Master Your Documents with Intelligent Precision
The blazing-fast Android PDF Reader and document workspace with Vexari AI Assistant, instant OCR, signature management, and local-first privacy.
Unified Document Power
Built from the ground up for students, researchers, and professionals.
Persistent Reading Position
Never lose your place again. Reading position, bookmarks, and zoom factors survive app close, Android process death, and device reboots independently for every document.
Vexari AI Assistant
Ask questions directly against your documents. Generate concise executive summaries, generate multi-choice study flashcards, and translate document chapters in real-time.
Local-First Privacy
Your documents stay on your device. We do not upload your personal files to the cloud unless you explicitly request cloud processing for specific AI tasks.
Camera Scanner & OCR
Capture physical documents with automatic OpenCV edge detection and perspective correction. Extract searchable text offline with on-device ML Kit OCR.
Form Filling & Signatures
Fill standard AcroForm interactive fields, checkboxes, and text inputs with full PDFBox compatibility. Sign contracts with your custom smooth vector signature.
14+ Power PDF Tools
Merge multiple files, split pages, compress file size, crop margins, reorder pages, add watermarks, password-protect files, and extract text without third-party services.
