✨ chat.cx is an AI agent and an AI chat workspace in one panel: an agent that does tasks in your browser tabs, and every AI chat you use, side by side. AI browser agent & chat, custom & local models in sidebar & assistant panel. Switch chatbots, chat with any page, AI chat workspace. ━━━━━━━━━━━━━━━━━━ 🤖 AGENT MODE (BETA): AN AI THAT WORKS IN YOUR TABS Tell it what you need and it does the steps in your own browser, signed in as you: it opens sites, reads pages, clicks, types, fills in forms, and moves between tabs. ✋ You stay in charge: it shows a plan of the sites it will use and how, and starts only when you approve. Or let it act without asking. 🚦 Site rules: make a site ask before every action, or block it. 🔑 Runs on your own model, through any API you connect with your key. It can use web search and your MCP servers along the way. ━━━━━━━━━━━━━━━━━━ 🗂️ ALL YOUR CHATS IN ONE PLACE ChatGPT, Claude, Gemini, Grok, and 30+ more chatbots, side by side in your browser. 🕘 Chat history: the latest chats from the main chatbots, in one list with search and filters. Refresh pulls the newest from each chatbot's own list. 🔖 Bookmarks: save a chat from its tab, file it into folders, drag to reorder, and find it again by search. Bookmark all open tabs in one go. 🔲 Split view: a grid of chats, with panes you can resize. Compare answers side by side, or open the same chatbot twice. 📣 Broadcast: write once under the grid and send it to every chat on screen. ━━━━━━━━━━━━━━━━━━ 📄 ASK ABOUT THE PAGE YOU ARE ON 📝 Insert the page's readable text, or just your selection, into the open chat. 📸 Capture the visible page, or drag out an area, and attach the screenshot. Take several for one message. 🖱️ Right-click a selection and choose Ask AI: a fresh chat opens with the text ready to use. Or ask about the whole page. ⚡ Prompt library: one-tap prompts like Summarize and Explain, ready to send. Edit and reorder them, or create your own. ━━━━━━━━━━━━━━━━━━ 🧩 PART OF THE BROWSER 🪟 Six surfaces: side panel (sidebar), toolbar popup, full-page tab, new window, app window, or a floating window that stays on top of everything you do. The toolbar icon and keyboard shortcut open whichever you prefer. 📌 Tabs hold their place: chats stay loaded while you switch, and Restore Last Page reopens the exact chat you left. 🔔 Leave a chat while it writes: its tab shows a small bar that fills once the answer is in. 🎯 The launcher: a slim pill on the edge of any web page that unfolds into your open chats. Right-click it to move it to another edge, keep it open, or hide it on that site. ✍️ Write from the page: hover a chatbot in the launcher and a composer opens beside it. Add the page's text or your selection, screenshots, or a saved prompt, then send. The panel opens and your message goes out. 🎛️ Every tab under control: reload, back and forward, a zoom level each tab remembers, open in a normal tab or window. Hard Reload re-syncs a login. 🎨 Make it yours: pin favorites to Home, dock the tab strip to any edge, light or dark theme, a theme color that tints the chats to match, voice input in embedded chats. ━━━━━━━━━━━━━━━━━━ 🔑 BRING YOUR OWN MODELS Connect the major AI providers through their own APIs, or any OpenAI-compatible endpoint, in the cloud or on your own machine. Requests go straight from your browser, with no proxy in between. 🧠 On-device AI: built-in AI chat with the on-device models, once your browser has it enabled. No endpoint, no key, and it works offline. ⚙️ Full per-API setup: base URL, key, default model, system prompt, sampling and reasoning effort, custom headers, streaming, connection test. 💬 A real chat client: saved chats with search, rename, pins, and date grouping, branch or duplicate a chat, plus temporary chats that save nothing. 🌟 Rich answers: markdown, highlighted code, math, right-to-left text, a live view of the model's thinking, and image output. 🖼️ Artifacts: web pages, documents, code, tables, SVG images, and diagrams, shown beside the chat, with versions, what changed between them, and export. 🛠️ Message tools: edit and resend, regenerate, quote, response versions, file attachments, token counts. 🎙️ Voice: dictate and have replies read aloud, with your browser's voices or a speech service you connect with your key. 🌐 Built-in tools your models can call: web search and reading web pages with no key needed, image generation through your own endpoint, and date and time. 🔌 Connect MCP servers, signing in where they ask: your models can call their tools, and their prompts and resources are ready to insert. 🔐 Keys stay local: stored in your browser, sent only to the endpoint you configured. ━━━━━━━━━━━━━━━━━━ 🔒 PRIVATE BY DESIGN No account. No proxy servers. Nothing collected. Chats happen directly between your browser and the services you choose, and what the agent reads goes only to the model you connected, so there is nothing of yours for us to hold or leak. ━━━━━━━━━━━━━━━━━━ 💎 THE REAL SITES, NOT A WRAPPER chat.cx embeds the actual sites. Sign in once in a normal tab and the workspace opens them already signed in. ✅ Your accounts carry over: same site, same history, same models and plan ✅ The real interfaces: when a provider ships a feature, you have it the same day ✅ Nothing in between: no account, no proxy servers, no usage data Browse the full catalog at https://chat.cx ━━━━━━━━━━━━━━━━━━ chat.cx is an independent browser extension and is not affiliated with, endorsed by, or sponsored by any of the AI providers named in this listing or available in the extension.
