Four small models, all on your iPhone
Munin reads your library only with your permission, and only on the phone. It uses a small vision-language model to read and describe your shots, a text embedder and an image-text model to find likely matches, and a reranker to put the best ones first.
- The models
- Munin's on-device AI models (about 4 GB) are delivered by the App Store with the app, from Apple's servers, during installation; Munin itself sends nothing. Wi-Fi is recommended.
- After that
- Once the models are on your iPhone, search and answers work offline.
- Indexing
- Munin reads your library in the background while it is open, and can continue while your iPhone is charging.
- Requires
- iOS 26 and an iPhone with enough memory for on-device AI. The supported models will be listed on the Support page before release.
