Real experience with AI tools

When I first started using AI coding tools — OpenClaw and Hermes Agent — every bug sent me straight to a search engine. I'd paste error messages into Chinese AI models and get back answers that sounded right but didn't work. The suggestions kept piling up. None of them fixed the actual problem.

Then I tried Claude for debugging. The difference wasn't smarter answers — it was better logic. Chinese models would give me a single solution with no explanation. Claude walked through why the error happened, what the fix actually changed, and what I should check if the fix didn't work. That last part saved me the most time.

Chinese AI has improved a lot since then — several generations of models later, the answers are much better. But that experience taught me something: the best AI tool is the one that explains its reasoning, not the one that sounds most confident.
