Which plan to pickTry the free checker first. Personal covers about 100 pages a month, which suits most individuals. Only move to Pro if a team needs seats or you want website scans. One credit covers 250 words or one image.Use the free app and website. Only look at the Cloud Translation API if you're building translation into your own website or system.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.
