Griefy helps you improve your work—not hide how it was created.
We believe in responsible academic writing. Griefy is designed to support ethical revision, not evasion.
Supports ethical writing
Griefy helps you identify and fix potential concerns. It does not complete work, provide answers for submission, or circumvent academic policies.
Encourages proper citation
Our tools help you verify that sources are properly cited and referenced, reducing the risk of unintentional plagiarism.
Treats AI results as estimates
AI-writing indicators are probabilistic. Scores are not definitive determinations. Always interpret results alongside your own knowledge and your school's policies.
Promotes original analysis
Griefy encourages you to strengthen your own academic voice. It highlights areas where your writing can be more original and analytical.
Does not guarantee outcomes
Griefy does not guarantee grades, acceptance, detection outcomes, or that your paper will pass any specific review tool.
Follows school policies
We encourage all members to understand and follow their institution's and instructor's specific policies regarding AI use, citation, and academic integrity.
AI detection is probabilistic — no tool can guarantee 100% accuracy. Griefy uses our enterprise AI detection partner as the authoritative AI-detection engine, returning a single probability with a confidence level (low, medium, or high). Claude then flags specific passages using six-signal analysis (perplexity, burstiness, lexical diversity, structural predictability, hedging-language authenticity, and transition uniformity). Use results as guidance to review your own writing — not as proof of intent.
AI Detection Sensitivity Levels
Choose the level that fits your situation. You can change it before every check.
| Level | False positive risk | Best for |
|---|---|---|
| Conservative | Very low | First drafts, low-stakes checks |
| Balanced | Low (default) | Most academic submissions |
| Strict | Slightly higher | High-stakes, catches rewritten AI |
What Griefy Will Never Do
- Claim to make AI content "undetectable"
- Guarantee a grade outcome
- Store your paper beyond 30 days
- Share your paper with your institution
- Use your paper to train AI models
The AI Rewriter's goal is to help you express your own ideas more clearly in your own voice — not to deceive academic integrity systems.
