X.com is where I use it. There is also a grok.com. This is Elon Musk's AI. I also use ChatGPT, Gemini, and the built-in Gramerly. Grok is by far the best. If you are on X, you can use it to analyze posts, and it also does trends. Grok is very good at writing code. I gave it a short program written in a very old version of Basic that they used in the time when computers used tape reels and everything was printed on paper because there were no monitors. I asked Grok to convert it to a bash shell script that I could run on Linux. Not only did it do the conversion, but the script worked right out of the box. I have tried this sort of thing with other AIs, but I never got code that worked. This morning, I wanted to teach it how to draw a scroll saw pattern that didn't work even after I uploaded samples.
