Add several features to Chrome with this free DeepSeek AI extension

Last year, DeepSeek turned all kinds of heads when it came on the scene and presented itself as a faster, more-efficient alternative to options like ChatGPT and Copilot, all available for free. Some of that hype has worn off since, but DeepSeek is still up there as a top AI chatbot.

If you’re using Google Chrome or any other Chromium-based browser—including Microsoft Edge, Opera, and Vivaldi—then you can actually use DeepSeek directly in your browser via the DeepSeek Assistant extension, available in the Chrome Web Store.

After installing it, click on the blue icon in your browser’s extension bar (next to the address bar). Here you’ll find the input window for making DeepSeek requests. Type in your prompt and submit via the blue paper plane icon, and you’ll get a response shortly after. When you’re done, use the icon at the top-right of the sidebar to close the panel.

Other things you can do include clicking on the button below to delete the current conversation and start a new chat with the AI, clicking the sun icon to switch between light and dark modes, and using the third icon to launch the current request in a new browser tab.

The DeepSeek Assitant extension has even more features than simply chatting with the DeepSeek AI. If you select text on a web page, for example, you get a small “mini bar” pop-up with options like translation. You can select the target language via the drop-down menu, and the extension will immediately show the translated text.

Other features include summarizing and/or paraphrasing longer texts, grammar checking, answering questions, and explanations.

And lastly, if your search engine of choice is Google, the extension also inserts a DeepSeek widget at the top-right of Google Search. Use the “Ask AI” button to get a summary of the current search results.
