Petal turns PDFs and research files into a library you can query with sourced answers, citations, and team annotations. Upload documents to the cloud drive, chat with a single file or multiple papers, and export citation lists without leaving the workspace at cite.petal.org.

Compared with a general chatbot, Petal anchors replies to documents you upload and highlights where each answer came from. It also bundles a reference manager, citation generator, browser capture plugin, and multi-document AI Table filters that general note apps usually lack.

Researchers, R&D teams, and faculty groups use Petal to scan technical PDFs, share annotated libraries, and compare studies across collections. The homepage cites 20,000+ researchers and lists MIT, UT Austin, Caltech, and Intuit logos among its users.
