Take Team once more than one person translates, because users are free and you only pay for the shared quota. | 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. |
