How to do it
Follow the steps in this order: the first isolates the problem in thirty seconds, the others fix it.
- Open the tool in an incognito (or private) browsing window. This mode ignores cache and extensions: if the site loads there, the problem is in your browser, not in the AI. Go to step 2. If it doesn't load even in incognito, skip to step 4.
- Clear the browser's cache and cookies. Press the keys for clearing data (on Windows and Linux the combination opens the dedicated window, on Mac the equivalent), choose "everything" as the time range and confirm. A corrupted cache is the single most frequent cause of blank screens and endless loading.
- Disable extensions one at a time, starting with ad blockers, script blockers, privacy filters and VPNs. They're the usual suspects: they interfere with the page's code and block it. Re-enable them afterward to find out which one it was.
- Check the service's official status page (search for "status" followed by the tool's name). If it reports an outage or maintenance, there's nothing you can do on your end: wait ten to thirty minutes and try again. Reloading over and over doesn't help.
- If you're using the app on your phone, clear the app's cache from the system settings, or switch from Wi-Fi to mobile data (or vice versa): often it's the connection acting up.
Check: after each step, reload the page with a forced refresh (hold down the reload button or use the full-reload key combination). If it starts working again, you've found the cause.
A concrete example
Paolo opens the AI from work and gets a blank screen. First he opens it in incognito: it works. So the problem is his browser. He clears cache and cookies, reloads: blank again. Then he thinks about extensions: he has an aggressive corporate ad blocker. He disables it just for that site, reloads, and the chat appears. The office network had nothing to do with it: it was the extension blocking the page's code. Five minutes, no call to IT support.
When it does NOT work (and how to fix it)
If it doesn't load even in incognito and the status says all is fine
When incognito mode fails and the status page is green, suspicion shifts to the network. A corporate firewall, a VPN or a slow DNS can block the site. Try from another network (tethering your phone's data is the quickest test): if it works from there, it's your network filtering the tool.
If the login screen keeps spinning
A login loop (you log in and it sends you back to the sign-in screen) is almost always the site's cache or cookies. Clear them specifically for that domain, close the browser completely and reopen it. If it persists, try a different browser: this isolates whether the problem is that browser or the account.
If the phone app closes by itself on opening
An app that crashes at startup usually gets fixed by updating it from the store or uninstalling and reinstalling it. Your chat history won't be lost: it's tied to the account, not to the installed app. You sign back in with your credentials and find everything again.
A tip from someone who actually uses it
Before touching cache and extensions, spend ten seconds on the service's status page. Half the times that "the AI isn't working" it's a momentary outage on the provider's side, and anything you do on your computer is wasted time. Checking the status first tells you right away whether the problem is yours or theirs, and saves you from taking the browser apart for nothing.
Frequently asked questions
If I clear the cache, do I lose my conversations?
No. Cache and cookies are temporary browser data; chats are saved on your account, on the provider's servers. After clearing the cache you'll be asked to log in again, but once back in you'll find all your conversations intact.
Does reinstalling the app delete my chat history?
No, and it's the fear that stops many people from trying the most effective solution. The history is tied to the account, not to the phone: you uninstall, reinstall, sign back in with your credentials and the chats are there again. The only thing that gets reset is the local cache, which is exactly what you want to clean out.
