Product case study

TripInt

Planning a trip across Europe can mean checking routes, prices, stays, and visa rules in several places. TripInt brings the information into one clear plan, so Indian passport holders can understand the trip before they spend.

The problem

Planning a Schengen trip can require spending before the visa is certain.

A traveller needs dates, a route, flights, stays, travel between cities, and a budget before applying for a visa. Flight and hotel prices keep changing. The cheaper options can also have strict change rules or no refund.

The information is spread across booking sites and consular pages. Travellers still need to work out the total cost, the country they must apply to, the money they need to show, and the documents they need. TripInt puts those answers into one plan before they book or choose their visa dates.

The product

One planning flow, built from the traveller's details.

Describe the trip

The traveller adds a departure city in India, month, trip length, budget, number of adults, route, nights, type of stay, and travel preferences.

Add the visa details

The next step collects only the personal and financial details that can change the visa plan, warnings, or documents.

Review the complete plan

TripInt then combines the route, full planning range, available budget, flight options, travel between European cities, actions, and documents.

Product decisions

Four decisions shape how TripInt works.

Complete cost

No partial trip totals.

TripInt opens the result only when every required range is available. The total can include return flights, paid stays, European transfers, visa fees, service fees, insurance, and fixed costs.

Route logic

The route controls the rest of the plan.

The order of cities controls the arrival, departure, travel between cities, hotel nights, and the country responsible for the visa application. The main purpose of the trip and the longest stay determine which country's visa plan applies.

Source clarity

Every price shows its source and when it was checked.

Prices show where they came from and when they were checked. A saved price is used only when it still matches the route, dates, travellers, rooms, and type of stay.

Clear promise

Preparation, not visa approval.

TripInt helps a traveller prepare a practical route, budget, and document list. Official consular sources remain the final guide, and only a consulate can decide the visa result.

Live scope

Six countries, up to six cities, and rules that change with the trip.

6destination countries
6cities in one route

TripInt supports France, Germany, Italy, Spain, the Netherlands, and Switzerland. A trip can last from 2 to 90 days and include one to nine adults.

Routes with more than one city can compare trains and flights within Europe. Hosted stays, overnight journeys, the documents required by each country, previous refusals, and funding choices all change the plan.

Testing

The core rules were tested before launch.

5,000 routes

The tests covered city order, nights, transfers, duplicate cities, day visits, and overnight journeys across 5,000 routes.

1,440 journeys

The tests covered purpose, accommodation, work, funding, refusal, documents, fees, and visa country decisions across 1,440 journeys.

Mobile and desktop

Browser checks covered 360 px, 390 px, and 1280 px screens, including long names, errors, touch targets, and horizontal overflow.

Built with AI

TripInt was built end to end with Codex.

AI was part of every build cycle, from planning the product to testing the live experience.

Future scope

More of Europe first, then destinations beyond it.

Where TripInt can go

TripInt currently covers six European countries. The next scope can cover the rest of Europe before expanding to countries outside Europe. Each addition will need its own visa rules, fees, document checks, and travel costs.

Planning, not booking

TripInt will continue to show planning ranges, not booking quotes. Travellers will still need to confirm the final visa requirements with the relevant consulate.
