The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.

Cross-platform PDF editing with GPT-powered AI for reading, translating, and signing documents
Edit text and images directly, annotate ideas, add links and watermarks, and use OCR to make scanned PDFs editable — all inside one app instead of switching tools.
Summarise, translate, explain, or chat with a PDF across the entire file, a single page, or a saved page range, so long documents stay manageable and answers stay focused.
Ready-made agents for researcher, contract, resume, finance, and study workflows analyse documents, surface risks and key terms, and suggest improvements.
Convert PDFs to Word, Excel, PowerPoint, or images, merge, split, crop, and rotate pages, and batch-process multiple files in a single pass.
