Free AI-powered PDF editor, converter and reader for every device
Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.

AI translation companion for text, files and apps, in 100+ languages
Uses generalist AI models rather than translation-only engines, so idioms, slang and implied meaning carry across into the target language.
One-click register switching so a message to a colleague does not read like an administrative letter.
Typos, abbreviations and poor formatting are interpreted rather than translated literally, and cleanup is included.
Click any word to see alternative renderings and swap in the one that fits your style; changes apply immediately.
