Privacy-first human verification that swaps annoying puzzles for engaging images and video.
Verify visitors with short image and video interactions instead of text or grid puzzles, using media you upload through the dashboard.
Multiple detection layers run behind a single interaction to catch sophisticated bots without adding friction for genuine users.
Turn the verification moment into a positive touchpoint by featuring your own media, or open the space to advertisers.
Pre-built integrations for popular platforms plus a documented API let teams add human verification to a site or app in minutes.
