Demo videos recorded by your coding agent

How it works

1. You copy a prompt from tday. It carries one install line, which adds tday's MCP server to your coding agent, and the sentence to ask it.
2. Your agent runs a safety check and tells you where the demo's data will live and which outside services your app's server can reach.
3. It starts a second instance of your app on a free port with throwaway, seeded data, and records one narrated line at a time: what to say, and the clicks and typing that line covers.
4. It writes a review page on your machine. A possible secret on screen or in a line blocks the upload. A clean take uploads.
5. tday voices each line, adds the cursor, camera, captions, cards and music, and renders the demo. It opens in tday's editor, where you can change the narration, the timeline and the style.

What you need

• A coding agent that supports MCP: Claude Code, Cursor, Codex or another MCP client.
• Your app's repo on macOS, Linux or Windows (WSL2), with Node.js 18.17 or later and ffmpeg.
• Google Chrome, or Playwright's Chromium, for a web app or a terminal tool. iPhone, Android and Mac apps need more tools.
• A way to give the demo throwaway data, such as a seed script with a local or branchable database.
• Test keys for payments, email and the other services your app's server calls.

What it does not do

• It does not record by itself when you push or merge. Your agent records when you ask it to. On Pro and above, tday lists the demos a merged pull request may have put out of date, and you ask your agent to record them again.
• It needs your app running from its repo on a developer's machine. The exception is Enterprise, where tday can also record in the cloud.
• One take holds at most 40 narrated lines and 10 minutes.
• The guard that blocks outside requests covers the app's window in web and Electron demos, not your app's server. A server started with live keys can still send a real email or charge a real card.
• The voice is paid from your plan's monthly credits. With too few left, the demo is made without a voiceover and shows short step notes instead.
• The Free plan keeps 5 saved demos, and its shared and downloaded demos carry a tday badge.

When something else fits better

• You want a quick, unscripted recording of yourself talking over your screen. A screen recorder does that in one sitting. A tday demo is planned line by line.
• You want an interactive tour that viewers click through themselves. tday makes videos.
• Nobody on your team uses a coding agent, or the person making the demo cannot run the app from its repo.
• Your app cannot run on a developer's machine with throwaway data, for example because it only works against production.
