BRIEF can't exceed 12,000 characters for inputs.
Presently, BRIEF has a limit of 12,000 characters for input.
If you need to edit or manipulate your text to ensure that the 12,000 characters you want briefed are contained within the text box, you can edit prior to generating your summary. If your text exceeds 12,000 characters and you don’t edit your input, all characters after 12,000 will not be included in the summary logic.
Below is the error message you will receive if you try to run a summary that exceeds 12,000 characters. By clicking “YES,” BRIEF will generate a summary on the first 12,000 characters. By clicking “EDIT,” you will return to the input screen.
