1. ChatGPT (GPT-4): Still the most polished and reliable AI overall.
  2. Grok (xAI): Great at digging into technical content on X (Twitter).
  3. Claude: Ideal for code generation, test writing, and general dev workflows.
  4. Sonar (Perplexity AI): My go-to for real-time research.
  5. Gemini (Google): Mixed feelings here.

Additionally, some tools for grammar check. What about you? What AI tools do you use as a developer, and for what tasks?
