Your voice. Your Mac. Nothing leaves.

No account needed. Instant download. Works offline in 30 seconds.
Recording
Speak clearly into your mic
Can you send the proposal by EOD?
Same message. 150 WPM vs 40 WPM.
You think faster than you type.
The average knowledge worker types 40 words per minute. You think at 150. Every email, every report, every message, you're bottlenecked by your fingers. And most dictation tools send your audio to someone else's server just to bridge that gap.
Airtight removes both problems. Dictate 4x faster than typing, and every word stays on your Mac. No upload. No server. No compromise.
The cloud way
The Airtight way

Press Option+Space
Anywhere on your Mac. In any app. The hotkey is fully customizable.
Speak naturally
No special commands. No pauses needed. Talk like you normally would.
Text appears instantly
Transcribed, refined, and pasted right where your cursor is. 4x faster than typing.
We didn't build a privacy policy. We built a wall.
Here is exactly what happens to your audio. Every step. On your machine. Verify it yourself.
You press Option+Space
Airtight begins capturing audio from your microphone.
Audio is recorded to a local WAV file
16kHz mono PCM, stored in ~/Library/Application Support/Airtight/.
Speech model processes the audio
Runs entirely on your CPU/GPU via Metal. No network calls.
Optional: A local AI model refines the text
Still no network calls.
Text is copied to your clipboard
And optionally auto-pasted into the active app via accessibility API.
Audio file is kept or deleted
Your choice. Either way, it never left your machine.
