You know that feature in JetBrains (and possibly other) IDEs that highlights non-errors, like code that could be optimized for speed or readability (inverting ifs, using LINQ instead of a foreach, and so on)? As far as I can tell, these are just heuristics, and it feels like the perfect place for an “AI HUD.”

I don’t use Copilot or other coding AIs directly in the IDE because, most of the time, they just get in the way. I mainly use ChatGPT as a more powerful search engine, and this feels like exactly the kind of IDE integration that would fit well with my workflow.
