HTML is the new
presentation tool.
Your coding agent builds slide decks and motion videos as one HTML file, then edits them live while you point and comment.
installAdd it in one command.
It installs as an agent skill. Point your coding agent at it and start building.

It’s added to your coding agent. Then just ask: “make me a deck about…”
Point at a slide. Type a change.
The skill opens your deck in a dependency-free browser editor. Double-click any text to edit it, single-click an element to leave the agent a note, and the deck live-reloads as edits land.
The slides editor: your deck on the left, your requests to the agent on the right.
Not just slides. Full motion videos.
The same skill builds self-contained HTML videos: one file, one master clock, no export step. Open one and the editor becomes a video studio with play, frame-accurate scrubbing, speed control, and comments pinned to the exact timecode.
The video editor: a transport bar and scrubber, with every comment pinned to its timecode (“tighten this at 0:13.”)
Decks or videos, one loop.
Both run the same content-first path. The agent settles the words, locks a look, rolls it out, and then stays in the live loop with you.
Any style you can describe.
Tell your agent the look you want and it designs one from scratch. Or start from one of ten committed templates that ship with the skill:
…plus Warm Paper, Swiss Grid, Botanical, SaaS Pitch, and Vintage Press. See all ten →
Give your agent an HTML deck & video editor.
Install it, use it, keep it current.
