Which plan to pickUse the free app and website. Only look at the Cloud Translation API if you're building translation into your own website or system.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.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.
