You don't have to retrain Claude from scratch. Here's the exact step-by-step to import everything ChatGPT knows about you into Claude — including the official prompt.
I've been using ChatGPT for close to three years. It knows how I write, what I work on, how I like my answers structured. That context took months to build up without me even realising I was building it.
When I started using Claude more seriously, that was the one thing annoying me. Not features. Not price. Just the idea of explaining myself all over again.
Claude actually has a solution for this. There's a memory import feature — you pull what ChatGPT knows about you and drop it into Claude. Here's how it works.
What you'll need
A ChatGPT account (free or paid works), a Claude account (free at claude.ai), and five minutes if you're slow about it.
Step 1 — Go to Claude's memory import page
claude.com/import-memory, or the long way: claude.ai → profile → Settings → Capabilities → Memory → Import.
Claude gives you a prompt. Don't just glance at it and move on — copy the whole thing, exactly as written.
Step 2 — Paste it into ChatGPT
New ChatGPT chat. Paste the prompt. Here's what it says, so you can do this right now without opening Claude first:
I'm moving to another service and need to export my data. List every memory you have stored about me, as well as any context you've learned about me from past conversations. Output everything in a single code block so I can easily copy it. Format each entry as: [date saved, if available] - memory content. Make sure to cover all of the following — preserve my words verbatim where possible: Instructions I've given you about how to respond (tone, format, style, 'always do X', 'never do Y'). Personal details I've shared (name, location, job, interests). Professional context (industry, role, tools, workflows). Projects or goals I've mentioned. Preferences I've expressed about how you should behave.
What comes back is usually more than you expected. Instructions you forgot you gave it. Projects from six months ago. Preferences you set once and never thought about again.
Step 3 — Import it into Claude
Back to Claude. Settings → Capabilities → Memory → Import. Paste what ChatGPT gave you. Click Add to Memory.
Five minutes, maybe less if you're not reading every line of ChatGPT's output first (I did, it was interesting).
Check that it worked
Open a new Claude chat — not the same one — and ask: "What do you know about me?" or "What kind of work do I do?"
If it answers correctly, you're set. If something's off or missing, you can add it manually in Settings → Capabilities → Memory. Took me under a minute to fill in two things that didn't carry over.
A couple of things to know
Claude's memory is built around work context. Personal stuff that's not connected to how you actually use it may not stick — Claude prioritises what helps you work, not everything you've ever mentioned.
Also — don't quit ChatGPT. I still use both. They're good at different things, and now Claude actually knows who it's talking to.
Five minutes of setup. Weeks of not having to re-explain yourself. Worth doing once.
