Strata: History Beneath You

The ground you are standing on has 2,000 years stacked under it. Most of it is invisible. Strata digs it up.

Press one button and Strata reads your exact position, searches open historical archives, ancient gazetteers, and the geologic record around you, then writes the story of your spot - battles, temples, castles, iron furnaces, famous lives, and the rock beneath your shoes - as one readable, cited narrative.

WHAT YOU GET • One story, three rings: right where you stand, within a short walk, and the land around you — each told from deepest past to present • Six eras, color-coded everywhere: deep time, prehistoric, ancient, medieval, early modern, modern • Every fact cited. Sources are listed with their distance from you, one tap from the original record • A map of everything you've discovered, pinned and filterable by era • Photographs of the sites around you as you read • A journal of every spot you've ever dug - yours to revisit offline, forever

Your first dig of any spot takes a moment while the story is written; after that it's instant, for you and for everyone who ever stands there after you.

HONEST BY DESIGN Narratives are AI-synthesized exclusively from cited open sources (Wikipedia and Wikidata contributors CC BY-SA, Macrostrat geology). Passages of general era background are clearly marked "period context" - Strata never invents records of your exact spot.

PRIVACY Your location is used while the app is open - that's the whole product. Your exact position stays on your phone; digs are shared by neighborhood-sized square, never by your footprints.

Stand somewhere old. Ask what happened here.
