Simple Chat Hub is a workspace built around one simple idea: instead of opening half a dozen AI sites in separate tabs, put them side by side and ask everyone at once. The extension and desktop client each place the real website of ChatGPT, Gemini, DeepSeek, Doubao, Claude, Qwen, Perplexity and other platforms into their own column within a single window.
A shared input at the bottom accepts your question once and delivers it to every platform in the current space. Answers arrive side by side, and because each column maintains its own conversation context, you can follow up in whichever answer was most useful. Files can be added by selecting, pasting or dragging them in. "Spaces" let you save a platform combination for a recurring task — a research setup, a coding setup, a study setup — with its own name, icon and keyboard shortcut.
Practical extras round out the workflow: a prompt library with one-click insertion and prompt optimization, long-screenshot export of a whole conversation, saved conversation links that reopen the right platform pages and layout, and a launch-link feature that lets Alfred or another launcher open the Hub with a question ready to send. The project is actively maintained — the Chrome extension is at version 2.8.0 with a 4.9 rating from 87 reviewers and about 6,000 users, and the companion desktop app ships for macOS, Windows and Linux from GitHub.
