Writing Tips｜How to Make Your Text More Human-like
While Decopy AI Detector is built with advanced technology, no AI
detection tool can be 100% accurate. We strongly recommend not
relying solely on any AI content detector when making decisions
that could affect your academic standing, professional reputation,
or legal responsibilities.
To improve your content’s
originality and reduce AI detection scores, consider the following
practical writing techniques:
- Add personal voice: Share real experiences or personal opinions.
- Be specific: Support your points with data, examples, or quotes.
- Use varied structure: Try rhetorical questions or advanced vocabulary.
- Simplify and paraphrase: Break long sentences into shorter ones.
- Think hypothetically: Use “what if” scenarios to show reasoning and creativity.
- Use active voice: Say “We completed the study,” not “The study was completed.”
- Include expert language: Use domain-specific terms when relevant to sound more credible.
- Quote real people: Expert opinions or interview excerpts add human depth.
