Work across 1,000 documents

A Dossier is a project workspace with up to 1,000 files such as contracts, PDFs, emails, Excel sheets and PowerPoint decks, for example for a due diligence, ongoing proceedings or your firm’s templates. You can ask questions across all files, get answers with numbered sources and change many documents at once.

You can add Word documents, PDFs, Excel and PowerPoint files and Outlook emails (.eml and .msg) of up to 100 MB each, or link files from SharePoint without uploading them again.

The Dossier chat searches all files at once and answers with numbered sources. Each source shows the file name and the exact passage, so you can check every statement.
