Crawl what matters.
PageBrain maps your entire site in minutes — every page, link, and meta tag — while extracting 100+ data points that traditional crawlers miss. From semantic embeddings to LLM chunking, you get the full picture of how both search engines and AI models see your content.
Built for the modern web.
JavaScript-rendered, configurable, and fast. PageBrain handles everything legacy crawlers miss — SPAs, dynamic content, custom URL rules — and gets you to your data without the setup overhead.
JavaScript rendering. Fully render client-side pages with a headless browser. SPAs, lazy-loaded content, and dynamic elements are crawled exactly as a real user — and a real bot — would see them.
Configurable crawl rules. Define depth limits, URL inclusion/exclusion patterns, subdomain handling, and custom crawl scope. Crawl exactly the pages that matter and skip everything that doesn't.
Instant issue discovery. Issues are surfaced, categorized, and prioritized the moment a crawl finishes. No post-processing step, no waiting — start acting on findings while the crawl is still warm.
Modern, intuitive UX. Crawling shouldn't feel like using spreadsheet software from 2009. PageBrain is designed so you can discover issues, organize data, and get work done fast — without a manual.
Extractions that go further.
Beyond titles and status codes — every crawled page is embedded for semantic analysis, simulated for LLM chunking, and scored for both traditional SEO and modern GEO signals. All in one crawl.
Combined SEO + GEO analysis. Every crawl captures both traditional SEO signals and modern GEO data in a single pass. No toggling between tools — your entire search visibility picture in one place.
Semantic page embeddings. Every crawled page is automatically embedded and indexed. Find near-duplicate content, topical clusters, and content gaps that keyword matching misses.
LLM chunking simulation. See exactly how large language models would parse, chunk, and tokenize each page. Understand how your content is being interpreted by AI search engines — and optimize accordingly.
Innovative extractions. Reading level, content density, entity mentions, semantic structure, internal link context, and AI-readiness signals — data points that legacy crawlers don't touch.
Every page. Every signal.
The full crawl table puts 100+ data points per page in one filterable view. Sort by issue type, drill into any page, and go from discovery to action without switching tools.

See how LLMs read your content.
The LLM chunking view breaks each page into the segments a language model would process — showing token boundaries, chunk sizes, and how your content structure translates to AI understanding.
