I used to spend a lot of time on Google and stack, now I ask phind more often than not, which violates information for me.

Try phind.com, it’s free for now, and uses gpt-3.5 unlimited or gpt-4 limited to 25 requests per… 4 hours I think. Never ran out. It’s specialised for devs. So far the output is the best of bing AI, and Copilot chat that I’m testing.
