Publishers and large content teams.

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.Pro is enough for most agencies and site owners. An AI and plagiarism check together uses two credits per 100 words, so budget about 100,000 words of checked content a month. Go Enterprise only if you need the API or very high volume.
