• The Free plan allows 10 autocompletes a day, 10 library uploads and 5 AI Chat messages, and exports body content only.
• Monthly billing costs far more than annual: $30 against $12 a month for Plus, and $73 against $29 for Pro.
• Plus caps Reviews and workflow runs at 10 a month each; only Pro removes the limits.
• No desktop or mobile apps are listed. The web app is described as working on mobile and desktop devices.

Paperpal

• The Free plan stops at 200 grammar edits a month and 5 uses a day of the paraphrase, translate and research tools.
• Plagiarism checks have a monthly word cap on every paid plan; going over it means buying a one-time add-on valid for a month.
• The one-time multi-year option exists for Prime only, and the full Journal Fit report needs Pro.
• No desktop or mobile app is listed: it runs on the web, in a Word add-in and in Chrome and Edge extensions.
