The data

AI detection is not a future problem. It's today's problem.

Detection tools have crossed 99% accuracy. Unedited AI content is flagged automatically. The agency workflow forces humanization — but humanizing without keyword protection destroys the SEO value your team spent hours building.

Built for the way agencies actually work

Not a browser tool you run one article at a time. A system you integrate once and run at scale.

account_tree

Per-Client Keyword Profiles

Maintain a separate keyword shield list for every client. Their protected terms are applied automatically to every content batch — no manual marking per article.

api

API With shield_terms

Pass your keyword profile as shield_terms in every API request. Protected phrases survive the rewrite across any volume of content, consistently.

Bulk Processing at Scale

Client delivery

Content exports to each client's CMS via JSON. Structured output maps directly to CMS fields. No copy-paste.

HumanizerPro vs. the alternatives

Generic humanizers (Undetectable.ai, QuillBot) rewrite keywords the same way they rewrite everything else. Manual editing doesn't scale. Here's how the three approaches compare.

Criterion
Manual editing
Generic humanizers
HumanizerPro API
Keyword protection
Manual review after rewrite — errors still reach publication
No protection — keywords rewritten like any other phrase
Phrase locking before rewrite — errors structurally impossible
Volume capacity
~10–15 articles/day per editor
Unlimited volume, but keyword losses scale with it
Unlimited — API processes hundreds per batch overnight
Per-client profiles
Editor memorizes or copies a list each time
Not supported — one-size settings for all clients
JSON profile loaded automatically for every batch
CMS integration
Copy-paste per article
Copy-paste or basic export — no structured output
JSON export pipes directly into CMS fields
Audit trail
None — no record of what changed
None — no verification that keywords survived
Full log: original, humanized, shield_terms used, verification result
Monthly cost at 100k words
~$2,500–$5,000 (editor time)
$20–$100/mo — but keyword losses require manual recovery
Pro plan — automated verification, zero recovery overhead

Generic humanizer category includes tools that do not offer configurable keyword protection per request or per client.
