birdpreen 0.2.2

Scan macOS Photos library, detect and identify birds, write species captions

preen

Groom your photo library — automatically find and name every bird.

Preen scans your macOS Photos library, detects birds with YOLO, identifies species with SuperPicky's OSEA classifier (10,964 species), and writes "中文名 (English Name)" as captions — visible on iPhone.

Features

• Scans entire Photos library including iCloud photos
• YOLO multi-bird detection — finds all birds in a photo
• OSEA species identification with GPS-based eBird regional filtering
• Writes captions via persistent Photos.app connection (photoscript)
• SQLite checkpoint — pause/resume, incremental or full rescan
• Deduplicates species in multi-bird captions

Requirements

• macOS with Photos.app
• Python 3.11+

Installation

pipx install birdpreen

Or with pip:

pip install birdpreen

On first scan, model files (~260 MB) are automatically downloaded from HuggingFace.
