# Everything Kokai does, feature by feature

> Kokai is an app to plan trips and take along on them. Before you leave, you save places on a map, build each day’s plan, compare places to stay and store tickets and passport; during the trip, On the road mode alerts you when you pass near something you don’t want to miss. Everything important lives on your device and works offline.

## In a nutshell

- **What it is:** An app to plan a trip (map, plan, accommodation, documents, packing list) and take along on it (proximity alerts and a recorded route).
- **Where you use it:** Today, in the browser, with nothing to install. iPhone and Android, on the way to the App Store and Google Play; Mac and Windows, later.
- **Price:** Free, today. AI is optional and works with your own Anthropic or OpenAI key: that provider charges for each question at its own rates.
- **Your data:** Trips live on your device, with a copy in your account that you can turn off. Your location, your route and your document files never reach our server.
- **Offline:** Trips, plan, documents with their files, packing list, alerts and route. The background map, searching for places and AI need a connection.
- **Advertising:** None. No ads and no advertising cookies.
- **App language:** Spanish. This website is in Spanish, English and Catalan.

- [Your trip map: save places by category, with photos and links](https://kokai.app/en/mapa/): How to save places on the Kokai travel map: search or tap the map, seven categories, priorities, filters, Wikimedia photos and the destination located for you.
- [Your day-by-day trip itinerary: times, transfers and travel between stops](https://kokai.app/en/plan/): How each day’s plan comes together in Kokai: timed places, notes and transfers, how long from one stop to the next and how to ask the AI for a draft itinerary.
- [AI travel planner: mark an area on the map and get specific places](https://kokai.app/en/ia/): How Kokai uses Anthropic or OpenAI with your own key: areas from 100 m to 500 km, suggested places you accept, web search and what data is sent.
- [Offline travel documents: tickets, bookings and passport on your phone](https://kokai.app/en/documentos/): How Kokai keeps tickets, bookings and passport as PDF or photo to open offline, what it warns you about before they expire and what stays on your device.
- [Where you sleep each night: bookings, options and gaps in your accommodation](https://kokai.app/en/alojamiento/): How Kokai organises accommodation by night: bookings, undecided options, gaps, double bookings, free cancellation alerts and the hotel address offline.
- [Proximity alerts near your saved places: how On the road mode works](https://kokai.app/en/en-ruta/): How Kokai alerts you near a saved place: the radii it uses, how it avoids false GPS alerts, what it records of your route and what it does with your location.
- [Where your travel data lives: on your device, in your account and nowhere else](https://kokai.app/en/tus-datos/): What Kokai keeps on your device, what goes to your account copy, which services get anything and when, what never leaves, and how to export or delete it all.

## Before the trip and during the trip

Kokai has two halves that live together in every trip. **Before** is what you do calmly, ideally on a big screen: the [map](https://kokai.app/en/mapa/) with your places, each day’s [plan](https://kokai.app/en/plan/), each night’s [accommodation](https://kokai.app/en/alojamiento/), the [documents](https://kokai.app/en/documentos/), the packing list and the [AI-powered interests](https://kokai.app/en/ia/). **During** is what you do with your phone in your pocket: [On the road](https://kokai.app/en/en-ruta/) mode, which alerts you when you pass near your places, records your route and reminds you where you’re sleeping tonight.

If it’s your first trip with Kokai, the [five-day Lisbon and Sintra guide](https://kokai.app/en/planificar-un-viaje/) walks through it from start to finish with an example.

## What works offline

You look at a trip on a plane, in a country where you have no data or in the boarding queue. That’s why the important things are on the device and don’t depend on the network:

| What | Offline | Why |
| --- | --- | --- |
| Trips, places, plan and packing list | Yes | They’re saved on the device; the account copy catches up when the connection comes back. |
| Documents and their files | Yes | The PDF or photo is saved on the device and opens without a connection. |
| Reading a booking PDF | Yes | It’s read on the device, with no AI and no server. |
| Proximity alerts and route | Yes | GPS doesn’t use the internet, and distances are worked out on the phone. |
| Reminders (flight tomorrow, passport…) | Yes | The device schedules them itself. |
| Signing in to the app | Yes, after the first time | Only the first sign-in on each device needs a connection. |
| The background map | Not yet | Map tiles are requested as you view them. Offline maps by area are on the way. |
| Searching for places and locating the destination | No | OpenStreetMap search services are queried. |
| Photos and links for places | No | They’re looked up on Wikipedia, Wikidata and Commons. |
| Interests, plan and notes with AI | No | Questions go to the provider you choose. |

## What’s done and what’s missing

This website describes what the app does today. What’s built but can’t be used yet is labelled “Soon”, and what doesn’t exist yet is described as pending:

| Feature | Status |
| --- | --- |
| Map, plan, accommodation, documents, packing list, AI-powered interests, On the road | Available now, in the browser. |
| Copy of your trips in your account, across devices | Available now. |
| Sign in with Google | Done; the project still needs to be verified by Google. |
| Documents in Google Drive and trip in Google Calendar | Soon. |
| iPhone and Android app, with alerts while the screen is off | Soon: on the way to the stores. |
| Mac and Windows app | Later. |
| Offline maps by area, real routes | Pending. |
| Sharing a trip with the people you travel with | Pending: it’s next. |
| Trip expenses with splitting | Pending. |

## How these pages are made

Each feature page explains one part of the app with its real figures (radii, times, limits), taken from the code, and ends with the steps to check it yourself in the app, frequently asked questions and links to the original documentation of what it cites. Each one says when it was last reviewed.

All of them also have a Markdown version (the one for [On the road](https://kokai.app/en/en-ruta/), for example, is at `/en-ruta.md`), and there’s an index for AI assistants at `/llms.txt`, with the full text at `/llms-full.txt`.

## Frequently asked questions

### Do I need to create an account?

Yes, to save your trips and have them on your other devices. You create it with your email, and only the first sign-in on each device needs a connection.

### Do I have to use AI?

No. Everything works without AI: the map, the plan, the documents, the alerts. AI is an optional helper to discover places and suggest a plan, and it only switches on if you add your key.

### How is it different from a map with saved places?

The map is just the beginning: places are arranged into days with estimated transfers, each night has its accommodation, your tickets are right there and, during the trip, the app alerts you when you pass near them.
