# Billing and AI CreditsWebPros Nova uses a monthly subscription model with four paid tiers: Start (15 credits, 1 project), Build (35 credits, 5 projects), Grow (85 credits, 15 projects), and Scale (200 credits, 30 projects). Each completed AI build costs 1 credit. Credits reset monthly with no rollover. The free plan provides 3 credits and 1 project but restricts publishing and Code Editor access. Check usage at Account Menu > Settings > Plan & Usage.

Nova uses a subscription billing model. Paid plans include more credits and let you access more features.

This page explains what plans are available, what a credit is, and how you can monitor and manage your credits.

## Plans

Each plan includes a set number of credits and projects. Projects are the digital experiences that you create with Nova, such as apps and websites.

### Free plan

You can use the free plan to try Nova before you choose a paid plan. The free plan includes 3 credits and 1 active project. This plan restricts some features, including website publishing and code editor access.

### Paid plans
Paid plans include credits and active projects based on your tier:

| Plan | Credits | Active Projects |
| :--- | :--- | :--- |
| Start | 15 | 1 |
| Build | 35 | 5 |
| Grow | 85 | 15 |
| Scale | 200 | 30 |

### Billing

Your provider bills paid plans as a monthly subscription at a flat rate.

If you switch plans mid-cycle, your provider may prorate your charges or adjust your next invoice based on the plan change. Your provider may also change your available credits and active projects immediately.

Contact your provider for more information.

## Credits

Each plan includes credits that you can spend to create digital experiences.

If you run out of credits, Nova will limit your ability to create digital experiences. Depending on your provider, Nova may stop all [AI builds](#ai-builds) until your credits refresh.

### Credit display

You can see how many credits you have remaining in the Account Menu.

The Account Menu also shows when your credits refresh each month.

Your unused credits do **not** roll over to the next month.

### AI builds

When you send a prompt to Nova, Nova starts an AI build.

An AI build includes:

- The prompt you send to Nova.
- Nova's AI reasoning, planning, and code generation.
- The final result of your request. This could be ready-to-publish website or app, or an update to your existing project.

Each completed AI build uses **1 credit**. To learn how to use your credits efficiently, read our [Prompting Best Practices](/en/welcome/prompting-best-practices/) documentation.

If Nova is interrupted and does not complete a full AI build, check your usage history to confirm whether Nova consumed a credit.

You can check your usage history at _Account Menu >> Settings >> Plan & Usage_.
