ModShield helps Reddit moderators reduce moderation workload using AI-assisted triage, rule detection, queue prioritization, and one-click moderation actions with human oversight.

Inspiration

Reddit moderators manage enormous communities with limited tools and volunteer time. Many moderation tasks are repetitive: reviewing spam, low-effort posts, harassment, duplicate content, and rule violations. We wanted to build a moderation copilot that helps moderators review content faster while keeping humans fully in control.

Our goal was not to replace moderators with AI, but to reduce repetitive workload through intelligent triage, confidence scoring, and streamlined moderation workflows directly inside Reddit’s Devvit ecosystem.

What it does

ModShield is an AI-assisted moderation triage system built on Reddit Devvit.

The app monitors new posts and comments, compares them against subreddit rules, and generates moderation recommendations with confidence scores and explanations.

Moderators can:

  • Review flagged content in a clean moderation dashboard
  • Approve or remove content with one click
  • Prioritize high-risk moderation items
  • Track moderation activity through audit logs
  • View moderation analytics and estimated time savings

The system keeps moderators in control through a human-in-the-loop workflow while dramatically reducing repetitive moderation tasks.
