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.

A private, visual AI space to save and remember anything — no folders, no tagging
Save notes, links, quotes, images, articles, PDFs and videos in one click, and let mymind categorize them automatically instead of building folder structures.
Find saved items by color, brand, keyword or date. Image text recognition even lets you search words that appear inside screenshots, memes or handwriting.
Images get tagged automatically, and Mastermind members get paragraph summaries of articles, web pages and PDFs so old saves are still useful months later.
Smart Spaces auto-group saves around a search, theme or tag, while Same Vibe builds a mood board from images you already saved with a similar look and feel.
