You got me excited that Github Copilot was free. Was going to post to tell you it is, in fact, not free.
I've been using Bing on Edge browser for a while now, it's super useful! Sad that they rebranded it to Copilot though, "I have been a good Bing :)" will be forever in my memory. [1] RIP Bing, you were a good chat mode.
