San Francisco is full of places worth stopping for, and most of the time you walk straight past them. A paid tour locks you to a route and a start time, and a guidebook makes you look at a page instead of the street. Rivera is a voice guide that already knows where you are and which way you are facing. You say what you feel like — history, a view, coffee, somewhere to eat — and about every 100 meters it asks Google Places what is nearby, then a live voice agent (ElevenLabs or OpenAI Realtime) tells you one true thing worth a look, such as a Gold Rush block on your left or oysters just ahead. You can change your mind out loud and it switches what it looks for. The hard part was knowing when to stay quiet: city GPS jumps, phones only report a heading while you are moving, and a voice model will fill every pause unless you tell it that a walk is mostly silence. We drop bad fixes, speak only after a real move, and let it use only the places in the latest lookup, so it never invents a landmark you are not standing in front of.
