Multilingual visitor guide
Hypothetical. Not a client, not a result.
// The problem
A heritage site prints its visitor guide in two languages, tours in other languages need a guide on staff, and the front desk answers the same questions about hours, access and parking all day.
// What we would build
A visitor guide in a phone's browser, opened from a code at each stop, in the languages your visitors speak, with an assistant that answers from your own texts, names its source and hands anything it cannot answer to staff. Your interpretation team writes and approves every text.
// What is in it
- Stops opened from a code on the wall, with text, images and audio
- The guide in the languages you choose, approved by your team
- An assistant that answers from your own texts and names its source
- Hours, access, parking and accessibility answered the same way every time
- Questions it cannot answer handed to the front desk
- A set of real visitor questions, run before every change
