You have a great discussion going on – it was very interesting to gather some insights about your opinions on Turnitin and PlagScan. As PlagScan's communications manager, please allow me to comment on the aspects mentioned above about PlagScan's compatibility with Moodle, switching from Turnitin and pricing:
We are aware of some imperfections of our code that have impaired PlagScan’s compatibility with Moodle. We have spent much time focusing on improving other aspects of our software in the past. However, we have noticed a vast increase in traction with our Moodle integration recently and are now rebuilding the code to enable a flawless integration to Moodle as one of our top priorities. If anyone is interested in receiving closer details or receiving access to a beta-test, please feel free to get in touch with us at firstname.lastname@example.org. We also value feedback and are always open to new ideas and suggestions.
PlagScan is very flexible and open to helping customers. We have assisted multiple users to switch form their previous plagiarism software to our service by offering a script to move existing archived documents into the comparison pool. We have received a lot of positive feedback from customers who switched to PlagScan. A majority of customers who switched, have remained with our service.
We actually offer a special discount for users who intend to switch to PlagScan from are a different plagiarism software, such as Turnitin.
Our pricing is fair and customized to our user’s needs. Particularly the pricing packages for organizations are well-calculated. Users can always reach out to us if they have any concerns, especially if they feel inadequately charged.
I hope this helped. Feel free to reach out if you have any questions!
