QuadCode

QuadCode is a desktop app that splits your screen into 4 parallel AI terminal sessions. Run Claude in one pane, Gemini in another, Codex and your machine terminal in the others — all at the same time. Type once in broadcast mode, all 4 answer. Or run them independently on different tasks. Stop switching tabs. Stop losing context. Just run them all and pick what works. Built for developers who use AI heavily and are tired of the tab shuffle.
