What it does

This is a JetBrains IDE plugin that embeds ChatGPT directly into IntelliJ IDEA, PyCharm, and the rest of the family. You can chat, ask questions about your codebase, and get AI-generated fixes without switching windows or losing your flow.

The interesting bit

The plugin treats the IDE as a first-class citizen rather than a dumb host. Alt-D toggles diff mode so you can review AI edits side-by-side; Alt-Enter surfaces quick-fixes for errors inline; and typing @ lets you pull specific files into the conversation context. It is the small integration details that make the difference between “ChatGPT in a panel” and “actually useful.”

Key highlights

• Diff mode (Alt-D) for reviewing AI-generated code changes directly in the editor
• Quick-fix errors with Alt-Enter, including runtime exception explanations
• Codebase-aware queries that understand your project structure
• @ mentions to include specific files in the prompt context
• Installable from the JetBrains Marketplace; GPL v2 licensed with an unusual non-compete clause

Caveats

• The README is thin on technical architecture and API details; it is unclear whether this calls OpenAI directly or proxies through a custom backend
• The license adds a specific restriction against using the code to build competing JetBrains Marketplace plugins, which may affect forks
• Not an official OpenAI product; the author explicitly disclaims responsibility for any damage

Verdict

Worth a look if you live in JetBrains IDEs and want tighter ChatGPT integration than a browser tab. Skip it if you need transparency about how your code is sent to the model, or if the license restrictions make you nervous.
