ChatXOS

Unified AI Model Access

ChatXOS brings together all the major AI models you need into one convenient app. This includes powerful tools like ChatGPT for writing and analysis, Claude for coding and complex tasks, Gemini for research, Grok for real-time information, and DeepSeek for reasoning. You no longer need to download separate apps or log into multiple websites; every leading AI is at your fingertips, ready to help with whatever you're working on.

Switch Models Mid-Conversation

One of the most powerful features of ChatXOS is the ability to switch between different AI models within the same conversation thread. If you're not satisfied with one AI's answer, or if a different model is better suited for the next part of your task, you can switch instantly with a single tap. This allows for dynamic, flexible conversations where you can leverage the unique strengths of each AI as you go.

One Unified Chat History

Forget about losing track of which conversation happened in which app. ChatXOS keeps every single interaction with every AI model in one centralized, searchable chat history. This makes it incredibly easy to find past ideas, reference old code snippets, or continue a brainstorming session, no matter which model you were using at the time. It brings ultimate organization to your AI workflow.

Side-by-Side Answer Comparison

Making an informed decision is easy with ChatXOS. You can quickly generate responses from multiple AI models to the same prompt and view them side-by-side. This allows you to compare their different approaches, tones, and information quality at a glance, helping you choose the best answer or synthesize the best parts from each one for your project.
