Which plan to pickStart 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.Start on Free. Pro is cheap and covers about 250 pages a month, enough for most individuals. Take Team once more than one person translates, because users are free and you only pay for the shared quota.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.

Cons

  • Free characters run out quickly on long documents
  • Prices on the website are yearly; monthly costs more
  • Free plan caps paraphrasing at 125 words per go and hides most modes
