AI Chat Sidebar & Assistant Workspace, All-in-One Side Panel | chat.cx

🔖 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 any endpoint that speaks the OpenAI-compatible Chat Completions API, in the cloud or on your own machine, and talk to it straight from the browser. 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, custom headers, streaming, connection test.

💬 A real chat client: persistent threads with search, rename, and date grouping, plus a temporary mode that saves nothing.

🌟 Rich answers: markdown, highlighted code, math, right-to-left text, a live reasoning view, and inline image output.

🛠️ Message tools: edit and resend, regenerate, quote, response versions, voice in and out, file attachments, token counts.

🌐 Built-in tools your models can call: web search and web fetch with no key needed, image generation through your own endpoint, and datetime.

🔌 Connect MCP servers: 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, so there is nothing of yours for us to hold or leak.
