well since there's no way to upload files in the writing assistant... and in looking to see if there's a "trick" your Frequently asked questions link won't open, you have no support bot, your LLM in the writing assistant section (Claude) has no idea what features the platform has. you get 1 star.... only reason it's that high is it's required to post this review. your title is misleading, I could overlook that *IF the app was good and worked. but it doesn't.. I'll be cancelling pro membership

is this a scam app? Paid for lifetime but it is non functional and email 'reports ' just loops back unsent sent multiple reports. Still doesn't have all the chatbots available. I bought the app for all those chatbots. But they dont function. Just some do.

misleading title, immitating the more popular lmarena.ai and charge huge amount. the app name appears as 'arena ai' but in playstore listed as 'LM Arena...', it already puts me off.
