Pre-built integrations for popular platforms plus a documented API let teams add human verification to a site or app in minutes.
adCAPTCHA says it collects interaction data only to confirm humanness, with no personal data collection and no cookie use.
adCAPTCHA takes a different angle on the oldest friction point on the web: proving a visitor is human. Rather than serving distorted text or grid puzzles, it presents short image or video challenges drawn from media the site owner uploads. A visitor completes a natural interaction with that media, and the system decides whether the session looks human. The company positions four layers of security behind a single, fast interaction so that the challenge looks and feels effortless while still filtering out scripts and automated abuse.
The engagement angle is what separates it from commodity CAPTCHA vendors. Because the challenge surface belongs to the customer, the same screen used to verify traffic can showcase a product, a campaign, or a sponsor's placement. That turns a step users normally resent into one they may actually notice, and it creates an inventory an e-commerce store, publisher, or support portal can monetize or use for first-party messaging.
Implementation is designed to be quick. There are pre-built integrations for common platforms and a documented API for custom front ends, both supported by a dashboard where teams upload media, review activity, and tune behavior. adCAPTCHA states that it collects interaction signals only and does not use cookies, which is a meaningful selling point for teams tightening their data practices. Pricing is quoted per deployment through sales.
Place a verification step that keeps bots out of account creation, coupon abuse, and inventory scraping while keeping the checkout experience pleasant.
Use visitor challenges to surface sponsored or first-party video and image placements instead of a blank puzzle screen.
Filter automated registrations and spam submissions on forms, comment threads, and support portals with a low-friction challenge.
Drop in a pre-built integration or use the API to add verification to custom front ends, then manage settings from the dashboard.
