We run everything through a single optimized architecture instead of paying for each consumer plan. That lets us offer all five models for a fraction of the usual ~$90/mo you'd spend on ChatGPT Plus, Claude Pro, Gemini Advanced, Grok Premium, and DeepSeek.

ChatXOS supports ChatGPT by OpenAI, Claude by Anthropic, Gemini by Google, Grok by xAI, and DeepSeek. We're adding more models based on user demand.

We're launching on iOS first. Android support is planned for the future.
