Humata

Humata is an AI knowledge base for your documents. Upload PDFs and other files, then ask questions across all of them and get fast answers with citations that highlight exactly where in the source each answer comes from.

It is used by researchers, students, legal and business teams to analyse long or technical documents, summarise reports, compare papers and find specific facts without reading everything. Teams can share a workspace so everyone can query the same document library, and an API lets companies add Humata's document Q&A to their own products.

Good fit if you: work with many long documents and need trustworthy answers you can verify.
Less ideal if you: need a general chatbot for open-ended questions not covered by your files.

Pricing: free plan to try it; paid plans for students, experts and teams add more pages, questions and collaboration.
