## What Are Credits

Credits are units consumed when you use AI features. Each time you generate or edit text with AI, credits are used. You only spend what you use.

## How Many Credits You'll Use

| Use case                | Credits (approx.) |
| ----------------------- | ----------------- |
| Short email reply       | \~30              |
| Summarize meeting notes | \~50              |
| Sales proposal          | \~100             |
| Business plan           | \~200             |
| Long-form article       | \~300             |

*Actual credit usage varies based on content length and conversation.*

## Billing Cycles

* Pro is available with monthly or annual billing
* Max is available with monthly billing only
* Annual plans still add and reset credits every month instead of granting a full year of credits at once

## How Credits Work

* Each plan gives you monthly credits that reset every month and do not carry over
* Bonus credits, purchased credits, and plan carryover credits can carry over
* Plan carryover credits have an expiration date
* Check expiration dates in Settings. Credits that expire before your next monthly reset are used first
* Pro and Max plan members can purchase additional credits
* Check your balance in the "Plan" tab in Settings

## Plan Changes

### Upgrade

* Takes effect immediately
* A new billing period starts, and new plan credits apply right away
* When you switch immediately from a paid monthly plan to the same plan billed annually, or to a higher plan billed monthly or annually, unused credits become plan carryover credits
* Changes from an annual plan and changes to a lower plan are not eligible for plan carryover credits

### Downgrade

* Takes effect at the end of your current billing period
* Keep your current plan until then

## AI Models and Plans
