# Usage and limits

> How the Cartographer usage allowance works, where to check your remaining capacity, and what happens when you reach your limit.

## How usage is measured

Cartographer draws on an AI model to reason about your requests. Each session consumes capacity from a usage allowance set for your account.

## Where your usage allowance comes from

Cartographer requires a user license. Each license tier includes an [AI and Agentic usage pool](https://docs.uipath.com/automation-cloud/automation-cloud/latest/admin-guide/ai-and-agentic-usage-pool), a monthly allowance shared across UiPath AI and Agentic products, including Autopilot, Agent Development, ScreenPlay Development, Conversational Agents, and Autopilot for Everyone.

The allowance is per user and monthly: it resets at the beginning of each month, and unused allowance does not carry over.

## Checking your usage

Cartographer tells you directly, in the conversation, when you are close to your limit. You can also check it anytime under [Settings → General](general-settings.md#general), which shows a monthly usage card with the percentage used and remaining.

## What happens when you reach your limit

Cartographer notifies you as you approach your allowance limit. If your administrator has granted a top-up, they continue drawing from it once the monthly allowance is spent. Once both the monthly allowance and any top-up are spent, they pause until a top-up is granted or the monthly allowance resets.
