How I Switched from ChatGPT to Claude Without Losing Data

Step-by-step guide to switch from ChatGPT to Claude without losing your data, memory, or context. Export, migrate, and import automatically with AI Migrator.

Mar 08, 2026

"I've been wanting to switch to Claude, but ChatGPT knows me too well to start over."

I’ve heard some version of this dozens of times lately.

And it kept coming up after the blind test articles Karo (Product with Attitude) and I ran comparing ChatGPT, Gemini, and Claude, where a few of you left comments asking for help switching.

Substack comments from readers asking for a step-by-step guide to switch from ChatGPT to Claude, with one noting that ChatGPT has so much context on them that even lousy prompts yield decent results.

So I started looking into what’s available to help with this, and the answer is: not much.

Every guide out there says the same thing. Go to your settings, export your saved memories, and paste them into the new model.

But when I went to my own ChatGPT memory and scrolled through it, I realized I’d maybe keep 20 to 30% of what was there. Most of it was outdated. Some of it was just irrelevant. And the stuff that was accurate felt thin.

If I dropped that into Claude and expected it to know how I work, how I write, what I'm building, it wouldn't even come close. This was not going to be enough to migrate years of context I'd built with an AI that ended up knowing me better than most tools I use.

So I built something to fix it.

It’s called AI Migrator, and it does exactly what the name says: it takes your ChatGPT conversations, memories, and preferences, and turns them into a profile you can drop into Claude, Gemini, or any other AI.
Your new model knows you from the first message. No copy-pasting for hours. No manually rewriting your context. No starting over.

Upgrade to Paid

Here’s what we’ll cover today:

Let’s begin.

But first… why is everyone suddenly leaving ChatGPT?

People have been frustrated with OpenAI for a while. Models that felt worse after updates. Ads coming to ChatGPT. The for-profit pivot. Political donations from leadership. Then last week came the Pentagon deal, and that's when it all spilled over.

Here’s what happened: Anthropic (the company behind Claude) refused to let the Pentagon use its AI for mass surveillance and fully autonomous weapons. The Trump administration pushed back, labeled Anthropic a supply-chain risk, and ordered all government agencies to stop using Claude. Hours later, OpenAI signed its own deal with the Department of War.

That's when the #QuitGPT movement started. Reddit posts calling to cancel ChatGPT hit tens of thousands of upvotes. ChatGPT uninstalls spiked 295% in a single day.

And Claude became the number one app in App Store for the first time.

According to Anthropic, free users have grown by over 60% since January. Daily signups have quadrupled. Paid subscriptions have more than doubled this year.

So a lot of people are making the move right now.

But whether your reason for switching is political, practical, or both, the biggest blocker is the same: all that context you’ve built inside ChatGPT.

The problem: how do you move years of ChatGPT context to a new AI model?

Reddit post titled "Your AI knows you better than your friends, good luck breaking up" describing how switching from ChatGPT feels like starting over in a relationship where the other person has zero memory of you.

Right now, we have a few options:

Export your saved memories. But like I found with my own, most of them are outdated or irrelevant. And even the ones that are still accurate are just a fraction of what your AI has learned about you.
Use Claude's built-in import tool. Claude now has a memory import feature that gives you a prompt to paste into ChatGPT. ChatGPT then summarizes what it knows about you, and you drop that into Claude. It works, but the result is thin. A surface-level summary compared to everything you've built over months or years of conversations.
Export your full conversation history. ChatGPT lets you download all your data (I’ll show you how in a bit), but you can’t just drop that export into another model. It’s too full of one-off conversations and details you’d never want to carry over. And it wouldn’t fit into any model’s context window anyway. We’re talking hundreds of megabytes, sometimes gigabytes, of data.
Copy things manually. You could go through your old chats one by one and pull out the useful parts. But if you’ve been using ChatGPT for a year or more, that’s hundreds or thousands of conversations. Nobody has time for that.

In other words, unless you’re okay with starting more or less from scratch, the options available right now don’t give your new AI model enough context to work the way your old one did. That’s how I ended up building the AI Migrator.

How the AI Migrator automates your ChatGPT to Claude migration

How it works

You upload everything you have from ChatGPT: your exported conversations, saved memories, custom instructions. The AI Migrator reads through all of it and distills it into a compact, portable profile.

You can review, edit, and delete anything before exporting. You only move what’s relevant.

What data gets transferred from ChatGPT

Identity: who you are, your name, role, how you present yourself
Background and skills: your expertise, skills, and tools you use
Personal facts: hobbies, lifestyle, family, wellness
Goals and aspirations: what you’re working toward in career, business, personal life
Communication preferences: language style, response structure and format, tone, verbosity, how you prefer AI to talk with you
Projects: what you’re building, active and past
Patterns and habits: how you work, how you make decisions, your learning style

Works for Claude, Gemini, and any AI model

ChatGPT to Claude. Claude to Gemini. Gemini to ChatGPT. Any model to any model.

You don’t even have to leave ChatGPT to use it. If you’ve built a lot of context in one model and want the others to have it too, the AI Migrator lets you sync that context across all of them.

Your data stays private

Your uploaded files are processed on our servers and deleted immediately after extraction. We never read your conversations ourselves — AI handles the analysis.

The only thing stored is the extracted facts (like “prefers concise responses” or “works on a newsletter”), which are saved to your account so you can review and edit them. You can delete your facts and your account at any time from your dashboard.

Now let me walk you through the full process: how to export your data from ChatGPT, how to run it through the AI Migrator, and how to import your profile into Claude or any other model.

Step 1: How to export your data

In this video, I walk you through how to export both your memories and your data from all three platforms.

Exporting your data from ChatGPT

1) Your conversation history

There are two ways to export it:

Option 1: From your settings. Open chat.openai.com → Go to Settings → Data Controls → Export Data and confirm. OpenAI will send you an email with a download link. This usually takes 30 minutes to an hour, sometimes longer for heavy accounts.

Download the ZIP file, unzip it, and find conversations.json. That’s the file you’ll upload to the AI Migrator. The download link expires after 24 hours, so grab it as soon as you get the email.

Option 2: From the Privacy Portal. Go to privacy.openai.com → click "Make a Privacy Request" → select "I have a consumer ChatGPT account" → choose "Download my data" → log in → select your region → click "Submit Request".

You'll receive an email with your data. The export comes as a ZIP inside a ZIP, and the full archive includes everything: images, videos, billing information, and other data you don't need. What you care about is your conversations. So find the conversations-*.json files, and upload just those to the AI Migrator.

From my experience: I tried Option 1 several times over a couple of days and never got the email. Option 2 worked on the first try and I received everything.

2) Your saved memories

Open ChatGPT in the browser, not the app (in the app you can only copy them one by one) → Go to Settings → Personalization → Memory → Manage. Copy them all and paste them into the AI Migrator’s text field.

The tool combines both your memories and your conversation history into one profile, which gives you a much richer result than either one alone.

Exporting your data from Claude

Open Claude → Settings → Privacy → Export Data. You'll get an email with a ZIP file containing your conversations, memory, and projects. (If the full export doesn’t arrive, try exporting just the past 3 months instead.)

Exporting your data from Gemini

Gemini is more limited. Google Takeout gives you mostly metadata, and the Activity page only shows the beginning of each conversation. It’s what’s available for now.

If someone you know is thinking about leaving ChatGPT, send them this.

Step 2: How to migrate your ChatGPT data automatically

Once you have your exported data, head to ai-migrator.aiblewmymind.com/migrate.

Upload your conversations.json file (or multiple files)
Paste your saved memories, custom instructions (or any other context you want to include)
The migrator processes everything locally in your browser and extracts your profile
Review what it found and curate it: you can edit anything that's outdated (like marking a current project as past) and delete anything you don’t want to transfer
Download your full profile as Markdown, plain text, or JSON

The processing takes a few minutes. The reviewing and editing is up to you, depending on how thorough you want to be.

But by the end you have a complete profile that's ready to import into any AI model, so you're not starting from scratch.

Step 3: How to import your profile into Claude

Now that you have your full profile, here’s how to bring it into Claude.

Option A: Add to Claude’s memory (recommended)

This is the simplest path and works on all plans, including free.

Download your profile from the AI Migrator
Open a new chat at claude.ai
Drop the file into the chat (or paste the contents) and send this prompt:

“This is my personal profile and preferences exported from another AI assistant. Please store all of this information in your memory so you can reference it in future conversations.”

Make sure Claude’s memory is enabled first: Settings → Capabilities → Memory. That’s it. Claude now knows who you are, how you work, and what you’re building.

Once your profile is imported, you’re ready to go. If you want to get the most out of Claude from here, my complete guide walks you through everything inside it so you can use it like the top 10% of users.
If you’re considering Gemini as well, I wrote a full guide to every feature inside it.

Option B: Add project context to Claude Projects

The AI Migrator includes your projects in your profile, but you can download them separately. If you want to continue a project you started in one AI inside another, download it and add it to Claude Projects → Create Project → Project Knowledge.

Full import guide with all the details: import to Claude.

Not ready to leave ChatGPT? Use it for context sharing instead

The AI Migrator works for switching models, but it works just as well for sharing context across all of them.

The blind test proved that more often than not, different models are better at different things. Maybe you use ChatGPT for research but Claude for writing. Maybe you’re testing Gemini for tasks inside the Google ecosystem. The problem is that each model only knows what you’ve told it. They don’t share context.

With the AI Migrator, you export your context from whichever model you’ve used the most and import it into all the others. "Even if you're not canceling any subscription, all your AI models can know you.

Make Claude (and ChatGPT) smarter with the AI Blew My Mind MCP

Once you’re set up in Claude, or even if you’re keeping ChatGPT in parallel, there’s one more thing worth connecting.

The AI Blew My Mind MCP gives you access to all my prompts, workflows, and image generation right inside your chat. It works in both Claude and ChatGPT.

But the part I love most is that you can save your own prompts in it too. Instead of keeping them scattered across notes, docs, and screenshots, you just tell Claude or ChatGPT to save a prompt.

Next time you need it, you ask for it in the chat. No more digging through files wondering where you stored that one prompt that worked so well.

Takes one minute to set up. Here’s how.

Your context belongs to you

Whether you're part of the #QuitGPT wave switching to Claude right now or you just want all your AI models to share the same context about you, the point is the same: your context shouldn't be locked inside any platform. You built it. It's yours. Take it wherever you want.

Start your migration.

Are you switching to Claude, staying with ChatGPT, or using both? And what’s been the biggest blocker for you when it comes to switching? Tell me in the comments.
