Who each one suits

Antidote

  • People who write in both English and French
  • Editors and translators who want explanations with each correction
  • Families: one subscription covers five users
  • Organizations that need a corrector installed without external servers

ProWritingAid

  • Fiction writers who want feedback on a chapter or a whole manuscript
  • Authors who edit in Scrivener, Word or Google Docs
  • Writers who would rather buy a lifetime license than subscribe

Worth knowing

Antidote

  • Druide's store lists prices in Canadian dollars, plus taxes where applicable.
  • The subscription is billed once a year with no monthly option, and store purchases are not refundable.
  • English and French are separate: one language is included, and having both costs CA$89.95 instead of CA$59.95.
  • There is no native Android app. Android, Chromebook and Linux users work in Antidote Web, and Antidote Mobile has no corrector of its own.

ProWritingAid

  • The Free plan checks at most 500 words at a time and allows 2 runs of each report per day.
  • Manuscript Analysis, Virtual Beta Reader and the other full-story tools need Story Credits, bought separately from a subscription.
  • An internet connection is required for the Web Editor and every integration, including the desktop apps.
  • Plagiarism checks are sold separately in bundles, and each check covers up to 2,000 words.
