Build a Chrome Extension That Highlights Key Info With AI

Building a Chrome extension with AI that highlights key information on any page gives you a tool that scans articles, reports, and documents and visually marks the parts that matter most: names, dates, statistics, action items, and key conclusions. On aidowith.me, the Chrome Extension route walks you through 14 steps to create this from scratch. You'll build content scripts that parse page text, connect to an AI model for extraction, and render color-coded highlights directly on the page. The route covers manifest configuration, DOM manipulation, text chunking for large pages, and styling overlays that don't break the original layout. AI handles all the coding while you decide what counts as key info for your use case. The full build takes about 4 hours. You'll finish with a personal research tool that works on any website and saves you from reading entire pages when you only need the key points.

Questions

Yes. The content scripts read page text regardless of the site. It works on news articles, blog posts, documentation, reports, and most web-based documents. Sites with heavy JavaScript rendering may need a slight delay for the content to load first, and the route covers how to handle that.

You decide. The default setup highlights names, dates, statistics, action items, and key conclusions. You can customize the extraction rules to focus on whatever matters for your work: financial figures, technical specs, legal terms, or anything else. The route shows you how to adjust the AI prompt.

No. AI generates all the JavaScript, HTML, and CSS. The route explains every file and function in plain language. You make product decisions about what to highlight and how it should look. People with no programming background have built this and use it daily.
