详情介绍:

CAPTCHAs interrupt every visitor to catch a few bots — and modern bots solve them anyway. useHUMA takes the opposite approach: it observes how a visitor behaves (mouse rhythm, typing cadence, scroll patterns, touch physics) and scores the probability that a real human is present. Real visitors feel nothing. Bots get blocked. What it protects:

Comments — spam comments are rejected before they reach your moderation queue
User registration — fake account signups are stopped at the door
Contact Form 7 — form spam is invalidated on submission (if CF7 is installed)

Why site owners choose it:

Invisible — no checkbox, no image puzzles, no friction for real visitors
Privacy-first — zero PII: no keystroke contents, no names, no fingerprinting databases; only statistical aggregates of interaction patterns
Fail-open by design — if the verification service is ever unreachable, your forms keep working
Tells you when it was an AI agent — not just bot or human. Playwright, Puppeteer, browser extensions and computer-use agents come back with their own verdict, on every plan including the free one
One setting — paste your API key and you're protected

You'll need an API key from humaverify.com. It is free and it stays free: every account starts with 14 days of the Starter plan and then settles on the Free plan, 1,000 verifications a month, for ever, no credit card. Most small sites never need more than that.

安装:

Install and activate the plugin.
Get a free API key at humaverify.com/signup. No credit card.
Go to Settings → useHUMA, paste your API key, and choose what to protect.
Done — protection is invisible from this point on.

常见问题:

Will my visitors see a CAPTCHA or checkbox?

No. Verification is completely invisible. Visitors just use your site normally; the behavioral score happens in the background.

What data is collected?

Only statistical aggregates of interaction timing (e.g. "how much did typing rhythm vary"), never the contents of what a visitor types, and never biometric identifiers. See the External services section for the full list.

What happens if the useHUMA API is down?

The plugin fails open: submissions are allowed through. An outage will never lock real users out of your forms.

What is strict mode?

By default, submissions without behavioral signals (e.g. from visitors with JavaScript disabled) are allowed. Strict mode rejects them — which blocks direct-POST bots completely, at the cost of also blocking no-JavaScript visitors.

Is it really free, or is it a trial that ends?

Both. Every account gets 14 days on the Starter plan, then settles on the Free plan and stays there: 1,000 verifications a month, no expiry, no card, with the AI-agent verdict included. A thousand a month is enough for most personal and small business sites. If your forms see more than that, the paid plans start at $49 a month, and the same API key keeps working.

Does it work with caching plugins?

Yes. The collector runs client-side after page load, so full-page caching doesn't affect it.
