First of all, this is purely a personal learning project for me, aiming to combine three of my passions: photography, software engineering, and my family memories. I have a large collection of family photos and want to build an interactive experience to explore them, ala Google or Apple Photo features.

My goal is to create a system with smart search capabilities, and one of the most important requirements is that it must run entirely on my local hardware. Privacy is key, but the main driver is the challenge and joy of building it myself (an obviously learn).

The key features I'm aiming for are:

Automatic identification and tagging of family members (local face recognition).

Generation of descriptive captions for each photo.

Natural language search (e.g., "Show me photos of us at the beach in Luquillo from last summer").

I've already prompted AI tools for a high-level project plan, and they provided a solid blueprint (eg, Ollama with LLaVA, a vector DB like ChromaDB, you know it). Now, I'm highly interested in the real-world human experience. I'm looking for advice, learning stories, and the little details that only come from building something similar.

What tools, models, and best practices would you recommend for a project like this in 2025? Specifically, I'm curious about combining structured metadata (EXIF), face recognition data, and semantic vector search into a single, cohesive application.

Any and all advice would be deeply appreciated. Thanks!

I think Immich checks a lot of these

Been running Immich for a couple years now and it has been awesome. There are a few rough edges but I’m sure most of them will be smoothed out by the first stable release.

Haven't had great results with the AI portion though, even with the recommended model. Embeddings seem really poor, and has lots of misses and false positives.

Given how good the new multimodal models are, I've been thinking it would be much better to just have a multimodal model describe the image, and let the searching be done by the already included melleisearch.

That said, due to reasons I haven't had time to mess with it past couple of months, so perhaps something drastic has changed.
