Why chat.cx exists
Using AI meant a tab for every chatbot and another app for every API key: copy from the page, switch, paste, wait, and switch back. The answer you needed got buried behind whatever you opened next.
chat.cx brings it all into one panel beside the page you’re reading. The AI sites you already use open as they are, with your own accounts. Next to them sits a full chat app for any model you choose: your own API keys, a model running on your computer, or Chrome’s built-in AI. Both work the same way, in split view, in a quick chat on any page, and with the page you’re on.
It’s designed around real daily tasks: asking about the page you’re reading, comparing answers from several AIs, keeping a long answer beside your work, trying a new model with your own key, and finding an old chat again.
We keep chat.cx focused and fast. Every feature has to save you a click, a copy-paste, or a trip to another tab.
See every featurechat.cx is independent and not affiliated with any AI company. It doesn’t sell AI access: the sites work through your own accounts, and the chat app through your own keys.
What we care about
chat.cx is built around one idea: AI should help you work without pulling you away from it.
Less tab switching
Every AI chat sits beside your work, one click away, instead of in another tab.
Context on demand
Send the page, your selection, or a screenshot to any chat when you ask.
Stay in your flow
Ask right on the page with a quick chat, and keep reading while the answer comes.
Every answer side by side
Ask several AIs at once and compare, instead of copying between tabs.
The right AI for each task
Switch between the AI sites you use and your own models in one click.
Simple controls
Useful defaults and clear actions. Turn off anything you don’t need.
