What is deepseek-memory?

DeepSeek Memory is a browser extension for Chrome that adds two things DeepSeek Chat does not have on its own: a way to remember facts about you between conversations, and a way to load custom instructions that stay active while you chat. By default, DeepSeek forgets everything once a conversation ends. This extension watches your chats and automatically saves useful facts, like your name, your preferences, or details about a project you are working on. Those facts get quietly added back into every new chat, so DeepSeek keeps talking to you as if it remembers who you are. You can open a settings panel at any time to view, edit, delete, export, or import the stored memories, and the whole system works regardless of what language you type in. The second feature is a skill system. You can upload markdown files that describe instructions or workflows you want DeepSeek to follow, then turn each one on or off individually. Every enabled skill gets sent along with your messages, so DeepSeek behaves according to whatever rules you have written. Both features live inside a settings modal built to match DeepSeek's own interface, with separate tabs for general settings, skills, and memory. Everything the extension stores stays on your own device using Chrome's local storage. It does not send your memories, chats, or browsing activity to any outside server, and it only ever talks to the chat.deepseek.com page you are already using. There is no analytics or tracking built in. To install it, you clone the source code, install its dependencies with npm, build it, and load the resulting folder into Chrome through developer mode. Under the hood it is built with Svelte 5 and Vite. This is an independent, community project. It is not made, endorsed, or supported by DeepSeek or DeepSeek AI in any way, and it is released under the MIT license.
