Which plan to pickUse 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.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.Test the free 250 words on your own writing first. If the output works for you, a small yearly plan is cheap. Word credits reset monthly, so don't buy more than you use.
