Ask HN: What AI tools you use often?

Refact.ai as a free copilot alternative

I'm very interested in this space and played with a lot of tools, but i've yet really to manage to have enough use cases for any of them, beyond finding them fun to play with, I feel that a lot of them are just not quite there yet but very close.

Although I am hoping for easier/cheaper GPT 4 access soon, then I might start using it a bit more.
