How to fix lines flagged as AI-written

Lines get flagged when they're generic: smooth, evenly paced, and true for any paper on that topic. The fix is to say what's specific to your work, mix short and long sentences, and drop the stock phrases.

What makes a line read as AI

Generic claims like this approach plays a crucial role, filler words like moreover and furthermore, lists of three adjectives, and long stretches of sentences that are all the same length. None of that is wrong on its own, but together it reads like it could be from any paper.

What actually works

  1. Swap the general claim for your actual result: a number, the dataset, the part you used.
  2. Say who did it: we measured, the model picks.
  3. Split one long sentence into a short one and a longer one.
  4. Drop moreover and furthermore when the link is already obvious.
  5. Add one thing only you know: what broke, what you changed, what surprised you.

Using ChatGPT or Claude to help

Paste the flagged lines with their paragraph and ask it to make each line more specific to your work without changing any facts or citations. PaperCheck's fix report does this for you: every flagged line, why it was flagged, and the paragraph around it, in one block you can paste.

Then check again

Rewriting flagged lines usually brings the score down, but the only way to know by how much is to check the new version.

Common questions

How do I make my writing sound less like AI?

Make each line about your own work: your numbers and what you saw, mix sentence lengths, and drop phrases like moreover and plays a crucial role.

Will paraphrasing remove an AI flag?

Just swapping synonyms often doesn't. Rewriting the line around a real detail from your project changes it much more.
