AI PDF Editor, Reader & Sign

AI PDF Editor & Summarizer is the all-in-one PDF editor, PDF reader, and AI document assistant that lets you chat with PDFs, summarize documents, edit PDF text, sign and fill forms, redact sensitive info, translate content, and merge or split files — all in a single PDF tool. Stop switching between five different apps to read, edit, sign, and understand your PDFs.

🤖 CHAT WITH PDF USING AI
Ask questions about any PDF and get instant, accurate answers from our AI PDF chat assistant. Whether it's a contract, research paper, or textbook, chat with PDF lets you find what you need without reading every page — a smarter way to do PDF question answering.

✨ AI PDF SUMMARIZER
Turn long documents into clear, concise summaries in seconds. Our AI-powered PDF summarizer and document summarizer extracts key points from reports, articles, and study material — perfect for students, professionals, and researchers who need to summarize documents fast.

🌐 AI PDF TRANSLATOR
Translate PDF content instantly with a built-in PDF translator, breaking language barriers without leaving the app.

✍️ PDF EDITOR — EDIT PDF TEXT, DRAW & ANNOTATE
Edit PDF text like a word processor, draw and highlight with a PDF highlighter, add sticky-note annotations, insert date stamps, and apply custom watermarks with our PDF annotation tool and PDF stamp features. Everything you need to mark up and finalize a document.

🖊️ SIGN PDF, FILL FORMS & ADD SIGNATURE TO PDF
Add your signature, initials, or use our PDF form filler to complete PDF forms directly on your phone or tablet. No printing, no scanning — sign PDF documents and contracts in seconds.

🔒 REDACT PDF — BLACK OUT SENSITIVE TEXT
Permanently black out confidential information before sharing a PDF — ideal for legal, HR, and financial documents that need secure redaction.

📑 MERGE PDF & SPLIT PDF FILES
Combine multiple PDF files into one document, or split PDF pages into separate files. Organize your files exactly the way you need.

🎨 CUSTOMIZE WITH PDF WATERMARK & STAMPS
Apply text watermarks like "CONFIDENTIAL," "DRAFT," or "APPROVED," or create your own custom PDF watermark — plus add date stamps in multiple formats.

💎 FREE PLAN + PLUS & MAX PREMIUM
Get started free with daily AI PDF chat and summary credits, standard editing tools, and everyday PDF tools. Upgrade to Plus or Max premium for a much higher daily AI chat and summarizer allowance, advanced PDF editing tools, unlimited sign & fill, and unlimited merge & split — with no ads. (AI chat and summarize limits are higher on Plus/Max, not unlimited — fair-use daily allowances apply.)
