Key features
- Answers with inline citations to web sources
- Follow-up questions in a conversational thread
- Deep research mode for longer reports
- File uploads and organized spaces
- Choice of models on paid plans
Who it’s for
Anyone who wants quick, sourced answers to research questions, and professionals doing background research.
Pricing model
Free plan with limits; paid plans unlock higher usage and advanced features. Prices and limits change often, so always confirm on the official website.
Things to consider
- Always open the cited sources for important facts; summaries can misstate them.
