"AI" and "private" appear on nearly every photo app's page now. They can mean very different things. Some apps run the model on your computer and send nothing; some run it on a server; some do part of each. Here is how to check for yourself, the questions that actually separate the options, and a fair look at the main kinds of tool.

## What "offline AI" should mean

For a photo organizer, offline AI means three things:

1. **The model runs on your computer.** It is downloaded once, then searching, face grouping and tagging happen locally.
2. **Your photos, faces and searches stay there.** The index, the face groups and what you typed are stored on your disk.
3. **It still works with the internet switched off.** Not just browsing — search and faces too.

## How to check any app in five minutes

- **Switch the network off** after setting it up, then search and open People. If both still work, the AI is local.
- **Read its list of what it sends.** A trustworthy app can tell you, in a few lines, every request it makes. firelet.media Gallery's is [here](https://firelet.media/help/what-data-is-sent): a licence check about once a month, an update check, and the model downloads when you press the button.
- **Look for an account requirement.** An app that needs you signed in to use your own photos is talking to a server.

## The questions that separate the options

| Question | Why it matters |
|---|---|
| Does it use my folders, or import into its own library? | Imports duplicate your files and make leaving harder |
| Can it write ratings and keywords to XMP sidecars? | XMP is how you avoid lock-in |
| One payment, subscription, or free? | Decide what you'll still be paying in five years |
| Desktop app or a server I run? | A server reaches you anywhere but needs looking after |
| Does it read my camera's files? | RAW support varies widely — check your own files in a trial |

## The main kinds of tool, fairly

- **Free, open-source desktop programs** such as digiKam: powerful, with face recognition and a huge range of settings. Expect to spend time learning it.
- **Self-hosted servers** such as Immich and PhotoPrism: a web app and phone backup you run at home. Excellent if you're happy maintaining a server.
- **Commercial desktop apps with local AI**, such as Excire Foto and firelet.media Gallery: install and go, AI search on your PC. Compare their current features and prices on their own sites — they change.
- **Sync-first apps** such as Mylio Photos: built around keeping a library in step across your devices.

## Where firelet.media Gallery fits

It's a Windows desktop app that indexes the folders you already have, searches by description and by the text in your photos, groups faces, finds near-duplicates and ranks bursts — all on your PC, with no account inside the app. It's $160 once, updates optional. It doesn't decode camera RAW files yet (RAW+JPEG pairs are kept together), and Mac and Linux builds are still being finished.

The fairest test is your own library: [try it free for 14 days](https://firelet.media/download/), every feature, no limits — and switch the Wi-Fi off while you do.

## Questions

### How can I tell whether a photo app's AI runs offline?

Switch the internet off after the first set-up and search again. If search, faces and tags still work, the model runs on your computer. Then read the app's own list of what it sends.

### Does offline AI search need a powerful PC?

No. firelet.media Gallery uses the graphics card through DirectML when it can and falls back to the processor; results are the same either way, only the first indexing is faster on a GPU.

### Which offline organizer is best?

It depends on what you value: a free open-source program with many settings, a self-hosted server you reach from anywhere, or a desktop app that just works. The checklist in this article helps you decide.
