All paid subscriptions include 1 million characters per day to convert. If on a Team License, it is also 1 million per day per user. For comparison, 1 million characters would be equal to about 330 single-spaced pages of a Word document using size 12 font. Most Commercial users convert an average of 10,000 characters per day.
There are also some limitations for how much text can be converted in the single segment as well as for the maximum size of projects.
When you enter text to create a new project, it will divide up the text based on where paragraph breaks occur. These segments can have a maximum of either 800 or 1500 characters, depending on the voice being used, and each project and maximum of 100 segments. But, you can create an unlimited amount of projects.
