The captchator gem provides a seamless captcha interface for Rails applications with easily readable captcha images. Thanks to captchator.com/ for the library.

Add it to your Gemfile:

gem 'captchator'

In your view

<%= captchator_tags %>

In your controller

verify_captchator # returns true or false

-or- if you would like seamless integration with your model errors you can call

save_with_captchator(@my_model)
