Live local time and weather. The time in each city comes from your browser's clock and that city's time zone. If you are online, current weather comes from Open-Meteo.com (free, no key) and tints the sky and adds rain or snow; offline, or with the "Designed" toggle, you get the hand-designed look.
Voice is the browser's own. The mic button and the spoken answers use your browser's built-in speech features (speech recognition and speech synthesis). This site never records or stores audio; where your browser sends speech for recognition is up to the browser.
Your own city. If you type where you are, one lookup goes to a free geocoder (Photon, or OpenStreetMap's Nominatim as a fallback) and one to OpenStreetMap's Overpass, straight from your browser, to draw your streets. If either is slow or blocked you get a designed street instead.
No paid services. No APIs, no tracking, no paid assets. Sound is synthesised live with WebAudio. It's a static site on free hosting.
