What AI Search does

AI Search lets you describe what you are looking for in everyday language instead of remembering exact file names or adding keywords to every photo first.

Examples of searches:

• “dog running on the beach”
• “birthday cake with candles”
• “mountain landscape in winter”

LunaFinder compares your description to visual understanding of your images and shows the best matches—up to 50 results per search.

Privacy

AI Search runs on your Mac. Your photos are not sent to LunaFinder’s servers for searching. The app downloads a search model once (about 600 MB) and builds an index of your opened library locally.

You still need internet for the first-time model download and for license activation; day-to-day browsing and tagging work offline once setup is complete.

Optional feature

AI Search is optional and marked Experimental in Settings. You can use LunaFinder fully with manual keywords and filename search only.

How it fits with keywords

Approach	Best for
Keywords you add	Precise, permanent labels you control (portfolio, client-acme, posted-ig)
AI Search	Exploratory finding when you have not tagged everything

Many users combine both: tag keepers and favorites, use AI Search to rediscover older shots.

Requirements

1. Enable AI Search in Settings
2. Wait for the model to download and show ready
3. Index images in your opened folder (happens automatically over time; you can also reindex manually)
4. Turn on AI Search in the header and type a description
