Field notes
Research notes on how AI detection works, where it fails, and how to write with AI responsibly.
Content at Scale is now BrandWell. Its detector gives a color-coded, sentence-level read rather than one score — but the company itself won't put a percentage on its accuracy, and neither will we on its behalf.
Read articleHIX Bypass is a feature inside a 120-tool suite, priced by monthly word quota much like Refrazr — but the suite-vs-dedicated tradeoff and the 'bypass' branding are worth understanding before you pick.
Read articleAIHumanize.io bundles daily AI-detection scans into every tier and resets your word quota monthly. Refrazr sells one-time packs. Here's the real pricing, verified first-party, plus a warning about the near-identical domain names in this space.
Read articleWriteHuman meters requests, then caps words per request on top of that — a ceiling that bites long before the monthly quota does. Here's what that actually costs against a simple word pool.
Read articleStealthWriter meters how often you rewrite. Refrazr meters how much. That single difference decides which one is cheaper for you — and for ordinary volumes the gap is about ten to one.

Read articleGrammarly bundles its Humanizer into a $30/mo platform ($12/mo if you commit annually). Refrazr is a dedicated tool at $6.99/mo or $1.99 packs. Here's the honest comparison.
Read articleTurnitin's AI score and Similarity score are two separate reports, and most students only ever see one of them. Here's what actually shows up, to whom, and a repository-matching angle most guides skip.
Read articleGoHumanize.ai launched in April 2026 with sensible pricing and seven-language support. We tested it, read every page, and wrote what is genuinely good and what is missing.
Read articleUndetectable.ai is the established option at $9.99/mo. Refrazr is the leaner option at $1.99 packs and $6.99/mo. Here is the honest comparison — verified pricing, real tradeoffs, and who should pick which.
Read articleGPTZero is reasonably accurate on raw AI output and unreliable on anything edited, hybrid, or written by an ESL student. We pasted 100 essays and recorded what happened.
