What it really is

StealthWriter.ai — AI text humanizer that rewrites AI-generated content to evade AI detectors.

Our take

StealthWriter.ai is a focused AI-humanization tool: paste AI-generated text, get back prose tuned to pass GPTZero, Originality.ai, and other detectors. DB listed this as $35/mo paid-only — both wrong. Actual entry is $20/mo (Starter), and a genuine free tier (10 humanizations/day, no card required) makes this freemium. The platform layers a built-in V2 AI detector with sentence-level 'Deep Scan' so users can verify their output in the same workflow.

Why we rate it

Rare combo of humanizer + built-in detector in one UI; free tier lowers the barrier; tiered daily limits scale predictably with team size.

The catch

Daily humanization caps on all plans mean heavy users hit limits fast. Input is capped at 5,000 words per submission even on top paid tiers. Aggressive rewriting can introduce awkward phrasing that still needs manual review.

Best for

SEO content teams producing high volumes of AI-assisted articles

Agencies needing batch humanization with built-in detection checks

Freelance copywriters wanting a free entry point before committing

Not good for

Long-form documents over 5,000 words per session (hard per-submission cap)

Teams needing guaranteed brand-voice consistency without post-editing

Enterprises requiring SOC 2 / GDPR-certified data handling with audit trails

Friction report

Time to value

Fast: no credit card needed for free tier; paste text and get humanized output in under a minute.

Scale breakpoint

Daily humanization caps (50–2,000/day by plan) become a ceiling for large agencies; jump from Pro $100/mo to Scale $400/mo is steep.

Walled garden

Moderate: no direct export integrations or public API on standard plans; content must be copy-pasted in and out.
