The standard advice for important things is to back them up. We back up photos. We back up code. We back up our taxes. Almost nobody backs up their AI — and almost nobody realizes that the AI they've been talking to for two years has more honest data about them than their journal.
That's a problem for two reasons. The first is that every provider has already, at some point, quietly trimmed memory, swapped a model, or changed defaults in ways that erased part of what their users had built. The second is that the version of you each AI has learned is stuck in that AI. ChatGPT can't hand it to Claude. Gemini can't read your Plaud transcripts. The whole modern stack is non-portable by default, and every export you don't do today is a gap in a future model's understanding of you.
This guide is the unsentimental, tool-by-tool walkthrough. What to click. What's actually in the file. What's missing. And what to do with the export so it isn't just a JSON file rotting in your downloads folder.
