SuperHumanizer vs WriteHuman

SuperHumanizer

A no-signup humanizer whose whole selling point is beating academic and editorial AI detectors, now with a named operator, a refund policy and paid tiers behind the free box. It is useful for loosening stiff machine drafts you will edit anyway, and reckless for the coursework case it advertises. The free tier is generous enough that paying only makes sense for volume.

Pros

• +No sign-up, no card and a 1,200-word free run with history kept in the browser
• +Handles output from any model and accepts Word, PDF and text uploads
• +Terms name a legal operator, Kamranali Limited, and a 7-day refund rule, which the old address lacked
• +Chrome extension and mobile apps for people who rewrite inside other tools

Cons

• −The domain changed from aihumanizer.io without any notice on the site, which is thin for a product people trust with drafts
• −Zero-percent detection claims are unverifiable and detectors retrain constantly
• −Monthly word caps and per-input limits make the paid tiers less generous than the free box suggests
• −The built-in detector is paid-only, so the free tier cannot check its own output

WriteHuman

As humanizers go this one is unusually transparent about its own scoring, showing per-sentence detection probability instead of a single vague pass mark, and its surface area — extension, mobile apps, API, MCP — is wider than most rivals. The catch is what the tool is for: passing AI-detection checks breaches most academic integrity policies, and no vendor can guarantee any detector's verdict.

Pros

• +Sentence-level detection scores rather than a single opaque verdict
• +Chrome extension, iOS and Android apps, plus a documented API and MCP access
• +Free tier lets you judge output quality before paying
• +Annual billing cuts the effective monthly rate by roughly a third

Cons

• −Request counts and word caps are tight on the lower tiers
• −Detector outcomes are probabilistic and shift as detectors are retrained
• −Use is disallowed by most academic integrity policies
