Protects My Blog from Copyright Issues
Running a tech blog means I often work with guest contributors, and not everyone is upfront about how their content is created. Winston AI’s plagiarism checker gives me peace of mind by scanning each article against billions of sources. One contributor submitted a post that pulled large paragraphs from a competitor’s site—I wouldn’t have known without Winston. The system highlighted the copied parts and linked directly to the original page. This feature alone has saved me from potential legal headaches.

Experiencing ProWritingAid's Compatibility with Google Docs and Excellent Customer Service
Before I subscribed to ProWritingAid, I was curious about its compatibility with Google Docs. I was thrilled to hear that it was indeed compatible! However, I did encounter a few hiccups due to some changes in Google Docs. But the best part? ProWritingAid's team was always there to help me navigate through these issues. I've sent them numerous emails and they've been nothing but supportive and patient. They've been working tirelessly to rectify the situation, which just goes to show their commitment to customer satisfaction. I'm really impressed with their service!
