thurs is an AI browser assistant that stays on the page you're already looking at. I built a Chrome extension where you select a region of a webpage and talk to Gemini in place, including multimodal screenshot understanding.
Overview
thurs is a Chrome extension for selecting a region of a webpage and talking to an AI assistant without leaving that page.
Problem
Most AI chat lives in another tab. thurs is about asking something about the page in front of you, without the context switch.
Approach
The interaction is selection-first: highlight a region, then talk to the assistant on the same page. That keeps the original content in view while you work.
Technical implementation
I implemented it as a Chrome extension in JavaScript. Region capture feeds multimodal screenshot understanding, then Gemini, so the assistant can respond to what's actually on the page.
