If you want to fix an AI score in a long thesis or project report, PaperCheck checks it free and rewrites only the flagged sentences for Rs 30 per paper, then re-tests the result.

A thesis has numbers, tables, citations and technical terms that must not change. A tool that rewrites a whole document can damage them. Rewriting only the flagged sentences and keeping the rest as you wrote it limits that risk.
The AI check is free (5 checks, up to 20,000 words each) and shows the flagged sentences. The reducer costs Rs 30 per paper and rewrites only those sentences, keeping numbers and citations. Full details and results.
Some universities limit AI help in submitted work. Read your institution's rules; a lower score does not change what the rules say.
It does a similar job for academic papers and is not affiliated with StealthWriter. It checks your paper free and rewrites the flagged sentences for Rs 30.
Yes. A free check takes up to 20,000 words and the reducer works best on the whole report rather than a short piece of text.
No. Numbers, units, citations like [3], acronyms and technical terms are kept exactly.
