# Rochat on Web, iOS and Android

Choose Rochat Web, iOS or Android and understand why a feature or control can look different on another device.

Read this guide in: [English](https://book.rochat.ai/rochat_book_en/platforms) · [繁體中文](https://book.rochat.ai/rochat_book_zh/platforms) · [日本語](https://book.rochat.ai/rochat_book_ja/platforms) · [Español](https://book.rochat.ai/rochat_book_es/platforms) · [한국어](https://book.rochat.ai/rochat_book_kor/platforms)

Rochat is available through the Web and mobile apps. Use the official download page to find the correct app for your device, and keep the app updated before following a new tutorial.

## Which platform should I use?

| Task                                            | Where to start                                                               |
| ----------------------------------------------- | ---------------------------------------------------------------------------- |
| Browse characters and start a chat              | Web or the Rochat mobile app.                                                |
| Work on detailed character or Scene text        | A desktop browser gives you room to edit and compare fields.                 |
| Open the World creator                          | Sign in on desktop Web and choose **Create → World**.                        |
| Follow an app-specific experience or control    | Open the current Rochat app and use the controls available for that version. |
| Manage an App Store or Google Play subscription | The store account used to buy it.                                            |

The Web creation menu includes separate entries for World, Character, Scene and Group Scene. Mobile Web has a different layout and may not expose the same creation entry points as desktop Web.

## Move between devices carefully

1. Note the sign-in provider used on the first device.
2. Sign in with that same provider and account on the second device.
3. Compare the account identifier before assuming missing content is a sync problem.
4. Open the same character, conversation or work. A new conversation can have different context and Memory from an existing one.
5. If an item is missing, collect the item link and account identifier for support. Do not create a second account to try to recover a purchase.

## When a tutorial does not match your screen

Check the app version, platform, account entitlement and whether you own the work being edited. A screenshot from Web is not a promise that the same button exists at the same location on iOS or Android.

Update from the official store, reopen the app, and check again. If the control is still absent, use [Get official Rochat support](https://book.rochat.ai/rochat_book_en/about-rochat/faq) and include the platform, version and a screenshot with private content hidden. See [Manage subscriptions and refunds](https://book.rochat.ai/rochat_book_en/about-rochat/faq/subscription-faq) for purchases and [Start with Rochat World](https://book.rochat.ai/rochat_book_en/rochat-world) for World-specific entry conditions.
