Mappit.ai — frontier geo-intelligence. 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. And Mappit is frontier geo-intelligence: eight Layer Apps put the official numbers beside the news, coloring the world's countries and America's states, counties and congressional districts by the economy, population, energy, health, conflict and the 2026 US elections, drawing every nuclear reactor and data center, playing it all back through time, and writing an AI analysis of any view on request. 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

Porto Velho sits on the banks of the Madeira River in Brazil's northwestern Amazon basin, capital of Rondônia state. The city sprawls across terrain that transitions from dense rainforest to increasingly cleared agricultural land—a geographical position that makes it both a gateway to the Amazon and, increasingly, a flashpoint in the region's resource conflicts. The Madeira River itself is a major tributary of the Amazon, and Porto Velho serves as its natural transportation hub, though modern highways have gradually shifted the city's role.

History

Founded in 1907 as a support town for the Madeira-Mamoré Railway (a rubber-boom-era infrastructure project), Porto Velho's identity has always been tied to extraction and frontier expansion. The railroad itself is now largely defunct, but its ghost lingers in the city's name and layout. What began as a rubber boomtown evolved through cycles of cattle ranching, timber operations, and more recently, large-scale agriculture—each wave reshaping the landscape and demographics around it.

People & Demographics

Porto Velho is home to roughly 540,000 people, making it a significant regional city by Amazonian standards. The population reflects successive waves of migration: indigenous Amazonian groups (now a small minority), rubber tappers and laborers from across Brazil, ranchers, farmers, and in recent decades, agricultural workers drawn by expanding soybean and cattle industries. It's a frontier city in character—economically ambitious, demographically young, and socially dynamic.

Economy & Markets

Agriculture dominates: soy cultivation, cattle ranching, and timber extraction drive regional commerce. Porto Velho functions as a trade and logistics center—goods move upriver and downriver, and highways connect the region to southern Brazil's markets. The city also serves as an administrative and services hub for Rondônia state. Tourism around the Madeira River and Amazon access exists but remains modest.

Culture & Character

Porto Velho has the texture of a working frontier city rather than a polished destination. River culture runs deep, reflected in local cuisine and transport traditions. The city maintains a rough-edged dynamism—entrepreneurial, sometimes chaotic, shaped by its position as a place people come to do something rather than simply be somewhere.

Current Currents

Porto Velho finds itself at the center of escalating tensions between agricultural expansion and environmental preservation. Recent wildfire outbreaks and documented illegal deforestation in surrounding rainforest sectors underscore a recurring pattern: economic pressure from agribusiness colliding with climate and conservation imperatives. The city itself doesn't generate these conflicts, but it's where they concentrate—in trade flows, in migration patterns, in the visible edge of the Amazon's retreat.
