Using AI to detect and filter harmful, illegal, or policy-violating content at scale. This includes text classification (hate speech, spam, threats), image analysis (NSFW detection, CSAM), and video moderation. Modern systems combine AI classifiers with human review, but the volume of content generated by AI itself is creating a moderation crisis — you now need AI to moderate AI.
Why it matters
Every platform with user-generated content needs moderation, and AI is the only way to handle the scale. But moderation is harder than it sounds — context matters, cultural norms differ, and false positives silence legitimate speech while false negatives let harm through.
