Like ChatGPT with side conversations branched from any point in your chat, except it picks the best AI for what you're doing and helps you make better decisions.

You run the two side by side, see which one actually holds up, and fold the good parts back into the main one.

Doesn't ChatGPT already do this? It forks. Edit a message and you have made a branch. But you cannot see it, you cannot compare it against the version you abandoned, and you certainly cannot combine them.

GPTree branches across models, so the same question runs through ChatGPT, Claude and Gemini on identical context. Every branch is a place on a tree you can walk back to. And you can merge them: take the reasoning from one, the numbers from another, and the structure from a third, into one answer with a record of where each part came from.

You don't have to start over. Import your ChatGPT history and every edit and regenerate you ever made becomes a real branch you can actually navigate. Hundreds of conversations arrive sorted into named projects, not a wall of titles. The months you spent teaching ChatGPT about your work come with you.

If one model in one thread is genuinely working for you, keep using it. GPTree is for the work where being one-shot right matters more than being fast.
