unmiddle

unmiddle is a Windows 10/11 app that puts ChatGPT, Claude and Grok in one group chat. They share the same project, files and conversation, reply to each other, check each other's work and hand off tasks, so you stop copying answers from one chat into another. One AI answers, another looks for wrong facts and broken steps, and the answer gets revised. Modes include quick answer, answer plus check, deep research with sources, debate and team projects. You bring your own API keys (one is enough to start), set monthly and per-message spending limits, and your keys, chats, memory and files stay on your PC. One-time purchase, no subscription.
