About

Junie is JetBrains' AI coding agent, built to be cost-efficient. It plans with a powerful model and implements with a faster one, so you spend fewer tokens per task while getting the same quality. On the independent SWE-Rebench benchmark, Junie resolves more real-world coding issues than other leading agents, at a lower cost per task. Junie supports the latest models from major frontier labs on day zero, so you're never waiting on integration work to use what just shipped. It works with almost any model you choose, inside IDEs like IntelliJ IDEA, directly from the terminal, or from GitHub and GitLab issues and merge requests. A human stays in the loop. Junie asks for approval before risky actions, and you can redirect it mid-task instead of starting over. Teach Junie your team's coding standards, naming conventions, and review process, and switch from another AI coding agent in seconds with no extra setup.

About

Slack Code is a collaborative coding experience that brings teammates and AI agents together to build software in the open. Mentioning an agent can start a temporary code channel for a specific task, giving the team a dedicated place to follow the work, provide direction, review changes, and approve the result without cluttering regular channels. Agents begin with the conversations and knowledge they are permitted to access, helping them work with useful team context from the start. Users can describe what they want built and let an agent produce working code while everyone follows along, weighs in, and decides what ships. Code channels archive automatically when the task is complete, while their context remains searchable for future reference. Agents are organized in the Agents tab, where users can check sessions, monitor live status, and see when input is needed. Smarter threads create clearer titles so previous work is easier to find and resume.
