| Which plan to pick | 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. | Use the free editor first. If you want the fixes done for you, try Editor Plus free for two weeks. Individual 10K is the best value if you write most days. Monthly billing is available but costs more than yearly. | 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. |
