@erictgrubaugh I personally tested:
• ChatGPT 4.x
• Gemini Advanced
• JetBrains IA Assistant
None of them produce very accurate results; most of them bring up things that do not exist or do not work. More often than not, you waste more time trying to fix the hallucination than if you were doing it yourself.
The JetBrains IA Assistant gives me the best results because it automatically contextualizes itself in the current block of code or the file you are working on.
