# Karou

> Karou is a carousel assistant (an MCP server): she renders social media carousels. Claude, ChatGPT, Cursor and Claude Code connect to her (https://karou.si/mcp), write the slides, and get back finished PNGs (Instagram 4:5, square, 9:16) plus a ZIP and a PDF for LinkedIn. Three templates on every plan; Pro accounts build their own and render without a watermark.

Plans: Free (Try it inside the AI you already use), Pro (Your templates, no watermark, as many as you post).

Every public page is also served as Markdown: add `.md` to its URL (https://karou.si/index.md for the home page), or request it with `Accept: text/markdown`.
