Immich Duplicate Reviewer — open-source tool with AI-powered scoring

[Eth3rkni6ht]

Hey everyone,

I built a desktop tool to help with duplicate photo management in Immich and wanted to share it with the community.

Immich's built-in duplicate detection is great at finding the groups, but it leaves all the decisions to you. This tool scores each photo automatically so the best copy is obvious at a glance.

Scoring factors:
🔍 Sharpness (scale-invariant, so a blurry small image can't outscore a sharp large one)
👤 Face detection — runs both Immich (InsightFace) and Google MediaPipe independently, merges results so faces missed by one engine are caught by the other
👁️ Open / closed eyes
😊 Smiles
📐 Resolution & file size
⭐ Star ratings
All weights are configurable sliders
Other features:

Side-by-side viewer with click-to-zoom and drag-to-zoom — synced across all images in the group so you can compare the same spot on every copy
Annotation overlays (faces, eyes, smiles) — toggleable
One-click actions: Keep best, Keep all, Stack as versions, Delete all, Skip
Keyboard shortcuts for fast batch processing
Auto-select when score gap is large enough
Album & date range filters
Connects via Immich API key
