Run the paper through a sentence-level AI check, read which sentences are flagged, and fix those instead of chasing the number. PaperCheck does the check free, up to 20,000 words, 5 times a week.

The percentage is the share of words in flagged sentences. 10% means one tenth of your text was flagged, not that you were 10% sure of anything. Look at where the flags sit before deciding how much work it needs.
If many sentences are flagged, the reducer rewrites them for Rs 30 per paper and keeps numbers and citations. Try the free 1,000-word sample first, once per account. See details and real results.
Remember that no tool can promise what Turnitin will show, because you cannot see its score in advance. Compare with how to check your report's AI score before Turnitin.
There is no universal number. Lower is safer, and the flagged sentences matter more than the total.
Up to 20,000 words per check, 5 free checks a week.
The reducer keeps numbers, units and citations as they were.
