Pricing that scales with you

Credits are a dollar-denominated balance used to pay for usage across all Inworld products. When you subscribe to a paid plan, you receive credits equal to your plan price at the start of each billing cycle. For example, the Developer plan ($300/mo) grants $300 in monthly credits. As you use Inworld products, usage is metered and deducted from your credit balance at your tier's rates. Higher tiers unlock lower per-unit rates and higher rate limits across various features/products.

Unused subscription credits roll over automatically for up to 3 months, as long as you have an active paid subscription and a plan of equal or higher value. Each month's credit grant has its own 3-month window before it expires. For example, if you have $50 unused from January, that $50 expires at the end of March.

You can purchase additional credits or enable auto-reload to automatically add credits when your balance drops below a threshold you set. These credits are billed at your current tier's rates and expire after 1 year from purchase. They are not subject to monthly expiration or rollover limits.

Upgrades take effect immediately. The amount charged is the difference between your current plan and your new plan, pro-rated for the remaining days in this billing cycle, and inclusive of any outstanding usage. Any unused credits roll over and are added to your new balance. Downgrades and cancellations take effect at the end of your current billing period, at which point any remaining credits are forfeited.
