About this app

AI PDF Reader, Editor & Sign is the all-in-one PDF reader, PDF editor, and AI document assistant for work, study, and everyday files. Open a PDF, read it comfortably, search for details, chat with the document, edit text, fill forms, add a signature, redact content, and organize pages—all in one simple PDF app.

PDF READER FOR WORK, STUDY & EVERYDAY DOCUMENTS

Open documents from your phone, email, cloud storage, or file manager. Read reports, contracts, manuals, textbooks, forms, and notes with tools that help you stay focused:

• Search inside a PDF to find words and passages quickly
• Save bookmarks for important pages
• Jump directly to a page instead of scrolling through a long file
• Choose vertical or horizontal scrolling and use page snapping
• Use reading modes, eye-protector mode, and keep-screen-on controls
• Turn on auto-scroll for hands-free PDF reading
• Listen with read aloud for a page, selected text, or a readable document
• Print or share a PDF when you are ready

CHAT WITH PDF USING AI

Ask questions about the document you are reading. AI PDF chat helps you explore information in contracts, reports, research papers, guides, and study notes without manually searching every page. Use follow-up questions to understand a topic, clarify a section, or find the details you need from your PDF.

AI PDF SUMMARIZER

Turn a lengthy PDF into a clear summary. Create concise, detailed, or bulleted summaries to review key points faster. Choose an output language for new AI summaries when you want to read the main ideas in your preferred language. AI features and document allowances vary by plan.

EDIT PDF TEXT, FILL FORMS & ANNOTATE

Make practical edits without moving your document between apps. Edit PDF text, work with editable text blocks, change formatting and fonts, and fill PDF forms from your phone or tablet. Mark up a document with the tools you need for review:

• Highlight text and important passages
• Draw freehand, lines, arrows, rectangles, and circles
• Add annotation symbols and shapes
• Add text, images, and date stamps
• Apply text or image watermarks, including centered, tiled, or diagonal placement
• Save a draft while your PDF is still in progress

SIGN PDF & COMPLETE FORMS

Draw a signature with your finger or stylus, or import a signature image. Place, resize, and save your signature on a PDF, then share the completed file. Sign PDF documents, complete forms, and prepare contracts or approvals without printing and rescanning paperwork.

REDACT PDF CONTENT

Cover sensitive information before you share a document. Use colour redaction or choose blur and pixelate effects by plan. Review the finished PDF before sending it to the intended recipient.

MERGE, SPLIT & ORGANIZE PDF PAGES

Merge PDF files into one document, split a PDF into separate files, extract selected pages, and reorder pages when your documents need a cleaner structure. These PDF organizer tools are useful for combining attachments, separating sections, or preparing only the pages someone needs.
