Decks, the slow way

LLMs are great at structure & words. But turning what they write into slides that look like your brand still means copying, pasting & nudging boxes around.

Markdown in, on-brand slides out

ChatPPT is a Mac app that turns Markdown from your favourite LLM into beautiful, on-brand slides in seconds. Ask your model for a deck, paste it in, present.

Visual to comeScreen recording: from Markdown to a finished deck

Made for LLMs

The format is designed around how models write, so the decks they draft come out right the first time. How it works, and the brand themes behind it: more on this soon.

A slide: instant & beautiful slides, perfect for Claude Code, Codex, Cursor & more — Made for coding agents, with your own brand coming soon

A free Mac app

ChatPPT is free on the Mac App Store, and it all runs on your Mac: no cloud, no account, no tracking. Why a Mac app, and what building one taught me: more on this soon.
