AI PDF Reader, Edit & Sign

Read, understand, edit, scan and sign PDF files on your phone — with AI that runs on your device, not on someone else's server. AI PDF Reader & Editor is a complete PDF toolkit. Open any PDF, Word, Excel, PowerPoint or text file, ask questions about it, change the words on the page, sign it, convert it and share it. Your documents never leave your phone. ★ AI THAT READS WITH YOU • Summarise a long document into its key points • Ask a question about a document and get an answer from its own text • Runs on your device — your documents are never uploaded to be processed ★ GENUINE PDF TEXT EDITING Tap a line of text and replace it. The app rewrites the words in the page's own content stream and matches the original font, size and colour — it does not paste a white box over the old text and hope. Tables and columns keep their layout. ★ READ EVERY DOCUMENT • PDF, Word (DOC, DOCX), Excel (XLS, XLSX), PowerPoint (PPT, PPTX) and TXT • Fast, smooth page rendering built for large files • Night mode, page jump, zoom and search inside a document • Favourites and a recent list so you can pick up where you left off ★ SMART CAMERA SCANNER • Turn paper into a clean, sharp PDF • Automatic edge detection and perspective correction • Filters for whiteboards, receipts and printed pages • Multi-page scanning into one document ★ CONVERT ANYTHING • PDF to Word, PDF to Image • Word to PDF, PowerPoint to PDF, Image to PDF ★ EDIT AND ORGANISE • Merge several PDFs into one • Split one PDF into many • Reorder, rotate and delete pages • Compress a PDF to a smaller size • Annotate and draw freehand • Add text anywhere on a page ★ FILL AND SIGN • Draw your signature or import a photo of one • Save signatures and reuse them in one tap • Place and resize a signature anywhere ★ TRANSLATE OFFLINE Translate a PDF into another language on your own device using Google ML Kit. The language pack downloads once, then works with no network. The text being translated is never sent anywhere. ★ PRIVATE BY DESIGN • No account required • No document ever uploaded for processing • AI, conversion, editing and translation all run locally • A recycle bin holds deleted files so a mistake is recoverable ★ BUILT FOR PHONE AND TABLET Material Design 3 interface, light and dark themes, and layouts that use the whole screen on a tablet.
