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.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.
