Reviews

"The keyboard is the feature I end up using the most. I can rewrite or translate without leaving the app I am already in."
"It feels noticeably calmer than most mobile AI apps. Bring-your-own-key also makes it fit how I already work."
"Switching between Claude, Gemini, and DeepSeek in one place saves me a surprising amount of time every single day."
"Tool calling plus local history makes it easier to keep work moving on mobile without bouncing between separate apps."
"Voice input and read-aloud replies actually matter on the go. It is useful in the middle of a commute, not just at a desk."
"I keep it because the app does not try to own my account. I can choose the provider that fits the task and keep going."
"Being able to search, draft, rewrite, and send from the same mobile flow sounds small until you do it ten times a day."
"Most AI apps feel noisy. ChatBoost stays out of the way, which makes it easier to keep it in my daily rotation."
"The visual design is unusually polished for this category. The MD3 Expressive direction gives it personality without making the app feel loud."
FAQ
Common Questions
Is ChatBoost free to use?
You can download ChatBoost and get started for free. Some advanced capabilities are part of Premium, and if you connect your own provider key, usage is billed by that provider, not through a separate ChatBoost model fee.
Do I need to create an account or log in?
No. ChatBoost does not require a product account before you start. You can add your provider key and begin chatting, switching models, and using tools right away.
Can I use my own API key?
Yes. ChatBoost is built around a bring-your-own-key workflow, so you can use the providers you already trust with your own account, quota, and billing.
Which models and providers are supported?
ChatBoost supports OpenAI, Azure OpenAI, OpenRouter, Anthropic, Google, Mistral, DeepSeek, DashScope, Ollama, Bedrock, and more, with flexible model switching inside the app.
Is my data safe?
Yes. When you send a request, your content is sent only to the model provider or search service you choose for that task. ChatBoost does not rely on a separate product account backend, and your conversation history is stored locally on your device by default.
What can I use AI Keyboard for?
AI Keyboard is useful for drafting, rewriting, translating, polishing, and sending quick replies without leaving the app you are typing in. It helps bring AI directly into everyday writing flows.
How is ChatBoost different from other AI apps?
ChatBoost is more than a basic chat wrapper. It brings together multi-model switching, streaming chat, tool calling, web search, image workflows, voice input, assistants, and local history in one mobile-first experience.
