CaptionStrip

Live captions on your Stream Deck. Use it for your AI's voice, or for anything your Mac plays.

AI voice mode captions only the Claude, ChatGPT, Codex and Perplexity desktop apps. Their words scroll across your Stream Deck as they talk, and music or videos in the background stay out of the captions. Press Replay to read the last answer back word by word.

Or caption all Mac audio: podcasts, calls, videos and streams. You can also name your own apps.

Stream Deck + and + XL: captions across the whole touch strip

Stream Deck Neo: the live line on the Infobar

Any Stream Deck: captions across a row of keys

Caption Button keys: captions on/off, Replay, Clear

Private by design: speech is transcribed on your Mac by Apple's on-device recognition. Nothing is recorded, saved or uploaded.

Works with: macOS 13 or newer only (no Windows yet). AI voice mode works with the desktop apps only. For voice mode in a web browser, choose "All Mac audio". The first time you use it, macOS asks you to allow Speech Recognition and Screen & System Audio Recording. Only sound is used; your screen is never captured.

First release. Live captions on your Stream Deck for your AI's voice (Claude, ChatGPT, Codex and Perplexity desktop apps) or all Mac audio, with Replay and Caption Button keys. Transcribed on your Mac with Apple's on-device recognition; nothing is recorded or uploaded. macOS 13 or newer.
