JetBrains AI Assistant brings AI chat, code generation, and agents into IntelliJ IDEA, PyCharm, WebStorm, and the rest of the JetBrains IDEs. Its bring-your-own-key support takes OpenAI-compatible custom endpoints with your own API key, no JetBrains AI subscription required. Point it at Opper's gateway and your IDE runs on any of 700+ models with one key and a choice of region.
