 ## What it does
 
 Every time you regenerate a response or edit a message in ChatGPT or Claude, the conversation splits into a new branch. These branches are invisible by default — Chat Branch Visualizer makes them a navigable tree.
 
-- **Branch tree** — renders every user and assistant turn as a node graph
-- **Build full tree** — auto-traverses all branches to build a complete map
-- **Navigate** — click any node to jump to that point in the conversation
-- **Fit / Zoom / Locate** — pan and zoom freely; jump to your current position
-- **Snapshot** — restores your last tree when you reopen a tab
-- **Standalone viewer** — pop the tree out into a full tab
