About Petal
Petal combines a cloud drive for documents with an AI chat that answers questions from the files you upload or link, citing the passages it used. It extracts metadata automatically, and a built-in notebook helps summarise, translate and draft new text from your material.
Teams can collaborate and share documents in one workspace. It is used by researchers, faculty, students and corporate R&D groups who work with technical papers and want answers grounded in their own sources.
