The situation
The education platform received a large volume of user-generated content every day — comments, questions, and shared materials — that needed slow, costly manual review, with the risk of inappropriate content reaching a learning environment built for students.
What we did
We built an automated moderation system combining GPT-4 and Claude to analyze every item the moment it's posted, classify it, block violations automatically, and escalate only ambiguous cases to a human reviewer. Redis speeds up processing and a Webhook API keeps the platform integration real-time.
The outcome
Today 95% of content is moderated automatically in under 5 seconds per item, moderation costs are down 70%, and students get a safer, more consistent learning environment.
