You chat with free built-in CX AI or your own OpenAI, Claude, Gemini or OpenRouter key, and CX can browse, search the web, run tools, watch pages for you and work offline with on-device models. - **Is CX Agent free?** Yes. CX Agent is free to download and use. The built-in CX AI (Auto, Smart and Fast) is free with fair-use limits that refill automatically, and offline models cost nothing. If you add your own OpenAI, Claude or Gemini key, that provider bills you directly. The free app shows small in-app house ads. - **How do I download and install CX Agent?** Open cxagent.pages.dev/download on your Android phone and tap Download to get the official APK (version 2.3.37, about 54 MB, Android 8.0 or newer). Open the file, allow “Install unknown apps” for your browser or file manager when Android asks, then tap Install. CX Agent is distributed as a direct APK, so download it only from the official site. - **Is CX Agent safe to install?** Official builds come only from cxagent.pages.dev and use the package name com.cx.agent. Android permissions such as location, microphone or notifications are requested only when you use a feature that needs them, and tools ask for your approval before changing things unless you allow otherwise. Your own API keys stay on your device, and cloud backup is opt-in. - **Which AI models does CX Agent use?** CX Agent includes free CX AI with Auto, Smart and Fast modes that pick a model for you and switch to a backup model if one is busy. You can also add your own key for OpenAI, Anthropic Claude, Google Gemini, OpenRouter, Groq or any OpenAI-compatible API, or download offline models (CX Lite, Balanced, Smart) that run on your phone. - **Who made CX Agent?** CX Agent is made by ChandailX, a company from Jammu and Kashmir, India. Founder Mehran Chandail created the app, and K Nithin is co-founder of CX Agent and founder of Fubrio (fubrio.in), the supporting company of CX Agent. The app launched publicly in October 2026. Contact: chandailxcompany@gmail.com. - **Does CX Agent work offline?** Yes. Download an offline model once in Settings → Providers → Offline models (CX Lite needs about 350 MB), then chat with no internet connection. Offline chats never leave your phone. Free CX AI, web search, integrations and other online tools still need a connection, so CX tells you when a task needs the internet. - **How is CX Agent different from the ChatGPT app?** The ChatGPT app is built around OpenAI’s own models. CX Agent is a multi-model agent: use free CX AI, your own OpenAI, Claude, Gemini or OpenRouter key, or offline models. On Android it also has a built-in AI browser, a Linux workspace, monitors, scheduled tasks, a Telegram bot and phone tools that ask before acting. ## Documentation ### Getting started - [Welcome to CX Agent](https://cxagent.pages.dev/docs/welcome/): What CX Agent is, what it can do on your phone, and how these docs are organised. -
