A deck is one HTML file. Edit it with a Figma-style editor, or let an agent edit the file. No proprietary format, nothing to build.
Edit them visually in your browser, present with a speaker view, and let your own coding agent fix slides from comments.

A deck is one HTML file. Edit it with a Figma-style editor, or let an agent edit the file. No proprietary format, nothing to build.
Speaker view with notes, a timer and a next-slide preview, an audience window, and a phone remote.
Decks are private until you share them. Send a link, protect it with a password, or export HTML and PDF any time.
Leave a comment on any element or area of a slide. A coding agent you connect (Codex, Claude Code, or anything that speaks MCP or runs a shell command) picks it up, edits the deck and replies. You can revert its edit with one click.


The engine, the editor and the command line tools are open source under the MIT license, so your decks keep working long after any service is gone. Read the code, file an issue or run it yourself on GitHub.
