Proofread Bot checks your writing for grammar, style, spelling, statistic and plagiarism issues and gives recommendations to improve your writing. The tool gives you a visual text editing interface and an auto generated textual report for your convenience. The written report contains additional information, such as readability scores. Proofread Bot already has thousands of language rules, and if you have an idea for a new rule or check, please suggest it in the support forums.
Proofread Bot gives you one free report per week, and for more reports you can buy inside the app extra credits for as low as 1 cent per check.
Educational institutions: if you are interested in buying the Proofread Bot app in bulk, please contact me, and I will create a one time paid or subscription package for you.
The first language Proofread Bot supports is English, but more languages are coming.
