Your free trial
New authors get a 14-day free trial of the Professional plan, with every feature, and no card required. While it runs, a banner shows how many days are left.
If you don't choose a plan, your account moves to the Free plan when the trial ends. Nothing is charged, and your writing stays readable and exportable.
To keep your features, choose a plan any time before the trial ends.
