Think past the first answer.
A workspace for following the interesting parts of an AI conversation without losing the original thread.
A good question rarely moves in a straight line.
Most chat interfaces are designed to keep moving forward. But the useful part of a conversation often begins when one sentence makes you pause, question it, and take a different path.
Opening a new chat loses the moment that made the question matter. Staying in the same one turns the original line of thought into noise. I wanted both paths to remain visible.
A branch is not yet a thinking structure.
ChatGPT and Codex can open threads or branches. Thread Chat is built around what happens after the split: keeping the relationship between ideas intact as you keep exploring.
Start from the exact thought
Every branch inherits the conversation at the sentence you selected, so the question starts with the context that made it meaningful.
Keep the main line clear
A branch develops beside the original conversation. You can go deep without turning the main thread into a transcript of detours.
Return to the whole shape
Your tree and workspace persist across visits, and a useful branch can become a Markdown artifact without losing where it came from.
Keep the question. Follow the branch.
Give the next interesting thought somewhere to go without leaving the one that brought you here.
