Escala is a travel companion on WhatsApp for the whole trip, and only for the trip. It is built for the moment travel gets hard: a first trip, a family whose bags did not arrive, a connection in a language nobody in the group speaks. You send your plans once, any way you have them (a confirmation email, a screenshot, a voice note, or just flight numbers), and Escala keeps track of everything. It warns you before a delay shows on the departure board by following the inbound aircraft up to three flights back. Before landing, it prepares what you will need at immigration in the officer's language, from official pages with the date they were read. It answers anything about the trip in English, Spanish or French, and learns how you like to travel only if you say yes. When something goes wrong, it tells you what you are owed. A rules engine, not the model, decides which passenger rights apply (US, Canada, Mexico, EU, UK and the Montreal Convention), and a deterministic verifier blocks any amount, percentage or deadline that neither the rules nor a cited source produced. A photo of a damaged bag becomes dated evidence and a claim letter in minutes. Memory has provenance: Escala tells you what it knows about you, when you told it, and forgets on request. How we tested it: 238 automated tests and thirty end-to-end scenarios with the real models in three languages, including prompt injection by text, voice and location, invented figures, and two volume runs (13 people on the demo at once, and 8 at once with the Meta API forced down, answered by the open-weight fallback). What was built during the event: all of the code in the repository (first commit Oct 26). What existed before: the research and the product design. During the hackathon flights are simulated and declared as such; no live flight data provider is connected, and the demo runs on a real route (Mexico City - Chicago - Montreal) with a fictitious airline. Escala gives information with sources, not legal advice. Kokorio's founder, Ives Laurent, spent four years running airport projects at an airline. Escala is what he wished passengers had.
