Set up
Install the extension
Install the browser extension and sign in to your MemoryPlugin account.
Open DeepSeek
Go to chat.deepseek.com. A floating MemoryPlugin button appears on the page.

What works here
- Memory recall and save. Injected memories give DeepSeek context; new memories are saved back as you talk.
- Chat history sync. DeepSeek 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 DeepSeek export file instead.
- Extract memory pill. Select text in a chat and click Extract memory to save that snippet.
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.
