Premium AI shares a generous monthly fair-use budget. Profile, then Usage, shows how much you have used. Exact daily limits for each feature are listed in our Terms of Service.
How billing works
- Premium is an auto-renewing subscription. It renews at the end of each period until you cancel.
- On the web you pay through Stripe and need to be signed in. On iPhone you pay through Apple, and the price may be shown in your local currency.
- Cancel any time in Profile, then Settings, then Manage subscription. You keep Premium until the end of the period you paid for.
- Prices above are U.S. list prices. Tax may apply.
AI credit packs (web)
Need a little more without subscribing? On the web you can buy a one-time credit pack. Packs never renew. One credit equals one flexible AI use.
| Credits | Price |
|---|---|
| 100 credits | $2.99 |
| 300 credits | $6.99 |
| 1,000 credits | $19.99 |
