Question outline
ThreadMarks reads your visible ChatGPT thread and builds a side outline from your user questions.
Chrome extension beta
ThreadMarks
A compact question-based outline for long ChatGPT conversations. Move through a long thread by the questions you asked, without rereading everything from the top.
Beta ZIP is for Chrome Developer Mode. The public one-click install will use Chrome Web Store.
Fast jump
Click a marker or hover the rail to reveal titles, then jump back to the part you need.
Local by default
No sign-up needed. The outline is generated locally in your browser, and your conversations are not uploaded.
Try the beta build
Download the ZIP, unzip it, then load the folder from Chrome Extensions with Developer Mode enabled.
