Your AI knowledge base that remembers everything you save
Capture YouTube videos, podcasts, PDFs, articles, blog posts and personal notes from the browser, desktop app or mobile without copying text by hand.
Long-form sources are condensed into short readable or listenable summaries, with timestamped key moments for video and audio content.
Ask questions against your saved library using ChatGPT, Claude, Gemini, Grok, DeepSeek or other supported models, so answers stay grounded in your material.
Related ideas across items are linked automatically and mapped in a knowledge graph so you can follow a topic from one source to the next.

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.
