122 cities. Every continent.

Things to do in
every city on earth.

Straight answers, curated lists, and in-depth guides:
backed by live local data. No ads, no sponsored rankings, no fluff.

TTDI is an answer engine for travel. Every page answers one specific question: when to visit, what a day costs, where locals eat, whether it's safe: in the first fifty words, and then earns that answer with the climate record, the current exchange rate, and a catalog of places we can stand behind. No stubs, no sponsored rankings, no filler. A page exists because travelers keep asking its question, and for no other reason.
