Do you have your ChatGPT export ready?

MigrateMyChats works with your full ChatGPT data export — a ZIP file from OpenAI containing your conversation history. You'll need it before you can start.

Before you begin

Have your ChatGPT export ZIP downloaded and ready on your computer
Open Claude in a separate browser window — you'll be copying information back and forth during this wizard
Open ChatGPT in another browser window — you will need to reference your settings and preferences
Set aside approximately 15 minutes to complete all six steps
💡 You can act on each step inline as you go, OR wait and get a full consolidated action punchlist at the end — your choice

Here's exactly how to request your ChatGPT export:

Log into ChatGPT and click your profile icon in the top-right corner.

Go to Settings → Data Controls → Export Data and click Export.

OpenAI will email you a download link. Click it and save the ZIP file to your computer.

Once the ZIP arrives, come back here and click "Yes, I have my export" above.

⏱ Plan ahead: OpenAI typically takes 24–48 hours to deliver the export link. You cannot begin the migration without it.

Import to Claude

Step 1 — Capture your Personal Context

This step captures everything ChatGPT knows about you — your custom instructions, personality settings, characteristics, and memories — so nothing gets left behind. All sections are optional.

📍 Custom Instructions

In ChatGPT: click your profile icon → Settings → Personalization → Custom Instructions
Copy the text from the Custom Instructions field and paste it below.
In Claude: paste this into Settings → General → Personal preferences

📍 Base Style, Tone & Characteristics

In ChatGPT: Settings → Personalization — select your current Base style and tone and Characteristics settings below. The tool will translate these into plain-text instructions you can paste into Claude's Personal Preferences.

📍 More About You

In ChatGPT: Settings → Personalization → More About You
This includes fields like your nickname, occupation, and any other personal context you've provided. Copy and paste it below.
In Claude: this will be included in your Settings → General → Personal preferences alongside your Custom Instructions.

📍 Memories

In ChatGPT: click your profile icon → Settings → Personalization → Manage Memories
You will see everything ChatGPT has saved about you. Copy the full list and paste it below.
In Claude: go to claude.ai → Settings → Memory — use this as a reference to seed Claude's memory with the same context about you.

All sections optional — skip if you haven't configured these settings.

Step 2 — Enter your ChatGPT Project names

Open ChatGPT and look at your left sidebar. Type your Project names below — one at a time or as a comma-separated list — then press Enter or click Add. Click "More" in ChatGPT if additional projects are hidden below the fold. A "Misc" bucket is always added automatically for unmatched chats.

Your projects will appear here...

Why enter these manually?

ChatGPT's export file does not include project names or assignments — it's a known limitation of their format. Entering your project names here lets the tool sort your chats into the right folders automatically.

Where to find Project Instructions in ChatGPT

Open ChatGPT → click on a Project in your left sidebar → click the "..." menu in the upper right corner → select ⚙ Project Instructions from the flyout → copy the full instructions text and paste it into the field for that project below.

Step 3 — Capture your Project Instructions

ChatGPT's export file does not include the custom instructions you wrote for each Project — these live only in ChatGPT's settings. For each project below, go to ChatGPT → select your Project → "..." (upper right corner) → ⚙ Project Instructions → copy the instructions text and paste it in. These will be written as a header block in each project's output files so you can paste them directly into Claude Projects.

NOTE: If you do not use Project Instructions, you may leave these fields blank, fill in only the ones you need, or choose "Skip this step" above.

No projects entered — go back to Step 2 to add projects, or skip this step.
