Matt Wolfe built a Chrome extension called PageBrief in ten minutes using the GLM 5.2 model. He shows the exact prompt that generated the code, walks through installing it in developer mode, and demonstrates it summarizing a page and extracting key links and action items.
Okay, this is so easy that it doesn't seem real. I made my own customized Chrome extension in like 10 minutes. So I used GLM 5.2 from ZAI. It's an open weight model, open source model that's just way cheaper to code with than other models, but it works just as well. Now this isn't sponsored, it's just a really great AI. Here's the prompt that I used. Build me a Chrome extension called PageBrief. It should summarize the current webpage, extract action items, pull out key links, let me copy everything as markdown, include a clean popup UI, and generate all the files I need. It made me all these files that I can go and use to install this extension. I just opened Chrome, went to Manage Extensions, turned on Developer Mode, clicked Load Unpacked, and selected the files. Now the extension is installed just like any other Chrome extension. And I tested it on one of these articles. I clicked the extension and instantly got a summary of the page, the key takeaways, important links, and a button to copy everything as clean markdown text. I recommend saving this video so you can make your own customized Chrome extensions. And don't forget to follow me for more AI tips.
