Sources and licences
Our guides are built on open, verifiable sources. This page lists where the data comes from, under which licence we use it, and how the texts and audio are made.
Map data – OpenStreetMap
© OpenStreetMap contributors. The data is available under the Open Database License (ODbL 1.0): openstreetmap.org/copyright. Map display: © Mapbox.
Facts – Wikidata
Basic data about places (name, type, year built, heritage status) comes from Wikidata, which is available under CC0 as public domain.
Articles – Wikipedia
We extract facts from Wikipedia articles; we do not copy their text. The articles are available under the Creative Commons Attribution-ShareAlike 4.0 licence (CC BY-SA 4.0). Every stop lists the articles we used.
Photos – Wikimedia Commons
Photos come from Wikimedia Commons, each under its own licence (CC0, CC BY, CC BY-SA or public domain). Every photo shows its author, licence and a link to the original file.
How the texts and audio are made
From the facts collected and checked from open sources, we write and translate the texts of the stops with the help of artificial intelligence (Anthropic's Claude language model). The narration is read by a synthetic voice (ElevenLabs).
The texts pass automatic checks (every fact tied to a source, language checks) and are then reviewed by our editors. If the review is not finished by the promised deadline, the guide becomes available and the review is completed afterwards. If you find a mistake, report it at the stop – we look at every report.
Fonts and software
Fonts: Archivo and IBM Plex Mono, SIL Open Font License 1.1. The open-source software used in the app and its licences are listed in the app under Profile → Sources and licences.
