I stopped trusting Claude and ChatGPT’s memory and setup my own memory system

Unless you export your preferences, a new AI tool starts from zero. And even when you do, it rarely behaves like the old one. Maybe it mixes up the context for different projects, or remembers an old preference that you no longer use. You can tackle this by modifying what the new chatbot remembers, asking it to forget old preferences, and reminding it of what context fits in with what project.
