How the trip planner works

From a vague idea to a complete trip — in under a minute.

01

Tell the AI your dream

Where, when, and what you love. Beach mornings? Underground food spots? Roman ruins? The trip planner listens.

02

Get a smart itinerary

A day-by-day plan tuned to your pace, with iconic sights and the kind of places only locals share.

03

Travel — even offline

Download maps, audio guides and content. Your full trip works without data, anywhere in the world.

More than a trip planner

An entire travel guide. In one app.

Most trip planners just build itineraries. Secret World does that — and helps you actually explore the world around you, with content most apps simply don't have.

AI Itineraries

Personalized day-by-day plans built in seconds. Tweak, swap, regenerate.

Hidden Gems

Curated spots beyond the obvious — places guidebooks miss and locals love.

Audio Guides

Walk through cities with stories in your ears. Multilingual, professionally written.

Around You

Pull up your phone anywhere — discover what's worth seeing within walking distance.

Trip Toolkit

Currency converter, travel docs, packing helpers. The little things that make trips smoother.

Works Offline

Download once, explore forever. No data, no roaming charges, no friction.

Other trip planner apps stop at "here's your itinerary." Secret World keeps going — with cultural depth, local stories, and 1.3 million places you'd never find in a generic chatbot.

Trip planner FAQ

Things people ask before downloading.

What is the best free trip planner app?
Secret World is among the most complete free trip planner apps available today. It combines AI-powered itinerary generation with 1.3 million destinations, hidden gems, audio guides and offline maps — all in one free app for iOS and Android. Unlike apps that focus on booking or just simple lists, Secret World is built to be both your trip planner and your travel guide.
Is the trip planner really free?
Yes. Free to download, free to use. The core experience — AI itineraries, 1.3M+ destinations, hidden gems, audio guides — is free forever. Optional premium features unlock advanced planning for power users.
How does the AI trip planner actually work?
Tell the app where you're heading, how many days you have, and what you love (food, history, nature, nightlife). The AI builds a day-by-day plan in seconds. Don't like a stop? Swap it. Want a different vibe? Regenerate. It learns from your preferences as you use it.
Can I use the trip planner offline?
Yes. Download maps, audio guides and itinerary content before you go. Perfect for international trips where data costs add up. Once downloaded, your full trip works anywhere — no signal, no problem.
What makes this trip planner different?
Most trip planners give you an itinerary and stop. Secret World adds a full travel guide — hidden gems, audio guides, cultural articles, “Around You” discovery, food and wine content — in 62 languages, covering 195 countries. It's a planner and a guide in the same app, built by travelers for travelers.
