About chat.cx

chat.cx is a Chrome extension for people who switch between several AI chat services during the day. Instead of opening a separate browser tab for each assistant, it loads them inside a side panel next to the current page, keeping each conversation running in its own tab. Its catalog covers dozens of services such as ChatGPT, Claude, Gemini, DeepSeek, Grok, Perplexity and Le Chat. Users can select text or send a screenshot of a page into a chat, ask several chatbots the same question in split view, and open a small launcher directly on a page. The free plan allows up to three chat tabs and five bookmarks, and a one time Early Supporter payment unlocks the rest.
