“My essay got flagged as AI-written even though I wrote every word of it myself — turns out my writing style just reads a lot like ChatGPT's. StudyPilot showed me exactly which sentences were flagged and helped me understand why, so I could explain my writing process to my lecturer.”
“I upload my lecture slides every week and get flashcards + a full revision plan in minutes. Combined with checking my writing before every submission? I genuinely don’t need anything else.”
“Was paying for QuillBot, GPTZero, and a plagiarism checker separately. StudyPilot replaced all three for less money. The grammar checker is better too — my essays read much more clearly now.”
