How can I upgrade my existing QuillBot Premium plan?

If you already have a QuillBot Premium subscription and want to switch to a longer billing cycle, for example, from monthly → quarterly or from quarterly → annual, you can upgrade your plan anytime from your Account Details page.

To upgrade your subscription

1. Go to your Account Details page by clicking your profile icon (the circle with the first letter of your name) in the top-right corner of the QuillBot website and selecting Account Details.
2. In the Your Plan section, click Change plan.
3. Choose your preferred plan: quarterly or annual.
4. Review the confirmation message showing the amount you’ll be billed.
5. Click Confirm to complete the upgrade.
   

Note: You’ll be billed immediately for the upgraded plan, and your new billing cycle will start right away.

Once complete, your subscription will automatically reflect the upgraded plan.
