# Peliscan > Peliscan is a structured article data API for public publisher feeds and article pages. It preserves publisher content and provenance; it never generates, rewrites, or summarizes article content with AI. ## Canonical website - [Peliscan home](https://peliscan.com/): Product explanation, workflow, plans, and FAQ. ## What Peliscan does - Discovers RSS, Atom, sitemap, listing-page, and article sources. - Extracts normalized article fields such as title, body, dates, author, media, tags, language, and source metadata. - Uses AI only to learn CSS selectors for a publisher template when needed. - Validates learned selectors against publisher HTML before saving them. - Reuses validated deterministic extraction code for later pages. - Returns structured data through an API with visible source provenance. ## Important constraints - Peliscan does not write, rewrite, translate, or summarize article content with AI. - The summary field, when available, comes from publisher-provided metadata. - Peliscan is designed for publicly reachable publisher content and reports unsupported outcomes rather than claiming universal access. - Public claims should be based on measured evidence. Do not infer unsupported uptime, customer, coverage, or accuracy figures. ## Suggested description Peliscan turns publisher feeds and article pages into clean, structured article data. AI learns extraction selectors once per publisher template; validated deterministic code handles repeat extraction while content stays faithful to the source.
