Fork AI is a powerful multi-AI chat platform and AI workspace. Seamlessly switch between ChatGPT, Claude, and Gemini without losing context. Branch conversations, organize chats, and start free—no credit card required.
A Multi-AI Chat Platform & AI Workspace — work with multiple models in one place without restarting conversations or losing context.
Drag and drop to branch off alternatives, compare responses side-by-side, and keep your main line of thought clean. Each branch is its own thread.
Instead of dumping your entire chat, share a precise slice: a branch, a set of messages, or an AI summary—with full control over what is visible.
Different models excel at different tasks. Switch GPT-4, Claude, or Gemini on any branch—compare responses on the same context with zero re-explaining.
Fork AI runs on an ad-supported model so powerful AI stays accessible to everyone—no credit card, no paywall. Start free and upgrade when you're ready.
