ChatGPT → Claude Migration | Transfer Your Memory in 60 Seconds

What Can Be Transferred in a ChatGPT → Claude Migration

What gets transferred is the information accumulated in ChatGPT's "Memory" feature. This includes things ChatGPT automatically remembered from your conversations — your profession, preferred writing style, frequently used tools, background context you've shared repeatedly, and so on.

What can be transferred

• Memory items shown in your ChatGPT memory list
• Personal context such as name, job title, and areas of expertise
• Instruction preferences like "please answer in bullet points" or "please respond in English"

What cannot be transferred

• Past conversation history (chat logs)
• Custom GPTs configurations
• Files and images created in ChatGPT

Only explicitly registered memory items are transferred. Keep in mind that this is not a feature for migrating your entire conversation history.

Why Switch to Claude Now

Anthropic released Claude Opus 4.7 in April 2026, delivering significant improvements in coding, long-text processing, and vision analysis. Claude's free plan now also supports the memory feature, making it easy to try the switch without any migration cost (source: Impress Watch — "Claude now supports memory migration from ChatGPT and others").

The most commonly cited reasons for switching are:

• Handling long and complex tasks: context window of up to one million tokens
• High safety standards: design philosophy based on Constitutional AI
• Projects feature: separate management of system prompts and memories by use case
• Claude Code integration: terminal-integrated tooling for developers

Prerequisites: Reviewing Your ChatGPT Memories

Before starting the migration, take a moment to review what's stored in ChatGPT's memory.

1. Log in to ChatGPT and click your account icon in the lower left
2. Go to Settings → Personalization → Manage Memory
3. A list of currently stored memory items will appear

If there are only a few items, it may be faster to manually add them to Claude's memory after switching.

Claude Settings: Turning On the Memory Feature

Claude's memory feature may not be enabled by default. Check this before importing.

1. Log in to claude.ai (free plan is fine)
2. Click the icon in the lower left → open "Settings"
3. Select the "Capabilities" tab
4. Check the "Memory" section and confirm the toggle is ON

Once memory is enabled, a "start import" button will appear.

How to Export Your ChatGPT Memories

The migration flow provided by Anthropic is as follows (source: ITmedia — "Anthropic begins offering a tool to make migrating from ChatGPT to Claude easier"):

1. In Claude, go to Settings → Capabilities → Memory → click "start import"
2. A popup will display an "export prompt"
3. Copy that prompt
4. Open a new chat in ChatGPT and paste the copied prompt, then send
5. ChatGPT will output your memory information in a code block format
6. Copy all of the output text

The prompt is a dedicated format designed by Anthropic that instructs ChatGPT to output its stored memories as structured text.

How to Import into Claude

With the copied text from step 6, return to Claude.

1. Go back to the "start import" popup in Claude (or reopen it via Settings → Memory)
2. Paste the code block content obtained from ChatGPT into the text input field
3. Click "Add to memory"
4. When you see the "Memory updated" confirmation message, you're done

The entire process takes about 60 seconds (source: Qiita — "Complete ChatGPT Memory Migration to Claude in 60 Seconds").

Reviewing and Adjusting After Import

It is recommended to open Claude's memory list immediately after import to check the contents.

• Settings → Memory → "Manage memories"
• Individual items can be deleted as needed
• Missing information can be added manually via "Add memory"

Because ChatGPT and Claude organize memories differently, some items may be registered in an unexpected format. Having a brief conversation with Claude right after migration to verify that context is reflected correctly will give you peace of mind.

Organizing Memories Further with Projects

Claude's "Projects" feature lets you manage memories and system prompts separately by use case.

• Work project: register your job type, responsibilities, and frequently used tools
• Study project: register the language you're learning, materials, and progress
• Personal project: register hobbies and lifestyle preferences

While ChatGPT manages all memories in one place, Claude lets you separate them by purpose for more accurate responses. Making use of Projects after switching enables a level of personalization that goes beyond what ChatGPT offers.

Frequently Asked Questions After Switching

Q: Can I migrate memories on the free plan?
A: Yes. The memory feature is available on Claude's free plan, so you can migrate without any additional cost.

Q: Can I view my ChatGPT conversation history in Claude?
A: With the current feature set, migrating conversation logs is not possible. Only memory (remembered) items are transferred.

Q: Can I continue using ChatGPT alongside Claude after switching?
A: Absolutely. Claude and ChatGPT are independent services. You can keep accounts with both and use each depending on your needs.

Q: How do I delete migrated memories later?
A: Go to Settings → Memory → "Manage memories" and use the delete button next to each item for individual deletion. "Clear all memories" is also available for bulk deletion.

Switching from ChatGPT to Claude is a process that can be completed in just a few minutes using the official memory import feature. Now that the long-standing barrier of "losing accumulated context" has been removed, the threshold for giving Claude a serious try is almost nonexistent. We recommend starting with the free plan to migrate your memories and see how it feels.
