Need ideas! around Chat GPT mobile experience

I am working on developing one Android application called ChatLikePro using the Chat GPT API. currently my app has following features - text chat - regenerate response - edit response/queries - locally store chat history - search You can find it on the Play Store. https://play.google.com/store/apps/details?id=com.chatlikepro I used qonversion for managing subscriptions. I don't know if people would be interested in paying for the above mention features. I should have validated my idea before developing this app but that's fine because I learnt lot of things in the process. can you guys let me know what features you look for in this app. And will you be interested in paying recurring monthly or just one time payment. waiting for your ideas and suggestions!
