# How do credits work and what happens if you run out?

### Understanding message credits

Each interaction between a user and a twise instance requires a message credit. Depending on the voice model being used, some interactions may require two message credits per message. Each twise plan includes a set number of message credits, which are shared across all the twise instances under that plan. This means that a single plan's credits are distributed among all its twise instances.

### Managing message credits

**Alerts for low message credits**

When your message credits are running low, the admin of the account will receive an email alert. Additionally, there will be a notification in the admin dashboard indicating that you are about to run out of credits.

**Adding more message credits**

At present, adding additional message credits is a manual process. There is no auto-billing or automatic upgrade option available. To add more credits, you will need to contact the Twise team (<hello@twise.ai>) who will assist you in replenishing your message credits.

### What happens if you run out of credits?

When a twise runs out of credits, it will still be visible and accessible. However, the input bar where users type or speak their requests will become invisible. This means users can only interact with the twise through any navigation items under the menu or the initial three suggested responses on the welcome page.

Additionally, as an admin, you will not be able to update the content or make any changes to any of your twises if the account has no more credits.

For any further assistance or to add more message credits, please reach out to the Twise support team (<hello@twise.ai>).
