What it is
JetBrains AI bundles AI Assistant (chat and completion) with Junie, a coding agent that uses the IDE's own debugger, semantic index, build configs and test runners. Junie left beta in June 2026 and runs in JetBrains IDEs, a standalone CLI, and GitHub Actions/GitLab CI, with JetBrains-hosted models, your own API keys or local models.
Latest: Junie became generally available in June 2026, adding Plan Mode, agentic debugging and bring-your-own-key support.
What the AI does
- Junie coding agent with Plan Mode
- Debugging through the real IDE debugger
- Junie CLI and GitHub/GitLab CI integration

Pros and cons

- Strong reported benchmark results
- Works with any model, including local ones
- Free tier and free Junie Lite model
- Credit metering drains quickly with heavy agent use
- Best experience is tied to JetBrains IDEs
- Some debugging features depend on IDE version and edition
How it scores
Solid vendor-reported benchmark results and deep IDE integration; value held back by credit metering.
