DragonflAI prevents indecent or illegal images and videos from leaving users' mobile devices by running moderation on-device before content is uploaded. It uses compact, edge-optimized machine learning models and mobile inferencing to classify media in milliseconds, returning results in ~30ms. The offering is a B2B SaaS/edge-ML product aimed at moderation companies and social networks, and integrates with existing moderation pipelines and upload APIs. By performing inference on-device it preserves user privacy and reduces cloud compute and bandwidth costs compared with cloud-only moderation. The technology targets large-scale platforms that need fast, private, and cost-efficient pre-upload content filtering.
