What is Sightengine?
Protecting your platform and users from harmful, illegal, and inappropriate content is essential, but the sheer volume of user-generated media and text can make manual moderation slow, costly, and inconsistent. Sightengine offers a powerful suite of APIs designed to automate content assessment, filtering, and moderation across images, videos, and text. With Sightengine, you can build an efficient, scalable, and privacy-compliant content analysis pipeline that helps you enforce your terms of service, safeguard your community, and focus on growing your platform.
Key Features:
🖼️ Comprehensive Image & Video Moderation: Instantly detect a wide range of unwanted visual content across 110+ categories, including nudity, violence, hate, drugs, weapons, and restricted activities. Our models are context-aware and highly customizable, allowing you to fine-tune detection thresholds and rules to match your specific community guidelines. This helps you quickly identify and flag content that violates your policies.
✍️ Robust Text Moderation: Automatically screen user-generated text in messages, comments, profiles, and reviews for profanity, hate speech, sexual content, and more. Our API also detects personal information (PII), links, and usernames, and is designed to catch attempts by users to circumvent your filters using variations or obfuscation. You can protect your users and brand from abusive or spammy text interactions across multiple languages.
🤖 AI-Generated Content & Deepfake Detection: Authenticate media by automatically identifying images generated by popular AI models (like MidJourney, DALL-E, Stable Diffusion) and detecting sophisticated manipulations like face swaps (deepfakes). Leveraging pixel-based analysis and specialized models, this capability helps you combat the spread of misinformation, fraudulent content, and image-based abuse.
🙈 Automated Video Anonymization: Enhance user privacy and streamline compliance by automatically detecting and blurring or masking faces (optionally focusing only on minors) and other Personally Identifiable Information (PII) like phone numbers, email addresses, or license plates within videos and live streams. This allows you to process video content while protecting sensitive data.
