About Tool

ChatBoost is designed to provide a lightweight, flexible interface for accessing advanced AI chat capabilities on your mobile device. Instead of relying on a built-in model locked into the app, you supply your own API key and choose from different model providers, giving you more control over performance, cost and provider. The app solves the hassle of switching between different AI chat clients and having to log in repeatedly; it also tracks your API usage, stores chat history locally and supports extras like voice, images and prompt libraries. Whether you’re experimenting with language models, writing content or just chatting casually, ChatBoost brings a neat mobile solution.

Key Features

• Use your own API key for OpenAI, Azure OpenAI, Claude or Gemini models
• No login required—start chatting once the key is set up
• View API usage statistics and token consumption
• Local chat history storage on device
• Prompt library support and customizable prompts
• Stream responses, voice message support, image-vision mode (for supported models)
• Dark mode, Material design, lightweight UI for Android

Pros:

• High flexibility: supports multiple AI providers rather than being locked into one
• Privacy-friendly: you manage your own API key and data stays local
• Useful extras: prompt libraries, usage stats, voice/image support
• Good value for users already working with AI APIs who want a mobile client

Cons:

• You must supply your own API key there’s no “free unlimited model” built in
• Quality depends on the model you choose (so the app is a shell rather than full AI)
• Some setup/configuration needed for non-technical users (API keys, provider choice)
• Mobile UI may not match full desktop experiences for heavy-writing or editing

Who is Using?

ChatBoost is ideal for AI enthusiasts, developers, writers, students or hobbyists who already use AI models and want a flexible mobile chat client. It suits users comfortable managing API keys and who want access to multiple provider models from one app. It’s less suited to casual users who want zero setup or non-tech users who prefer plug-and-play.

Pricing

The app itself is freely downloadable from the Google Play Store. The cost depends on the model/API key you supply (e.g., OpenAI billing). Some in-app purchases may unlock additional features (voice, prompts, usage tracking). Since you're using your own API key, you pay your provider’s rates.

What Makes It Unique?

ChatBoost stands out by offering multi-model support + no login requirement and letting you control your API usage. Unlike many mobile AI chat apps that lock you into one model or provider or operate on their own servers, this app gives you flexibility and data control as long as you supply the backend.
