Cowart
A native infinite-canvas widget plugin for Codex, built on tldraw, for sketching ideas, annotating images, and generating and iterating images, HTML, and slide decks with Codex.
Cowart is a native infinite-canvas widget plugin for Codex. Built on tldraw, it opens directly inside Codex through an MCP widget rather than a browser, and it persists its canvas pages and image assets in the current project's own folder rather than inside the plugin's repository.
On the canvas, a user can create AI image frames that generate or replace an image from a prompt and reference images at the frame's position and aspect ratio, create widescreen AI HTML frames that generate a runnable single-file HTML page from a prompt and embed it for further editing, and combine images and HTML into AI Slides presentations with thumbnail previews and full-screen playback. Annotated screenshots can also be submitted so Codex generates a cleaned-up new image next to the original, and a bundled MCP tool lets Codex read the current selection, save the canvas, or insert images and HTML into it.
