CommunityEventDedup: Duplicate Event Detector
Automatically detects and merges duplicate community events across Facebook, Eventbrite, Meetup, and local websites so residents see one canonical listing instead of 5 copies.
The Problem
Community organizers and residents waste hours finding the same event posted multiple times across different platforms. A yoga class gets listed on Facebook, Eventup, the community center website, and Nextdoor simultaneously, fragmenting RSVPs and confusing attendees about which is the 'real' event. There's no tool that watches these platforms and consolidates duplicates in real-time.
Target Audience
City governments, neighborhood associations, and local event aggregator sites (Eventive, Do512, etc.) that want to power accurate community calendars without manual deduplication.
Why Now?
Community event discovery is booming post-pandemic, and fragmentation across platforms is now the #1 pain point. LLM embeddings make fuzzy matching trivial compared to 2-3 years ago.
What's Missing
Event platforms treat dedup as internal-only (protecting their silo). No standalone tool exists because it requires working with multiple APIs simultaneously—something AI tools now make trivial for solo builders.
