Chatbox - Powerful AI Client

This app is perfect for anyone looking to run local models on their phone. There is no mandatory extra subscription fee, and you can use any provider you prefer or purchase a premium subscription if you choose. I appreciate that payment isn't required, but the developers still find a way to monetize responsibly. What I love most is that they aren't locking away essential functionality behind a paywall; it’s refreshing to see an app that respects user freedom without sacrificing the core experience.

am encountering a persistent API Error 500 when using the Gemini 3 model on an existing chat tab that has extensive history. The full error is: {"error":{"message":"Request contains an invalid argument.","type":"500"}}. It seems like the app might be sending a malformed request when the context window is large or when handling specific history formats. This started happening suddenly. Please issue a fix, as I need to access this specific conversation.

It’s a pretty good app. Works fine but missing a few key issues which I removed two points for. 1st: It doesn’t handle <think> tags and this is a very common use case for LLMs today and it just displays them as raw text. It also uses the raw <think> tags as chat names when it tries to get a name which is quite annoying when all I use it for is reasoning models. 2nd: it doesn’t allow passing in key parameters which makes its use quite limited. For instance, it does not allow configuration of context length. If I am processing a longer document, it will not get any of the earlier tokens. Otherwise, this is quite a good free app! I had to build my own web-based chat to overcome these two hurdles and I don’t currently use regularly.
