Breathe life into your family history. Transform black-and-white photos into vivid color with historically accurate tones—not generic AI colorization, but era-appropriate colors informed by decades of historical research.

Upload a photo of your grandparents' wedding, your great-uncle in uniform, or that faded vacation snapshot. The agent analyzes visual cues—clothing styles, hairstyles, architecture, vehicles—to identify the era, then applies period-accurate colors: the precise olive drab of a WWII Army uniform, the pastel palette of 1950s fashion, the earth tones of the 1970s.

Every colorization explains its choices. "The military uniform appears to be US Army WWII, so I've applied olive drab (OD #3). The woman's dress style suggests mid-1940s, typically in muted navy or forest green." You stay in control—adjust any color that doesn't match your family's stories.


**Limitations:** Requires a clear enough image to identify era cues. Cannot repair physical damage like scratches or tears. Complex scenes with many period-specific elements may need iterative refinement.
