Branch AI
View live ↗What it is
Branch AI wraps the Claude Code CLI and captures extended thinking as a live, navigable tree. Every reasoning step becomes a node. You can fork at any point, inject new context mid-thought, and diff runs side by side.
The problem it solves: Claude's extended thinking is powerful but opaque. You get a wall of reasoning you can't interact with. Branch makes it a structure you can explore, share, and collaborate on.
Why it exists
AI teams burn hours on opaque model failures. Branch turns reasoning into something inspectable — not a black box you hope produced the right answer, but a tree you can walk through, branch from, and understand.
Current status
