The best JetBrains AI extension depends on the job: first-party IDE assistance, an integrated coding agent, or a separate plan-and-verify workflow. Verify support for your exact IDE and version because “JetBrains support” does not mean identical features everywhere.

Current official options include:

Compare native project context, multi-file editing, terminal and test access, permission modes, project instructions, remote-development support, data routing, and change review. Install only from the official Marketplace or provider route and match the publisher identity.
Test each finalist on one read-only explanation and one small reversible edit. Record context accuracy, unrelated changes, test evidence, and reviewer time. The best option is the one that reduces accepted-work time inside your controls.
