About chat.cx

chat.cx, short for Chrome eXtension, is a browser add-on that opens many AI chat services in a single side panel. Instead of keeping separate tabs for each assistant, a user can switch chatbots from the panel, use custom and local models, and chat about whatever page is currently open.

The supported list on the site is long and includes ChatGPT, Claude, Gemini, Copilot, DeepSeek, Grok, Perplexity, Poe, Meta AI, Le Chat and OpenRouter Chat, among others. The workspace can be customized, and the vendor offers pages for features, pricing, an FAQ and an about section. It runs as a Chrome extension, with the Chrome Web Store install as the entry point.
