Ratings and reviews

I've been using this to chat with local LLMs on my network running on KoboldCpp. I bought premium so I can iterate on system prompts. It was working great. But after an update today, it can't seem to communicate with my KoboldCpp server anymore. It says CLEARTEXT communication is not supported by network security policy. What changed? My KoboldCpp server is not using HTTPs, it's just hosted on local network.

Couldn't get this consistently working, took long time to return text when using it. Found was easier, faster and more functional to use the openAI API Web playground instead.

Love this app and have the premium version. Would be amazing if you added a "playground" mode like on openai's website for when I want direct control over system prompts and context window. Just a suggestion! Edit: is it possible to export the custom prompts you make? I searched all over but couldn't fine where they are stored. I had my own phone fail and I'd like to export all my prompts incase that happens again. :)
