Highlighter.pro

This is a Chrome extension written by me, that works as a highlighter on webpages.

I was looking for an extension with open code, that can be installed from source code as like as from the Chrome Web Store(click on this link to install it), that does not collect any data from user, and, as is often the case, I ended up writing my own.

It's very fast, very lightweight and does not overload your browser with heavy scripts.

Here you can see how it works:

Functionality

• You can add (and remove) highlights on web page using browser's context menu.
• This extension uses side panel to show list of highlights and notes
• You can add or edit notes to highlights in side panel
• Notes to highlights can be written in GitHub flavored Markdown. It means you can format text, add notes, task lists, code blocks etc.
• Highlights and notes can be saved to a backup file and then restored on another computer on in another Chrome browser. For this use extension's options page.
• On extension's 'options' page you can remove all your highlights and notes in current browser (it is recommended to save a backup file before)
• Code is open sourced and published on GitHub and GitLab

How to save and restore backup

Right-click on the extension icon > choose 'options' > use corresponding buttons to save and restore backup file.
