Why drafts get flagged, even ones you wrote
AI detectors look for text that is very predictable: even sentence lengths, safe word choices, stock transitions. Chatbot output has those patterns. So does careful, formal writing by real students, especially students writing in a second language.
Swapping synonyms does not fix that. It produces text that reads like nobody, and detectors now look for humanizer output too.
What does help is writing that sounds like a particular person. That is what this tool aims for: your rhythm, your vocabulary, your habits, applied to a draft that came out too smooth.
No tool can promise a detector score. Keep your notes, drafts and version history. They are the strongest evidence that the work is yours.
