| 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. | Start on Free. If you check more than a few documents a week, Premium on yearly billing is the sweet spot. Professional only makes sense if you scan big batches of files. | 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. |
