Sightengine Review

Sightengine provides content moderation APIs covering 120+ image classes, video, audio, text, deepfake detection, and AI-generated content identification.

Image & Visual Chat

Verdict

Sightengine is a comprehensive content moderation API platform that stands out for its breadth: it covers image, video, audio, and text moderation alongside AI-generation detection and deepfake identification — capabilities few single-vendor solutions match. It targets platforms needing scalable, automated trust-and-safety pipelines at lower cost than human review. The main tradeoff is that it is API-only with no built-in UI, so meaningful engineering effort is required to integrate.
