Which plan to pickStart on Free. If you translate documents or customer emails every week, Individual on a yearly plan is the sweet spot and stops DeepL keeping your text. Move to Team only when several people need the same glossary.Start on Free. Pro is cheap and covers about 250 pages a month, enough for most individuals. Take Team once more than one person translates, because users are free and you only pay for the shared quota.Test the free 250 words on your own writing first. If the output works for you, a small yearly plan is cheap. Word credits reset monthly, so don't buy more than you use.
