Content moderation, image mod. This pain is concentrated among Product teams managing Sendbird chat costs as user conversations scale and creates demand for a focused tool that resolves the gap without requiring a platform switch.

Cross-app communication triage with local processing is a privacy-defensible daily-habit wedge.
