Credits are the currency used to pay for translation and automation tasks on DocTranslate. Each task deducts a certain amount of credits from your balance based on its size and type.

Go to Plan in the sidebar (or the Credits recharge button in the header) to subscribe to a plan or top up credits. New accounts start with 5 free credits to try every module.

The exact cost depends on the task — word count for documents, page count for scans/images, or minutes for audio/video. DocTranslate always shows a cost estimate before you confirm, so there are no surprises.

We'll let you know when your balance is too low for a task and prompt you to top up or upgrade your plan before continuing.
