All-in-one online PDF editor with AI helpers for reading, summarizing, and generating documents
Edit text, fonts, sizes and colours directly in the document, insert images, add page numbers, watermarks and Bates numbering, rotate, extract or rearrange pages, and split or merge files.
Convert between PDF and Word, Excel, PowerPoint, CSV, JPG, PNG, HEIC, EPUB, Markdown and text, including bank-statement-to-spreadsheet and PDF comparison workflows.
Type, draw or upload a signature, request signatures by email, add password protection, black out sensitive content and make flat or scanned forms fillable.
Chat with a PDF to ask questions about its contents, summarize a long document into key points, generate a formatted PDF from a description, or have AI populate a form automatically.

AI-powered document scoring, evaluation and verification
Upload, analyze, and retrieve documents in a few clicks, with AI reviewing each file against your approved headers and templates instead of relying on manual spot-checks.
Generate consistent numerical scores for every submission so reviewers and stakeholders can compare documents objectively rather than relying on gut feel.
AI writes the reasoning behind each score, giving you an audit trail that explains why a document passed or fell short, which is especially valuable in compliance contexts.
Standard and premium plans condense long documents into digestible summaries, so reviewers can triage a large batch quickly before reading in depth.
