chat.cx
chat.cx is a browser extension (Chrome/Chromium-based browsers) that embeds the actual web chat interfaces of many AI providers into a persistent side panel, popup, or full-page tab so you can keep conversations one click away without creating a new account or routing traffic through third-party servers. It supports both provider-hosted sites (ChatGPT, Claude, Gemini, Grok, Perplexity, and more) and native API endpoints compatible with the OpenAI Chat Completions API, including local endpoints such as Ollama or LM Studio.
The product is aimed at users who want to streamline multi-model workflows in the browser: compare responses side-by-side, keep chats loaded while browsing, send page text or screenshots into chats, and run API-backed native chats using keys stored locally on the device.
All your AI chatbots in one panel while you browse. ChatGPT, Claude & more. chat.cx is a AI Tool featured on Dang.ai. Learn more about chat.cx's AI tool.

Embedded real provider sites
Embeds the real chat sites (chatgpt.com, claude.ai, gemini.google.com, and nearly 30 others) inside a browser panel so your own accounts, history, and subscriptions carry over.
Bring Your Own Keys (BYOK) / Native API chats
Point the extension at any OpenAI-compatible endpoint (OpenAI, OpenRouter, Groq, Azure, xAI, local Ollama/LM Studio) and configure base URL, key, model, system prompt, sampling, headers, and streaming with a connection test.
Multi-tab persistent workspace
Chats open as tabs inside the extension that keep state, stay loaded in the background, and restore the exact conversation when reopened. You can open the same service multiple times.
Multiple surfaces
Use the side panel, toolbar popup, full-page tab, new window, or a standalone app window; launcher toolbar and Alt+S shortcut follow your chosen surface.
Page context insertion
Send page text, a selection, or a screenshot into any chat from the panel or via right-click Ask AI; captured context is preserved even if a site cannot accept automatic inserts.
Chat client features
Threads with search and temporary mode, markdown with highlighted code and math, live reasoning view, voice in/out, attachments, and per-message timing and token stats.
Local-first keys and privacy
No chat.cx servers or relay — traffic goes directly from your browser to each provider; API keys and native-chat history are stored in the extension's local storage and are never synced to any cloud.
Searchable catalog and customization
Catalog of ~30 chatbots with a new-tab picker, pin favorites to Home, reorder tabs, dock/collapse the tab strip, and light/dark/system themes.
Tools
Keyless web search parsed locally, web fetch, and image generation behind a cost confirmation; a single set of switches applies across chats.
Hard reload and session management
Hard Reload re-syncs a login into the panel when a site shows you signed out there but remains signed in in a normal tab.
Pricing
Full product with a limit of up to 5 chat tabs; no account, no trial, no card required.
