AI-powered document analysis platform that allows users to chat with their documents and knowledge bases to get fully sourced, reliable answers.
Petal is a freemium document analysis platform that lets users chat with their documents and knowledge bases to get fully sourced, citation-backed answers, with pricing starting at free for light use and paid plans from $19.99/month for the Pro tier. Used by thousands of researchers and professionals across academia, legal, and corporate sectors, Petal focuses on multi-document querying — allowing users to upload entire collections of PDFs and ask natural language questions that are answered by synthesizing information across all uploaded sources.
Unlike single-document chat tools such as ChatPDF, Petal is built around the concept of knowledge bases: organized collections of related documents that can be queried simultaneously. Every AI-generated answer includes inline citations linking directly to specific pages and passages in the original documents, enabling one-click verification of any claim. This provenance-first approach makes Petal particularly well-suited for research workflows where traceability and accuracy are non-negotiable.
