| 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. | Free is enough for typo-catching. If you write for clients or customers every day, Pro on yearly billing is good value; paying monthly costs more than double. | Try Free on a chapter or a long blog post. If it clicks, Premium on yearly billing is good value, and the lifetime deal pays off after about three years. Premium Pro is for authors who want daily critiques and the workshops. |
