CityChat

A city guide you talk to. Ask what's worth seeing tonight, point your camera at a building and get its story, wander with a map that knows the neighborhood.

Guidebooks don't answer questions. Cities should.

CityChat is a native mobile app for exploring a city through conversation. Instead of scrolling lists and reviews, you ask — and an AI guide grounded in a carefully curated local dataset answers, with places it can actually stand behind.

See a building you can't name? Point the camera at it and CityChat figures out what you're looking at and tells you the story. Everything is built on open data — no scraping walled gardens — and the dataset is curated city by city.

Chat

Conversational discovery — food, culture, history, plans for tonight.

Camera

Frame a landmark and get its story — or point at a menu or sign and read it in your language.

Discover & Map

Curated picks by mood and category, on a map built for wandering.

Live. iOS & Android.

CityChat launched in August 2026 and now runs in 15 cities across Poland and Spain — over 35,000 curated places. The full stack is mine: native apps on both platforms, a Go backend with geospatial and vector search, LLM-powered chat, and the data tooling that keeps the city knowledge fresh. The app finds your city by location, local businesses manage their listings through a self-serve portal, and PRO subscribers can download whole cities for offline use. It keeps launching city by city — and started close to home.

Get it on the App Store or Google Play — one smart link routes you to the right store: citychat.pl/app. The full story, cities, and business offer live at citychat.pl.
