Long AI conversations are hard to navigate. You end up scrolling endlessly, trying to find something you asked ten messages ago. Scroll adds a sidebar that shows every turn in your conversation. Click any item to jump between prompts and responses. It works on Claude, ChatGPT, and Gemini. Toggle it with Cmd+. Use arrows and Enter to navigate if you prefer. Switch between seeing all messages or just your prompts. It's straightforward, free, and open source. Hope it helps!
