Frequently asked questions

5 Answers
How does the AI Text Detector spot AI-generated writing?
The engine evaluates multi-dimensional forensic linguistic markers: burstiness (sentence length variance), token predictability (perplexity approximation), synthetic transition clichés ("delve", "tapestry", "multifaceted", "it is worth noting"), participial clause cadence, and lexical richness.
Can this detector identify specific AI models like ChatGPT or Claude?
Yes. Different large language models exhibit distinct stylistic fingerprints. For example, OpenAI models frequently rely on academic filler words ("delve", "tapestry", "testament to"), while Anthropic Claude models display characteristic conversational hedging ("thoughtful and nuanced", "essential to recognize").
What is "burstiness" and why does it distinguish humans from AI?
Burstiness measures the variance in sentence length and structure. Human authors naturally vary their rhythm — interspersing short, punchy statements with longer, complex clauses. In contrast, autoregressive language models produce sentences of remarkably uniform length and balanced clauses.
Is my text private and confidential?
Yes. Input text is analyzed in-memory to compute forensic metrics and sentence scores. It is never stored, sold, or used to train AI models.
How does Sealed Rose prevent AI impersonation on its platform?
Every creator on Sealed Rose undergoes NIST SP 800-63A-aligned government ID verification and biometric liveness checks. AI chatbots, agency ghostwriters, and automated account management tools are strictly prohibited from operating any creator inbox.
