The bot every mod already begs for, ported to Devvit. One-click install. pHash + text similarity. Modqueue card with one-tap Remove.

We took RepostSleuthBot — a battle-tested Data-API bot serving image-heavy subs since 2018 — and re-platformed it on Devvit with full functional parity. Mods get sub-second post-submit triggers and a quantified time-saved telemetry panel out of the box. No hosting. No PRAW. No deprecation cliff.
