Yap Studio

The video editor you never have to learn.

For people with more to say than time to edit. 30 card types. Every cut checked. No timeline.

Drop in your raw takes, stumbles and all. An agent in Claude Code, the Claude app's Code tab, Codex or Cursor cuts the dead air and the restarts, adds your captions, cards, B-roll and music, and checks the video before you see it. You leave notes from your phone, and the next version follows them.

Yap Studio is an open-source add-on for HyperFrames that edits vertical and horizontal videos on your own computer. It is for people who talk to a camera and would rather not spend the evening in an editor. There is no timeline to drag. A page in your browser walks you through each video, and the notes you approve become taste rules, so the next video starts closer to how you like it.

Your video files stay on your computer. Still frames from pinned notes and contact sheets of your clips go to Anthropic in Claude Code and the Claude app's Code tab, or OpenAI in Codex, along with the transcript, your notes, the project files your agent reads and command output, as part of your agent session. On personal ChatGPT plans, OpenAI may train on it unless "Improve the model for everyone" is off. In Cursor, the same data goes to Cursor (Anysphere) and the company running your chosen model; Privacy Mode stops training. ElevenLabs, WaveSpeed and Pexels get only what they need, and only if you turn them on. Notes about problems with the tool stay on your computer until you agree to share them.

If you build software, the engine is Python with a command line. Skip to For developers.

Three steps, then you talk

You need a Mac with macOS 14 or newer and about 10 GB free on a local disk. Your agent runs setup one step at a time and asks before each install. On a Mac, it uses Homebrew and offers to install Homebrew first if needed.

1. Download yap-studio-workspace-<version>.zip from the latest release and unzip it into a local folder, not a synced one.
2. Open that folder in one of the apps below and say "set me up". The first setup downloads the speech model (about 2.5 GB) and the video renderer, then opens Yap Studio home in your browser.
3. Choose what you're making, add your footage, pick your look on a still from your own take, and press Make my video.

• Claude Code in Terminal: change to the unzipped folder, run claude, and sign in once with /login.
• The Claude app: click Code, choose Local, then Open folder and pick the workspace. Sign in on a paid plan.
• Codex in the ChatGPT app: choose Codex, add a project, then Use an existing folder. Trust the folder once. Or install the Terminal CLI, run codex in this folder, and choose Trust and continue.
• Cursor: File > Open Folder, then Cmd+I. Use Agent mode on this Mac, not a cloud agent. Privacy Mode is suggested.

In your chosen app, type set me up. Chat apps (Claude Chat, Cowork, ChatGPT chat) can't edit these videos.

In Codex and Cursor, press the button on the page, then tell the agent in chat so it can check for your choice. Claude Code can listen in the background.

After that, you watch the story cut and then the finished video, leave notes on any moment, and approve the version you keep. docs/home.md explains how the page and the agent work together.

You talk. The agent edits. You comment.

These are real screens from a full run on synthetic footage: a photo of a generated sample presenter with a slow push, reading a short script in the Mac's built-in voice.

The same pages work on a phone over the same Wi-Fi or Tailscale. Anything paid, such as generated music, still goes through your agent in chat, and your agent asks first.

Made with Yap Studio

• How I use Tailscale: a talking-head video, edited end to end by the agent.
• A cold plunge build: the first voiceover test, made from footage that sat in a camera roll since 2023.
• The launch teaser.

What goes into the edit

• A story cut from your own words. Fillers, restarts and long pauses come out, and every join is checked for clicks and clipped words.
• Captions in your look: font, colours, highlight, one word at a time or whole phrases.
• Titles and more than two dozen kinds of cards (stats, quotes, checklists, steps, charts), each timed to the words it is about.
• Big words behind your head, cut around your outline, or a page, screenshot or clip behind you for a stretch (macOS).
• B-roll from your own photos and clips, cut in while you talk about them. Stock clips only if you turn them on, and only the ones you approve.
• Music from your own track, or composed with your ElevenLabs account (affiliate link) once you approve it.
• Sound effects on cuts, cards and counts, kept under your voice. They are made on your computer with no account, or come from your own ElevenLabs kit.
• Captions and cards that stay off your face. When faces were measured, a final that covers them fails its chec
