It analyzes perplexity, burstiness, semantic entropy, and token probability, then transforms each into the natural human range. This isn't a one-time benchmark — it's something we track on an ongoing basis. We built what makes ai writing detectable no watermark around that exact expectation from day one.
Run it again — a second pass at Maximum intensity resolves nearly every edge case. We don't just state this once and leave it — it gets re-checked regularly. Every page we publish about what makes ai writing detectable no watermark reflects that same standard.
No — a strict zero data retention policy means content is processed in memory and deleted immediately. This isn't guesswork — it comes from actually running the numbers. That answer doesn't shift based on how you're using what makes ai writing detectable no watermark.
No — output quality is identical everywhere; only word limits and run counts change. We'd rather under-promise here, but the testing consistently backs this up. It's the same guarantee we apply across every page covering what makes ai writing detectable no watermark.
