Costs are weighted by what each action takes to run, so a credit is worth the same to you whichever feature spends it.

Good to know

Failed requests are free. Credits are only spent on a result you actually get. If a translation times out or fails, the credits go back automatically.

Length does not change the price. A translation costs 1 credit whether it is a single word or a full paragraph. The words-per-translation limit is what caps how much you can select at once.

Credits reset daily. Your balance refills every day at midnight, in your own time zone. Unused credits do not carry over.

Replays are free. Playing audio you have already generated costs nothing, because it is stored on your device.

You can see your balance any time in the Sori sidebar, and on your account page. Hover the credit icon in the sidebar for a reminder of what each feature costs.
