PageGuide: Browser extension to assist users in navigating a webpage and locating information
Abstract
Users browsing the web struggle to locate relevant information on cluttered pages and to complete web navigation tasks. Current web agents can answer questions and automate actions, but return answers without showing where the information comes from, forcing users to manually verify results and blindly trust every automated step. We present PageGuide, a browser extension that grounds LLM answers in page content (e.g. HTML DOM elements, text, maps, images, charts), via two features: FIND, which highlights supporting evidence in situ on a page, and GUIDE, which guides users across pages with evidence captured at each step. In a within-subject study (N=92), PageGuide improves overall verification accuracy from 65% to 77% and reduces verification time from 73s to 67s across FIND and GUIDE tasks. PageGuide also reduces manual search effort and improves users' perceived support for verification. Code is available at https://pageguide.github.io/.
