Show HN: CityVois – AI travel guide that tells stories and spots landmarks

Hi HN,

I created [CityVois](https://www.cityvois.com) as an AI-powered travel assistant for solo travelers and cultural explorers.

It detects your current location and nearby landmarks, and shares cultural and historical stories in both voice and text. It also allows users to recognize landmarks via photos – we currently support over 18,000 globally.

For now, we've curated citywalk routes in cities across China and Japan, designed to help users explore hidden stories around them without relying on traditional guidebooks.

Technically, the app is built with Flutter, uses Firebase for backend services, and combines GPS with image recognition for real-time landmark detection. Would love any feedback, thoughts, or suggestions – especially around UX for solo travelers and improving performance.

Thanks!
