About ChatXOS

ChatXOS is the definitive all-in-one AI chat application for iPhone, designed to eliminate subscription chaos and app-switching fatigue. It solves a critical problem for modern AI users: the need to juggle multiple expensive subscriptions to access different models like ChatGPT, Claude, Gemini, and Grok. Instead of paying $90 or more per month for separate services, ChatXOS consolidates access to 18+ leading AI models from top providers into a single, native iOS app for a flat monthly fee. The core value proposition is simple: get the right tool for every task without the financial and mental overhead. Built with a mobile-first philosophy, it offers a seamless, ad-free experience where you can fluidly switch between models like GPT-5.2 for general knowledge, Claude 4.5 Opus for complex coding, Gemini 3.0 for research, Grok for real-time news, and DeepSeek for cutting-edge reasoning—all within one continuous conversation. It’s engineered for developers, writers, students, founders, and any power user who relies on AI daily and demands both versatility and efficiency from their tools.

Features of ChatXOS

Model Switching Mid-Conversation

This core feature allows you to change AI models seamlessly within an ongoing chat thread. If an answer from one model is unsatisfactory or you need a different strength for a follow-up question, you can instantly switch to another provider without losing context. This dynamic flexibility means you never have to guess which model to use at the start of a conversation, enabling a truly adaptive and efficient workflow directly from your iPhone.

Compare Mode

ChatXOS's Compare Mode lets you run up to four different AI models simultaneously on the same prompt. The app presents all responses side-by-side, allowing you to quickly evaluate, contrast, and select the best answer. This is invaluable for verifying information, comparing coding approaches, or seeing different creative angles, saving you the time and effort of manually copying prompts between different apps or browser tabs.

Unified Chat Organization

All your conversations across every AI model are stored in one centralized, searchable history. You can organize chats with custom titles and pin important threads for easy access. This eliminates the frustration of scattered conversations across multiple platforms, ensuring you never lose valuable context and can easily pick up where you left off, regardless of which model you were using.

File & Web Search Capabilities

ChatXOS supports image and file attachments for use with vision-capable models, allowing you to analyze documents, diagrams, or photos. Integrated web search capabilities empower models like Gemini or Grok to pull in real-time information, ensuring responses are grounded with the latest data. This turns the app into a comprehensive mobile assistant capable of handling a wide array of practical tasks.

Use Cases of ChatXOS

Developers Debugging and Explaining Code

A developer can use Claude Opus to debug a complex function, then instantly switch to ChatGPT to generate a clear, commented explanation of the same code for documentation or a team member. Compare Mode can be used to test different algorithmic solutions from multiple models simultaneously, ensuring the most efficient and correct code is selected.

Writers and Students Crafting and Fact-Checking Content

A writer can draft an article section using Claude for its creative flow, then switch to Gemini to perform in-depth research and fact-check the content against current web sources. A student can use GPT for brainstorming essay structures and then employ DeepSeek for advanced reasoning to strengthen their thesis arguments, all in one organized thread.

Founders Making Data-Driven Decisions

A startup founder can use Grok to get real-time market sentiment and news on a competitor, then prompt Claude to analyze the implications for their business strategy. They can use Compare Mode to get diverse perspectives on a critical business problem from GPT, Gemini, and Claude, leading to a more well-rounded and informed decision.

AI Power Users Optimizing Workflows

Users who regularly interact with multiple AIs can consolidate all their subscriptions into one affordable app. They can create a single thread for a project, using each model for its specialty—coding with Claude, creative writing with GPT, research with Gemini—without ever leaving the app, dramatically streamlining their daily AI-powered productivity.
