Amazon Rekognition Content Moderation vs CleanSpeak

Amazon Rekognition Content Moderation uses machine learning and managed APIs to automate moderation of images and videos. It detects categories including explicit or suggestive content, violence, drugs, tobacco, alcohol, hate symbols, gambling, and disturbing content. Results include labels, confidence scores, and video timestamps, which can support granular rules based on a hierarchical taxonomy. Customers can train a Custom Moderation adapter for image analysis with as few as 20 annotated images. Low-confidence predictions can be sent to Amazon Augmented AI for review by internal teams or third-party reviewers. For stored video, StartContentModeration analyzes content in an Amazon S3 bucket and publishes completion status to an Amazon SNS topic. AWS charges according to images or video duration processed, with no minimum fees or upfront commitments. The Free Tier lasts 12 months from account creation and includes 60 video-analysis minutes per month and two custom-adapter training hours monthly. Images and videos passed to the service may be stored and used to improve it unless customers opt out; stored content is encrypted at rest using AWS KMS.

CleanSpeak is a configurable moderation toolset for services that need to filter or review user content. It filters text, images, and video, and can moderate audio but does not filter it. Moderation queues let teams review and escalate material, while custom rules can automate actions by content source, rate users, and trigger actions from those ratings. Editable blocklists detect negative terms and phrases, including altered forms intended to bypass filters. The product includes 22+ base language lists that customers can change or supplement. Tunable text, image, and video models integrate Google Perspective and SightEngine; reports cover moderator activity, content searches, and term or model frequencies. CleanSpeak is available as managed cloud service or as server software installed and maintained by customers. Its synchronous REST APIs return JSON for real-time integration across content filtering, moderation, and user management. The company says one server can filter 10,000 or more messages per second. It serves use cases in apps and gaming, retail and hospitality, and enterprise settings. The advertised trial lasts 30 days and requires no credit card; pricing is available on request.
