  • Originality: We combine an AI estimate with local heuristics (n-gram repetition, sentence
                  variety). Use as guidance.
    • 

  • Paraphrase: Choose tone and constraints for safer rewrites.
    • 

  • Academic use: Always cite your sources. See what is
                    plagiarism.
