ChatGPT

ChatGPT is OpenAI’s assistant at chatgpt.com. MemoryPlugin gives it long-term memory that carries across your other AI tools, and lets you sync and search your ChatGPT chat history.

​

Set up

The browser extension is the recommended route. It works on the ChatGPT web app in any Chromium browser or Safari.

​

Custom GPT (alternative)

The MemoryPlugin Custom GPT loads your memories automatically, with no extension. It works on the ChatGPT web app and mobile app. To add memory to a GPT you build yourself, follow the Custom GPT Integration guide.

​

What works here

This walkthrough covers both routes: the official Custom GPT (memory travels through GPT actions) and the browser extension on chatgpt.com (injection, auto-inject, AI-driven recall, and chat history sync).

• Memory recall and save. Injected memories give ChatGPT context; new memories are saved back as you talk.
• Chat history sync. ChatGPT is one of the six platforms the extension can sync directly. New conversations are captured for search and recall across your tools. You can also upload a ChatGPT export file instead.
• Extract memory pill. Select text in a chat and click Extract memory to save that snippet.
• Import existing ChatGPT memories. Transfer the memories ChatGPT already stores about you into MemoryPlugin.

Limitations

• The extension does not inject on its own by default. You click the button to activate a chat, or turn on Automatically add memories in new conversations in the extension settings (it injects after a 5-second countdown you can cancel).
• ChatGPT splits large history exports into multiple files (conversations-001.json, conversations-002.json, and so on). Select all of them when you import.
