Mappit — every place has a story

The world's zeitgeist on a map. Mappit turns the world's news into a living, interactive map. An always-on news engine continuously reads what is happening in nearly two thousand places — its own crawler, which reads the world's publishers directly and supplies more than nine in ten new stories, working alongside frontier AI from Google, OpenAI, Anthropic and xAI in the jobs a crawler cannot do — and pins each story to the place it is about, on an interactive, time-aware map of the planet. Zoom into any city and you see what's happening there right now — grouped by topic, colored by mood, drawn only from publishers that clear a reliability bar and weighted toward the most trusted, marked with how many independent sources found it, and with every source link checked so the stories you read actually lead somewhere real. Scrub the calendar backwards and the map replays how the world looked on any past day, because each day's record is kept rather than replaced.

On top of that news layer, Mappit adds live views of the physical planet — earthquakes, wildfires, air quality, and weather — and a market layer that plots stock movements at companies' real headquarters. A built-in AI guide named Marco answers questions about any place and cites its sources — the news there and, from an atlas of open data, its population, borders and statistics, each figure with its year and source. Anyone can browse for free; a subscription unlocks the ability to create and share your own places, collections, and data layers. And AI assistants can read Mappit directly: add https://mappit.ai/mcp to Claude, ChatGPT or another assistant, free and without an account.

The core idea is simple and durable: place + time is the most natural way to organize what is happening in the world, and the value compounds every day as the record grows. The map is the interface; the permanent, corroborated, geolocated corpus of world events beneath it is the substance.

Mappit requires JavaScript for the interactive map. Every public place, pin, collection and profile also has a crawlable page — see the sitemap.

Mappit's analysis

Geography & Setting

Keystone is a small town in Pennington County, in the heart of the Black Hills. It sits in a narrow, pine-covered valley along Battle Creek at roughly 4,300 feet, with granite ridges on every side. Rapid City is about 25 miles northeast, and the town is best known for being the nearest community to Mount Rushmore, a few miles up the road. U.S. Highway 16A runs through the main street, and Highway 244 climbs from town to the memorial. The scenic Iron Mountain Road (16A) heads south toward Custer State Park, with its pigtail bridges and tunnels framing views of the presidents.

History

The Black Hills are the heart of Lakota country, guaranteed to the Sioux in the 1868 Treaty of Fort Laramie. After gold was found, prospectors poured in anyway, and the U.S. seized the Hills in 1877. A 1980 Supreme Court ruling held that the taking was unlawful and awarded compensation, which the Lakota nations have refused to accept, insisting on return of the land.

Keystone grew out of that rush. It takes its name from the Keystone Mine, and gold, along with other minerals, drew early settlers. The surrounding pegmatites are known for mica, feldspar, and large crystals of minerals like spodumene. Mining faded over time, but the town's fortunes shifted again when sculptor Gutzon Borglum began carving Mount Rushmore in 1927. Workers and then visitors came through Keystone. Carrie Ingalls, sister of Laura Ingalls Wilder, lived here for years, and local history often mentions her.

People & Demographics

Keystone is tiny, with a permanent population in the low hundreds. The summer population of workers, seasonal residents, and visitors is much larger. Many residents have ties to tourism, local services, or nearby Black Hills communities.

Economy & Markets

Tourism is the economy. Main Street is lined with motels, restaurants, gift shops, fudge and ice cream counters, and family attractions. Visitors can tour the Big Thunder Gold Mine, explore Rushmore Cave, or browse the Keystone Historical Museum. Business is strongly seasonal, peaking from late May through September, especially around the Sturgis Motorcycle Rally in early August, when bikers fill the Hills' roads. Winters are quiet, and some businesses close.

Culture & Character

Keystone feels like a classic American roadside town: part mining camp, part tourist strip, with a frontier look that is partly authentic and partly staged for visitors. What makes it distinctive is its setting. Granite spires and ponderosa forest surround it, and Mount Rushmore and the in-progress Crazy Horse Memorial (about 17 miles away) lie nearby. The town's cultural backdrop also includes the Lakota perspective, in which the Black Hills (Paha Sapa) are sacred and the Rushmore mountain is remembered as Six Grandfathers. Many visitors engage with that history, and Indigenous voices are increasingly part of regional interpretation.

For a map nerd, Keystone is a good example of how one landmark can define a whole valley economy. It's a place where geology, treaty history, and roadside Americana all overlap on a single main street.
