Public studies show −15% to −40% conversion on forms protected by reCAPTCHA or hCaptcha. You pay twice: in friction and in lost signups.
Your visitors train Google's models for free — Street View, image labels, reCAPTCHA v2/v3 — and their behavior is shipped off to a third party.
Solver services charge $2 per 1,000 CAPTCHAs. You pay for friction, the bots walk in anyway.
Zero pixels added to your UX. The only thing we reduce is fraud, never your conversion rate.
Same job, opposite philosophy.
| Solution | Visitor friction | Visitor privacy | Modern AI bots | Conversion impact |
|---|---|---|---|---|
| reCAPTCHA v3 (Google) | Moderate (checkbox) | Sent to Google | Bypassed | −15% to −40% conversion |
| hCaptcha | Heavy (puzzles) | Sent to a 3rd party | Partially blocked | −15% to −40% conversion |
| DataDome | Moderate (checkbox) | Sent to a 3rd party | Blocked | −5% to −15% conversion |
Bot Busters | None — invisible | Processed in EU, no PII | Blocked | No forced friction on humans |
Conversion-impact ranges based on public studies of CAPTCHA friction. v1 — to be refined with our own A/B data.
On every session, in the background. Verdict in <50 ms. Invisible when the signal is clear — no puzzle, no checkbox.
Step-up only when the passive verdict is ambiguous. A short mini-game plus one typed answer (paste blocked). We measure timing — never the text.
The engine adapts to new evasion patterns across sessions. Your tenant sharpens over time, without you shipping anything.
One <script>, one POST. Verdict returned as a signed single-use token — verified server-side with your secret key.
Four ways to feel what we do. Same gateway, four different lenses.
Move your mouse, scroll, click — whatever. We score from public signals only. Nothing leaves this tab.
