How to transfer chat from ChatGPT to Claude, step by step

By the AgentMsgr team · Updated November 13, 2026 · 7 min read

Want to transfer chat from ChatGPT to Claude? There's no button that moves your chats over. As of November 2026, Anthropic's help center says Claude can't import conversation history from another AI. What you can move is the useful part: a single chat as text or a summary, your memory through Claude's own import tool, and your custom instructions and project files by copying and re-uploading them.

How to transfer chat from ChatGPT to Claude: pick your method

The right method depends on what you're bringing. Find your row:

Before you move everything, it helps to know how Claude's allowance works, since a long pasted chat uses more of it. Our Claude usage limits guide explains the five-hour and weekly limits.

Move one ChatGPT chat to Claude with a handoff summary

For a chat you want to keep working on, a summary usually beats pasting the whole thing. A long pasted thread is hard to read, and every later reply in Claude has to take all of it into account. A good summary keeps the goal, the decisions and the latest version of the work, and drops the back and forth.

Open the chat in ChatGPT and send this as your last message:

Handoff prompt: send this in ChatGPTSummarize this conversation so I can continue it with another AI assistant that has never seen it. Write it as a briefing, in this order:
1. Goal: what I'm trying to get done, in one or two sentences.
2. Background: the facts, numbers, names and limits I gave you.
3. Decisions so far, and the reason for each.
4. The latest version of the work itself (draft, plan, code or list), in full, not summarized.
5. What's still open: questions, next steps, and ideas we rejected.
6. How I like answers: tone, format and length.
Keep my exact wording for anything I wrote. Leave out passwords, account numbers and private details. Put everything in one code block so I can copy it.

Then start a new chat in Claude, paste the briefing, and add one line: "Read this, tell me in three lines what you understood, then wait for my next message." If Claude gets something wrong, fix it there, before you go on.

Copy and paste, or a ChatGPT share link?

For a short chat, select the text and paste it into Claude. A share link (Share, then Create link or Copy link) makes a public page that anyone with the link can read. For a personal account, it's a snapshot: messages you add later aren't included unless you update the link.

Claude can't sign in to your ChatGPT account, so don't count on it opening a share link. Pasting the text is the sure way.

Export a ChatGPT conversation to Claude with your data export

To export a ChatGPT conversation to Claude, or all of them, use ChatGPT's own export. It's the only way to get every chat out at once. On the web:

1. Open your profile menu, then Settings, then Data controls.
2. Under Export data, select Export, then Confirm export.
3. Wait for the email or text. OpenAI says it can take up to 7 days, and the download link expires 24 hours after you get it.
4. Unzip the file. Your chats are in conversations.json, a plain-text data format, and some exports also include chat.html, a basic page that shows the chats in your browser.

Find the chats you need, in chat.html if your export has one or by searching conversations.json in a text editor, copy them into a text file, and upload that file to a Claude chat or project. Claude accepts TXT, HTML and JSON files, up to 500MB per file in a chat and 30MB per file in a project. Uploading only what you need keeps Claude focused and keeps private details out.

A couple of limits. An export can't bring back chats you already deleted. And self-service export isn't available in ChatGPT Business, Enterprise or Healthcare workspaces, so ask your workspace owner instead.

Move your ChatGPT memory to Claude with the import tool

If you want to move your ChatGPT memory to Claude, this is the one official tool. Anthropic's import works on every plan, including Free, on the web and in Claude Desktop.

1. In Claude, go to Settings, then Your Claude (Settings, then Memory, in the older layout), and select Start import.
2. Claude shows a prompt. Copy it into ChatGPT. You can edit it first to leave out anything sensitive.
3. Paste ChatGPT's answer into Claude's box and select Add to memory.
4. Select See what Claude learned about you to check the result.

Two things to know. Anthropic calls memory imports experimental, so Claude may not take in everything. And Claude's memory is built around work topics, so personal details that aren't about work may not stick. To see what ChatGPT has saved before you start, open Settings, then Personalization, then Memory.

Custom instructions, projects and files: what carries over to Claude

Copy your ChatGPT custom instructions into Claude

In ChatGPT on the web, open Settings, then Personalization, and copy your custom instructions. On a phone, they're under Settings, then Customize ChatGPT. In Claude, paste them into Settings, then Your Claude, then Instructions. Claude applies them to every conversation. Read them once after pasting, and rewrite any line that names a ChatGPT feature.

Rebuild a ChatGPT project in Claude

A ChatGPT project keeps chats, files and instructions together, and Claude has projects that work much the same way. To rebuild one:

1. In ChatGPT, open the project and download each file from its sources list.
2. Copy the instructions from the project's menu, under Project settings.
3. In Claude, create a project, upload the files (up to 30MB each) and paste the instructions.
4. For the project's important chats, run the handoff prompt and add each briefing to the Claude project as a file.

Free Claude accounts can have up to five projects. Images you made in ChatGPT can come along as uploads, and Claude can read them, but Anthropic says Claude doesn't generate photos or illustrations.

How to use ChatGPT and Claude together instead of switching

You don't have to pick one. You can use ChatGPT and Claude together: one for images and voice, the other for long documents. The handoff prompt works in both directions, and Claude can export its memory too. Ask it to write out its memories of you exactly as stored, then paste that into the other app. Our ChatGPT Plus vs Claude Pro comparison shows what each plan is best at. How the two can work with each other is covered in can Claude talk to ChatGPT.

AgentMsgr doesn't move chats from ChatGPT to Claude. It's built for a different problem: when your agents sit together in one AgentMsgr group chat, they all read the same thread, so there's no history to haul from one to the next. You can also connect your own Claude or ChatGPT to AgentMsgr, and the assistant you plan with can post a briefing into that chat and read back what the agents said. Here's how a group chat with agents from two companies runs. On Claude's side, the connection is a custom connector that lets Claude read and post in your agents' chats, on any plan, Free included.
