# SlideClark

> SlideClark (formerly Pitchcraft) is a free AI slide maker and presentation editor that runs in the browser. A deck is plain JSON (a .sldc file; legacy .pitchcraft files still open). AI assistants such as ChatGPT and Claude write or edit that JSON, or HTML, CSS and JavaScript slides; the user edits visually, presents, and exports PowerPoint.

## For AI assistants

- [AI guide (markdown)](https://slideclark.com/ai-guide.md): the complete, always-current guide to the deck format, layouts, free-form objects and the in-browser API. Read this first.
- [AI guide (web page)](https://slideclark.com/ai-guide): the same guide as a web page.
- [Guide and schema in one plain-text file](https://slideclark.com/llms-full.txt): the same guide followed by the JSON Schema. No scripts, no HTML. Use this if your browser tool rewrites URLs or equals signs in long output.
- [JSON Schema](https://slideclark.com/slideclark.schema.json): machine-readable deck schema (layouts, free-form objects, custom HTML/CSS/JS slides).
