Free accessAsk Brave
Ask Brave brings an AI conversation interface into Brave Search, combining synthesized answers with webpages and other search results. You can start from a normal search and continue in the Ask view. It works in any supported browser, so you can try the service without installing the Brave browser first.

It is useful for exploring what studies say about a question, tracing citations, and comparing evidence across a field. Basic paper search is freely available, while deeper synthesis, study snapshots, and more intensive research modes have separate usage allowances.
