AI research workspace for searching, reading and connecting papers
Search a corpus of hundreds of millions of papers by meaning, with new content indexed continuously from thousands of journals.
Ask questions of any paper and place multiple studies side by side to spot agreements, contradictions and the bigger picture.
A visual graph maps how papers and concepts connect, helping you find adjacent work you would otherwise miss.
Upload your own PDFs, capture reading notes, and organize everything in a single research workspace.

Save the web, then chat, summarise and write from your sources
A floating save button plus Cmd/Ctrl+Shift+S captures pages, PDFs, videos and tweets, with native-style buttons injected on YouTube, X, Substack and Medium.
Cmd/Ctrl+Shift+K searches every saved link, PDF, tweet and video without leaving the page; Shift+R surfaces similar items in your library.
Ask questions across an entire project and get answers that point to the exact page and passage, so you can verify in one click.
Compare or switch between leading AI models with dual chat instead of stacking several subscriptions.
