How It Works
This calculator simulates how major AI detection tools would score your content. It analyzes multiple linguistic patterns that AI detectors look for: perplexity (word predictability), burstiness (sentence length variation), lexical diversity, transition phrase overuse, and structural uniformity.
Each simulated detector uses slightly different weighting and thresholds. GPTZero emphasizes burstiness and perplexity, Originality.ai looks at sentence patterns and vocabulary choices, Turnitin focuses on predictable academic phrasing, and ZeroGPT analyzes statistical patterns in word choice. Your overall bypass probability represents the likelihood of passing the majority of these detectors.
Use the detector-specific breakdown to understand which tools might flag your content and why. The improvement recommendations help you rewrite sections to increase your bypass probability.
Frequently Asked Questions
How accurate are these predictions?
+
This calculator simulates detector behavior based on known patterns and publicly documented algorithms. Real detectors constantly evolve and may use proprietary techniques. Treat results as estimates – a high score suggests you are likely to pass, but is not guaranteed. Always test with actual detectors for critical use cases.
What is a good bypass probability?
+
Above 70% suggests your content will likely pass most AI detectors. 50-70% indicates mixed results – some detectors may flag it. Below 50% means most detectors will likely identify it as AI-generated. Adjust your writing based on the detector-specific breakdown.
Why do different detectors give different scores?
+
Each detector uses different algorithms and thresholds. GPTZero emphasizes sentence-level patterns, Originality.ai focuses on vocabulary predictability, Turnitin looks for academic writing patterns, and ZeroGPT uses statistical analysis. A piece of text might pass one detector while failing another due to these different approaches.
Can I guarantee 100% bypass?
+
No tool can guarantee 100% bypass of all detectors. Detection technology constantly evolves, and some detectors use proprietary methods. The best approach is to combine AI tools with substantial human editing, add personal voice and specific examples, and verify with actual detector tools before submission.
How can I improve my bypass probability?
+
Focus on the recommendations provided: vary sentence lengths dramatically (mix 5-word and 30-word sentences), reduce formal transitions, add personal anecdotes, use contractions, include occasional imperfections, vary paragraph structure, and replace predictable vocabulary with unexpected word choices. Manual editing is more effective than automated humanization tools.
