Course Scrapers CircleCI

A collection of web scrapers for online courses. This gem is intended to be able to scrape hundreds of courses into one aggregated spot.


Add this line to your application's Gemfile:

gem 'einstein'

And then execute:

$ bundle

Or install it yourself as:

$ gem install einstein


Under lib/einstein there are a series of scrapers. Each scraper can be called simply by running Einstein::[SCRAPER_NAME].fetch. This will return a hash with the following keys:

  • course_title (title of the course)
  • course_code (the code of the course, if any)
  • level (the level at which this course is rated, if any))
  • link (link to the course)
  • description (description of the course)
  • image (a url for an image representing the course)
  • price (the price of the course. If none, then "free")
  • syllabus_link (a link to the syllabus for the course, if any
  • department (the department from which this is offered. TODO: map these to a number of sane values)
  • provider (from where did this course come? Harvard? MIT?)


After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to
