CapMouse

CapMouse puts captions on real life.

Whether you're at a meeting, a doctor's appointment, a family dinner, or just trying to follow a podcast through your speakers, CapMouse transcribes what's being said into clear, large text — right on your iPhone, in real time.

BUILT FOR PEOPLE WHO RELY ON READING Designed with deaf and hard-of-hearing users in mind. Big readable text, follow-live scrolling, jump-to-live for when you scroll back. No accounts, no setup screens, no friction.

DIALOGUE MODE — TWO-WAY CONVERSATIONS Quickly switch between hearing someone speak and typing your reply back. Quick Phrases let you respond instantly with common phrases. On supported devices, CapMouse even suggests natural responses to what was just said.

STAYS ON YOUR IPHONE. ALWAYS. Everything is processed on-device using Apple's built-in speech recognition and on-device AI. Audio is never sent to any server — not Apple's, not ours, not OpenAI's. The AI reply suggestions on iOS 26+ run entirely on Apple's on-device language model; CapMouse never uses Private Cloud Compute and never sends your text anywhere. No accounts, no cloud, no analytics, no telemetry, no third-party services. CapMouse cannot read your conversations because they never leave the device they were captured on.

HISTORY WHEN YOU WANT IT Save transcripts of important conversations. Delete them when you don't. You're in control.

WHAT'S DIFFERENT ABOUT CAPMOUSE Most live-caption apps either send your audio to a server or want a subscription. CapMouse does neither. It uses the same on-device speech recognition Apple ships with iOS, presented in a layout designed for reading first instead of listening.

CapMouse is built by one person, for the deaf and hard-of-hearing community. If something's not working for you, tell us — we listen.
