Felicity

The offline face-recognition photo organizer for Windows. It finds and groups every photo of the same person across your whole library, automatically. Free for personal and commercial use.

• All on your machine: Google Photos can do this, but no one wants to upload terabytes of memories to the cloud. Felicity does the same grouping locally, on your own PC.
• ~99.9% accuracy - real world test: Not a lab benchmark. Tested across 116,779 of my own photos: weddings, travel, family, and the random clicks around the house.
• Fast, and barely needs you: It sets the accuracy straight on its own. Any tag you add just adds weight for recalibration, and recalibrating never triggers a rescan.
• Built for everyone by professional: A mountain of family photos but you're not a software engineer? You don't need to be one anymore. It just works.
• Clutter-free, not stripped down: Power tools are there when you want them, tucked away when you don't: export XMP for professional apps, view metadata, and export grouped photos.
• Private, Always: It never touches the network (mapped drives aside, which is on you) and never modifies your originals. Your library stays exactly as it is.
• Functional and beautiful: Accessibility built in: high contrast, dyslexia-friendly fonts, and colour-vision support, so anyone can use it with ease.
• Free, no strings: No ads, no limits. You're free to modify the source or decompile the installer under the EULA. Only redistribution is restricted.
• Light on your system: It throttles itself in the background and allocates resources dynamically, so a big scan never bogs down the rest of your machine.
