# About Crawler
Crawler interviews you adaptively, builds one structured Knowledge Core that separates verified facts from positioning, and publishes it in human- and AI-readable formats (llms.txt, Markdown and JSON endpoints). Creating and previewing is free; hosting a published Presence is the paid step. Crawler measures what it can observe itself — reads of your published Presence files and Crawler tool interactions — and never claims access to private ChatGPT, Claude, Gemini or other assistant conversations, and never guarantees rankings, indexing, citations or mentions by external AI systems.

## Positioning and story
### Why Crawler exists

Assistants answer questions about you from whatever they can find. Crawler gives them one maintained, owner-approved source instead of scattered fragments.
