Multi-AI Chat

Run reliable multi-AI workflows across ChatGPT, Claude, Gemini, and Grok from one side panel.

Multi-AI Chat brings ChatGPT, Claude, Gemini, and Grok together in one Chrome Side Panel. Ask once, compare multiple perspectives, or run structured multi-AI workflows using the provider tabs you are already signed into. No model API keys and no separate Multi-AI Chat backend are required. WORKFLOWS • Free — Send one prompt to multiple AI providers in parallel and compare their answers. • Debate — Pro → Con → Judge → Synthesis. • Consult — Two independent answers → Review → Final answer. • Coding — A structured multi-step workflow for planning, implementation, testing, review, and acceptance. • Roundtable — Multiple rounds of discussion designed to progressively converge on an answer. BUILT FOR RELIABLE MULTI-AI WORK Multi-AI Chat tracks each request independently so late responses do not interfere with the wrong workflow. Provider readiness is verified before a run, active workflows can be stopped, and Roundtable failures can be handled with Retry, Skip, or Cancel. FEATURES • Works with your existing signed-in ChatGPT, Claude, Gemini, and Grok tabs. • No model API keys required. • Up to 30 conversations stored locally in Chrome. • Continue with follow-up questions after a workflow completes. • Safe Markdown rendering. • Light, dark, and system appearance. • English, Traditional Chinese, Japanese, German, and Korean interface languages. • Optional publishing to HackMD using your own token. PRIVACY There is no Multi-AI Chat server, analytics, advertising, tracking, or telemetry. Prompts are sent directly to the provider pages you choose. Settings, conversations, and the optional HackMD token are stored locally in your browser. Content is sent to HackMD only when you explicitly choose to publish it. Multi-AI Chat is open source. IMPORTANT Multi-AI Chat automates third-party web interfaces. Changes to provider websites may temporarily affect compatibility, and automated use may be subject to each provider's terms. Use only accounts and content you are authorized to use.
