There are a handful of webpages I keep referring back to, often reading the same parts over and over. They may be part of an instruction manual, or other reference material1. And sometimes, while researching an article, I want to highlight sections and phrases to find them more easily. Just like using a highlighter marker on a sheet of paper.
Until now, I’ve never found good way to do it. Apps required me to sign up for an account, or store my highlights on their servers, or pay a subscription. Or the app was just plain clunky. Then I found Highlighter for Safari.
