It comes with site-specific logic for automatically extracting key information, such as video playing time on YouTube, course info and reference on edX, metadata on Kindle notes etc. This can be easily extended to add extraction logic to any web page.

This is useful for learning, research, and saving interesting ideas for creative work.

You can also search / look up existing content (defaulting to the Rumin backend) using the “Lookup” tab.

Page-specific Parsing Logic

The extension comes with page-specific logic extracts the key metadata, and turns page content into structured data. This way, you don’t have to copy and paste back and forth.

Currently supported sites include:

  • YouTube video
  • Skillshare
  • edX
  • Linkedin Learning
  • Netflix
  • Messages on Slack
  • Comments on Reddit and more

It is easy to add support for automatic extraction on more sites. All you need is logic to check the url (or content) of the current page, and add logic to update customFields accordingly.
