A browser that works for you
The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.

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.
