Build credits and Cloud credits are billed and topped up separately, so it helps to know which one a charge belongs to:
  • Build credits pay for building your app inside Rork.
  • Cloud credits pay for the AI and cloud features your app uses while it runs, including for your own users once the app is live.

At a glance

​
Where to find them

1

Click your avatar

It is in the top-right corner of Rork.
2

Read both balances

Credits is your build credit balance. Cloud Credits is your dollar balance.
3

Open Billing

Click Billing in the same menu. The tabs on the left are Build Credits, Cloud Credits, Payments, and Purchases.
The same menu has shortcuts to upgrade your subscription, buy Cloud Credits, and open Billing.

​
Build credits

Build credits are spent while you create and edit your app in Rork. They cover:
  • AI chat messages with the agent.
  • Builds and previews started from the editor.
  • Asset generation while building (images, audio, 3D, and similar).
  • Publishing and platform work.
They are tied to your plan and subscription, so how many you get and how usage is counted depends on your plan. This is the balance that drops as you keep prompting and building. See Subscriptions to compare plans. The Build Credits tab in billing shows your remaining balance, subscription versus usage credits, and your current plan. On Max plans you can also top up credits as you go:

​
Cloud credits (Rork AI Cloud)

Cloud credits are a separate balance that your finished app spends at runtime through Rork AI Cloud. They are not part of your plan: you enable Rork AI Cloud for a project, and Rork gives you a one-time $1 in Cloud credits for free so you can try adding AI to your app and run a few tests. The balance is shown in USD, and it drops only when your app actually uses a cloud feature. Cloud features that draw from this balance include:
  • Backend functions.
  • AI features like chat, images, and voice.
  • Web search.
  • Media and 3D generation.
The Cloud Credits tab in billing shows the USD balance and an Add funds section. It also has a toggle to use Rork Cloud and a summary of recent cloud usage by your app:

Before relying on AI features, make sure Use Cloud Credits is turned on for the project, like in the panel above. If it is off, the app stays on legacy features only and will not use Rork AI Cloud.

​
Add funds

1

Open Billing, then Cloud Credits

Use the avatar menu, or click Buy Cloud Credits in the same menu.
2

Check that Use Cloud Credits is on

The toggle sits at the top of the tab.
3

Pick an amount

Choose a preset or type your own. You can add from $5 to $200 at a time.
4

Click Add

The balance updates a moment after the payment goes through.

​
Keep your app running

So your app’s cloud features do not stop mid-use, set up one or more of these:
  • Low-balance email. Rork emails you when the balance drops below a level you choose. The default is $5. Set it to $0 to turn the email off.
  • Auto top-up. Rork charges your saved card and adds funds when the balance drops below that same level. You choose how much to add each time, from $5 to $200.
  • Monthly spending limit. After your first paid top-up, the Cloud Credits tab shows this limit. Automatic top-ups stop before they go over it.
Rork may also show a project notification when Cloud credits are running low or run out, with a quick link to add credits.
1

Add funds once

Auto top-up needs a saved card. Rork saves your card with your first paid top-up.
2

Open Billing, then Payments

Find Auto top-up cloud credits.
3

Turn it on and set the amounts

Set When the balance drops below and Top up by.
4

Click Save auto top-up

Rork confirms that the settings are saved.

​
What you can build with AI features

Every example below runs through Rork AI Cloud, so it uses Cloud credits when people use your app. Describe the feature in chat. You can name a model, or let the agent choose one.

AI chat assistant

“Build a fitness coach app. Users chat with an AI coach about their week and get a simple plan.”

Photo and image apps

“Build an app where users upload a selfie and get four graduation photos.” Follow the full tutorial.

Voice apps

“Build a language tutor. The user speaks, and the app answers out loud.”

Research with web search

“Build a trip planner that checks the web for current opening hours and prices.”

Video and 3D

“Build an app that turns a product photo into a short video clip.”
The more your users use these features, the more Cloud credits your app spends. The price table at the end of this page shows what each model costs.

​
Free on-device AI on iPhone

Some AI features do not need Cloud credits at all. On iPhone, Apple’s Foundation Models framework lets a Swift app talk to Apple’s own language model, which runs on the phone. Apple describes this AI inference as free of cost. This means:
  • It is free for you. No Cloud credits and no per-request charge.
  • It is free for your users. They do not pay for each request.
  • It works offline and keeps the user’s data on the device.
iOS 27 makes this better. Apple rebuilt the on-device model for iOS 27: it is better at logic and tool calling, and it can read images that you put in the prompt. See What’s new in the Foundation Models framework from WWDC26.
Building the app still uses build credits. Only the AI requests that run on the phone are free.

​
What to expect

  • It needs a supported iPhone. The user needs an Apple Intelligence-compatible iPhone (iPhone 15 Pro or newer) with Apple Intelligence turned on. Your app still installs on other iPhones, but the AI feature will not be available there.
  • The model is small. It is good at short tasks: sorting, pulling out names and dates, short summaries, rewriting short text, and filling in forms. For complex reasoning, long writing, or realistic images, use Rork AI Cloud.
  • Rork adds it to Swift iPhone apps. It is not available in web apps or React Native apps. See Swift vs React Native to pick the right type.
A good setup for many apps: use the on-device model when the phone supports it, and fall back to Rork AI Cloud when it does not. You can ask for this in chat:
Add a feature that sorts a pasted receipt into categories. Use the on-device Apple model when the iPhone supports it. Otherwise use Rork AI Cloud.

​
If a charge looks wrong

First check whether it was build activity (inside the editor) or cloud usage (your running app). On-device AI never creates a charge. Then collect the project link, the approximate time, and the action, and contact support so the usage can be reviewed.

​
Available AI models

These are the AI models you can use in your app. You don’t have to pick one up front: just tell Rork what you want to build. You can name a specific model, or let the agent choose the best one for the task. Prices are per 1 million tokens. Image, video, audio, and embedding models are billed differently, so their token prices show as a dash.
