Switching between monthly and annual billing

You can switch between monthly and annual billing at any time without cancelling and re-subscribing.

Switch from the billing portal

  1. Click your name in the sidebar and choose Manage Plan.
  2. Click Manage Subscription to open the Stripe billing portal.
  3. Choose Update plan.
  4. Pick Pro — Monthly or Pro — Annual (or the Organization equivalent) and confirm.
The My Plan page for a Pro account. Top section reads 'Your current plan: Pro' with a 'Current billing cycle: (May 4, 2026 - Jun 4, 2026)' bar and '30 days left' label. Two action sections follow: 'Manage Subscription' ('Adjust your billing information, cancel your subscription, or change your plan securely.' with a black Manage Subscription button — this opens the Stripe customer portal) and 'Cancel Subscription' ('Cancel your subscription at the end of the billing period.' with a red Cancel Subscription button).
Manage Plan page with the Manage Subscription button (Pro view)

Stripe will calculate any proration automatically:

  • Monthly → Annual: you're charged the annual amount, with a credit for the unused portion of your current month.
  • Annual → Monthly: the change usually takes effect at the next renewal, keeping you on annual until then. Stripe will show the exact dates before you confirm.

After the change

  • Your Pro features continue uninterrupted.
  • Your chat history, library, and personalization are unaffected.
  • Future invoices reflect the new cadence.
