Tunnel.ai

Works in the tunnel.

Tunnel.ai turns your voice into text entirely on your Mac. No internet, no cloud, no subscription. Your audio never leaves the device.

What it does

• Tap once, talk, tap again — your words become a note.
• Confidence highlighting: unsure words show in orange; click to correct.
• Custom dictionary and vocabulary biasing for names and jargon.
• Audio kept locally, so you can re-transcribe any time.
• Edit, copy, share and search your transcripts.

Requirements

A Mac with Apple silicon (M1 or later) and macOS 14 or later. The transcription model downloads once on first launch, then everything works offline.
