Everything needed to use IA Checker with confidence: quickstarts, detection methods, file support, writing workflows, word credits, privacy and the developer API preview.

## Start here

New to IA Checker? Open [Get started](/docs/get-started) for the product map or follow the [Quickstart](/docs/quickstart) to run a first text or image check.

1. **Choose the source**: Text, a public URL, a document or an image.
2. **Run the focused workflow**: Use the detector or writing tool built for that source.
3. **Read the evidence**: Move from the verdict into the sentence, model, forensic and provenance details.

## Built for people and AI assistants

Every published documentation page has a plain Markdown twin generated from the same typed source. The HTML page, table of contents, search index, sitemap, `llms.txt` and full assistant corpus therefore describe the same product state.

- Use **Copy for LLM** to copy the current page as Markdown.
- Use **View as Markdown** to open the crawlable `.md` twin.
- Use `/llms.txt` for the concise site index and `/llms-full.txt` for the combined public corpus.
