A workspace, not an itinerary generator
Itinerary, budget, documents, bookings, readiness, and risks share one trip-scoped model.
Mobile product · AI workspace
Viya
Viya is a mobile travel workspace for itineraries, budgets, documents, bookings, and trip readiness, with AI-assisted changes that travelers review before saving.

Problem and response
The problem
Travel plans are fragmented across messages, booking apps, receipts, maps, notes, and spreadsheets. Most AI travel tools stop after generating an itinerary.
The approach
Each trip has structured records for itinerary, budget, documents, bookings, readiness, and risks. The assistant can draft changes across those records, explain them, and wait for the traveler to approve them.
Architecture
The mobile app, Convex backend, and AI provider layer share TypeScript and Zod contracts. Each layer can be tested or replaced without moving product rules into the interface.
Mobile application
Expo Router and React Native organize authentication, trip workspaces, Vault, budget, and readiness flows.
Shared TypeScript contracts
Pure TypeScript logic and Zod schemas keep the mobile application, backend functions, and generated output aligned.
Convex backend
Queries, mutations, storage, and user-owned trip records sit behind Clerk-backed identity checks.
AI provider boundary
Provider selection, structured generation, trip context, and deterministic fallbacks are kept behind one interface.
Key product and engineering decisions
These decisions affect what users can do, where product rules live, and how the system handles failure or change.
AI proposes; the traveler decides
Generated changes are checked against shared schemas, explained to the traveler, and saved only after approval.
Demo reliability without fake success
Deterministic fixtures and fallbacks keep critical flows testable when a model or provider is unavailable.
What you can inspect
The live product and public repository provide concrete evidence of the implemented features, architecture, tests, and documentation.
- Domain and backend contract tests cover trip modules, budgets, itinerary, readiness, Vault, and AI draft application.
- Shared schemas validate structured AI outputs before application code consumes them.
- Architecture, security, setup, testing, demo, and product decisions are documented in the public repository.
- An Android preview-build path and repeatable demo fixtures are documented for release review.
