3. 03

    Let go. The text lands where the cursor is. Punctuation included.

Made for the way you work

One key. Every app you already live in.

Why local

A dictation tool that doesn't send your voice anywhere.

01

100% on-device. Always.

FlowKey ships a local Whisper model that runs on your Mac's Neural Engine. Transcription happens on-device, even in airplane mode. Your voice never reaches a server.

02

Private by design.

No accounts, no telemetry, no analytics. Microphone permission is the only thing FlowKey ever asks for.

03

Cursor-aware.

The text inserts into the field you were already in. No floating window, no copy-paste step, no context switch.

04

AI-formatted output.

FlowKey trims filler, fixes punctuation, and matches the tone of the app you're typing into.

05

Quiet by default.

No background services. No telemetry on by default. Hold the key, talk, keep moving — that's the whole product.

How we compare

FlowKey vs. the rest.

Most dictation tools either send your voice to the cloud or charge you forever. FlowKey is the rare third option.

FAQ

The specific questions.

Is FlowKey really 100% local?

Yes — and you can verify it. FlowKey ships with the Whisper speech model bundled in the app. Block it from making network connections in Little Snitch and it keeps working perfectly. The only network call is a once-a-week update check, which you can disable.

How accurate is it compared to cloud dictation?

Within 1–2% word-error-rate of the best cloud models for English, and faster — because there's no network round-trip. We use a quantized Whisper-large derivative tuned for Apple Silicon's Neural Engine. On an M2 Air, latency is typically under 250ms.

What languages does it support?

70+ languages out of the box, with auto-detection. AI cleanup currently works best in English, French, Spanish, German, Portuguese, and Japanese — more on the way.

Will it slow down my Mac?

FlowKey idles at near-zero CPU. The model only loads into the Neural Engine when you press the shortcut. Active dictation uses ~6–8% CPU on M-series Macs. Battery impact during a typical workday is negligible.

Does it work in (insert app)?

Yes. FlowKey is a system-level keyboard, so it works anywhere your keyboard works — Mail, Messages, Slack, Notion, Figma, VS Code, Xcode, Terminal, Safari, Chrome, browser textboxes, fullscreen apps, even login screens.

Will it stay free?

FlowKey is free during the beta. After that, we're planning a one-time price — no monthly subscription, no usage caps. Beta users will get a permanent discount.
