I built a Chrome extension that turns webpage highlights into clickable edge markers
Hey everyone,
I built a small Chrome extension called Beacon.
The idea came from my own research workflow. I use AI tools and long webpages a lot, but while reading I often run into extra concepts I want to revisit later. Existing highlighter tools are great for saving highlights, but I wanted something that stayed visible on the page while I was reading.
Beacon lets you:
- select text and highlight it with a shortcut
- see each highlight as a small color marker on the right edge of the page
- click a marker to jump back to the original text
- hover over a marker to preview the highlight
- keep highlights saved locally for that page URL
It’s mainly useful for long articles, AI answers, technical docs, API references, reports, and research pages.
This is v1.0, so I know compatibility may not be perfect across all webpage layouts yet.
I’d love feedback from other extension users/builders:
Would you prefer this kind of tool to stay minimal, or should it eventually support export, tagging, color categories, or sync?
