# Yap

> Yap is a macOS app where your slides composite over your live camera, so you present like a streamer and record one take that becomes a 16:9 video and a 9:16 Reel. Built on Apple frameworks (Vision person segmentation, on-device Speech, Core Image + Metal); the AI deck-builder is bring-your-own Anthropic key.

## Docs

- [Yap](https://cadence.host/yap/docs.html#overview): Yap is a macOS app where your slides composite over your live camera. The create, present, record loop, and what you need to start.
- [Install Yap](https://cadence.host/yap/docs.html#install): Download the DMG, drag Yap to Applications, and grant Camera and the other permissions as Yap asks for them.
- [Slides](https://cadence.host/yap/docs.html#slide-anatomy): A slide composites your camera with one media item, one line of text, and one entrance effect. Layouts, text styles, media types, and build-on-previous.
- [AI deck-builder](https://cadence.host/yap/docs.html#ai): Describe a deck in plain language and Claude builds it live. Free credits to start, then add your own Anthropic key for unlimited use.
- [Text effects](https://cadence.host/yap/docs.html#effects): Fourteen entrance effects for your slide text. What you see live is exactly what exports.
- [Present](https://cadence.host/yap/docs.html#present): Enter present mode, choose a window, full screen, or a projector, switch layouts live, and keep a private presenter panel. Includes green screen.
- [Live captions](https://cadence.host/yap/docs.html#live-captions): On-device subtitles of your speech, pinned to the bottom of the stage. A per-slide toggle.
- [Record](https://cadence.host/yap/docs.html#record): Two recorders. Record Session for a take you reframe into 16:9 and 9:16 later. Record This View for a quick baked clip of exactly what is on screen.
- [Export](https://cadence.host/yap/docs.html#export): Record once, export a 1920x1080 video and a 1080x1920 Reel from the same take. Each is reframed, not cropped.
- [Files](https://cadence.host/yap/docs.html#files): Decks save as portable .yap files, autosave continuously, keep version history, and carry their recordings with them.
- [Privacy](https://cadence.host/yap/docs.html#privacy): Only your AI prompt and slide text ever leave your Mac. Camera, photos, and recordings stay local.
- [Troubleshooting](https://cadence.host/yap/docs.html#troubleshooting): Fixes for the common issues: black camera, missing captions, AI, recording, and green-screen quality. Plus quick answers.
- [For agents](https://cadence.host/yap/docs.html#for-agents): Machine-readable docs for AI agents: llms.txt, the full Markdown, and the feature manifest.
