My experience: 1. I didn't have a working installation window after opening it for the first time. Maybe what fixed it was downloading and opening some random javascript repo, but maybe it was rather switching to "Trusted mode" (which makes me a bit nervous but ok).
2. Once the assistant window input became active, I wrote something short like "hi", but nothing happenned after pressing ctrl-Enter. I rageclicked around a bit, it's possible I have queued multiple requests. About 30 seconds later, suddenly I got a reply (something like "hi what do you want me to do"). That's .. not great latency. :)
3. Since I got it working, I opened the sidecar project and sent my second assistant prompt. I got back this response after few tens of seconds: "You have used up your 5 free requests. Please log in for unlimited requests." (Idk what these 5 requests were...)
I gave it one more go by creating an account. However after logging in through the browser popup, "Signing in to CodeStory..." spins for a long time, then disappears but AIDE still isn't logged in. (Even after trying again after a restart.)
One more thought is maybe you got DDos'd by HN?
