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.

$ Hey team, let's move the standup to 3pm tomorrow and add the Q2 roadmap to the agenda.|

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.

1

You press Option+Space

Airtight begins capturing audio from your microphone.

2

Audio is recorded to a local WAV file

16kHz mono PCM, stored in ~/Library/Application Support/Airtight/.

3

Speech model processes the audio

Runs entirely on your CPU/GPU via Metal. No network calls.

4

Optional: A local AI model refines the text

Still no network calls.

5

Text is copied to your clipboard

And optionally auto-pasted into the active app via accessibility API.

6

Audio file is kept or deleted

Your choice. Either way, it never left your machine.
