Open Notes

AI-powered moderation for communities

Detection is cheap. Manual review is not.

Our AI detects harmful content and handles most cases. Your community resolves close calls and disputes — no expensive moderators needed.

Moderation that scales — AI + Community Notes

The Problem

Detection isn't the bottleneck anymore. The real cost comes from review.

AI can flag hate speech, spam, NSFW content, and policy violations at scale. But deciding what to do with borderline content — and handling user disputes — still requires expensive human moderators.

Where moderation budgets actually go

Close calls / ambiguous decisions~55%
Appeals & disputes~20%
Inconsistent decisions & rework~13%
Queue management overhead~12%

Based on public transparency reports from Meta, TikTok, YouTube, and X Corp., and industry operational benchmarks.

The Cost Reality

Expert review costs 500–1,000× more than AI detection.

In most systems, 60%+ of flagged content is routed to expensive expert reviewers. Community review handles the same cases — for virtually nothing.
