I like its mobile apps, 24/7 customer support, budget-friendly pricing, and simple user interface.

We’ve been using their forever free plan after our 15-days trial came to an end. Hats off to ProProfs Chat, they offer amazing features and smooth interface for the price they offer. However, we do not require too many features. We just wanted a tool that helps us answer incoming questions from our customer base easily. That’s exactly what we get to accomplish even with the free plan. Great features and easy-to-use interface that’s free - exactly what we wanted. Thank you ProProfs!

User-interface, assessment library, automated grading, instant feedback.
