Learn about AI memory
Plain answers to the questions people ask about AI apps that remember: how Claude, ChatGPT, Claude Code and Cursor keep what they know about you, and how to keep one memory across all of them. Written by Zaaheen and checked against each company's own help pages.
- How to share memory between ChatGPT and Claude
They can't read each other's memory. Copy it across, use Claude's import, or give both apps one shared memory.
- Does Claude Code remember between sessions?
Yes, within one project on one computer. What CLAUDE.md and auto memory keep, what loads each session, and what they leave behind.
- How to keep one memory across Claude Code, Cursor and Codex
Each keeps its own memory. Share project rules through one AGENTS.md, and what they know about you through one shared memory.
- Do you need an AI memory tool, or is a notes file enough?
Often enough for one project in one tool. Where a file falls short, and why you'll likely want both.
- How to switch from ChatGPT to Claude without starting over
Bring your ChatGPT memory, instructions and old chats to Claude, how long each step takes, and how to never move them again.
