I Built a 'Time Machine' for AI Coding Sessions — Here's Why

Last Tuesday, I spent two hours in a Claude Code session refactoring an authentication module. Somewhere around the 45-minute mark, the AI suggested an elegant approach to token rotation that I had never considered. It was one of those moments where you think, "I need to remember this." I did not remember it. By the time I went looking, the terminal had scrolled past it. The conversation was a wall of text with no structure. The reasoning behind the change, the back-and-forth that shaped it, the intermediate states of the code -- all gone. Dissolved into the void of my scrollback buffer. If this sounds familiar, keep reading. The Problem Nobody Talks About AI coding assistants have changed how I work. Claude Code for backend logic, Cursor for frontend iteration, Gemini CLI for quick prototyping. The productivity gains are real and significant. But there is a glaring hole in the workflow that nobody seems to address: AI coding sessions are completely ephemeral. Think about it. Every oth
