| Which plan to pick | Start 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. | Stay on Free if you only reword the odd sentence. If you use it every week, the yearly Premium plan is far cheaper than paying monthly, but set a reminder before it renews because refunds after renewal are hard to get. | Use the free trial on a real chapter first. If you're drafting a full book, Professional is where most novelists land; only move to Max if you're running out of credits every month. |
