Avoid.so

In the AI humanizer category, Avoid.so stands out for plans with clearly stated word limits at each tier.

Avoid.so is an AI humanizer that rewrites machine-written text so it passes AI detection checks.

The site claims a 99.8% success rate, which is the vendor's own figure and worth testing yourself.

The free plan gives you 600 words with no expiration, capped at 300 words per request, with basic detection avoidance at standard speed.

Paid plans start at $4.99 a month.

Basic adds 10,000 words a month, 500 words per request, advanced avoidance, priority speed, email and chat support and multiple languages.

Pro costs $14.99 and raises that to 50,000 words a month and 2,000 per request, with premium avoidance, the fastest processing, priority support and custom integrations.

The $29.99 Unlimited plan allows 3,000 words per request, full API access and a dedicated account manager.

Words are unlimited, but processing moves to a slow queue after 120,000 words in a month.

The free allowance is small, so expect to judge the output quickly.
