API Pricing & Signup

The difference between an average grammar checker and a state-of-the-art checker is the difference between a customer impressed by the quality of your product or disappointed with its shortcomings. It’s the difference between a customer who converts and a customer who leaves. We are proud to offer a product that reflects positively on your business (as well as ours).


  • Accuracy - state-of-the-art is the phrase we use because we have yet to find a grammar checker that’s more accurate.
  • Latency - 90% of our requests complete in less than 1 second and 96% in less than 2 seconds.
  • Reliability - 99.99+% uptime
