The verdict

Wordtune wins, 5.8 to 3.9

Wordtune's Advanced plan is $13.99 a month, under half of ProWritingAid Premium's $30. Wordtune writes new text from a prompt; ProWritingAid only rewrites and checks text you already have, with no blank-page generation found. ProWritingAid checks for plagiarism through separate credits, a feature not present in Wordtune's known facts. ProWritingAid says it does not train its AI on your writing at all, while Wordtune lets users opt out but defaults training on.

Pick ProWritingAid if you want plagiarism checking without opt-out AI training.

Pick Wordtune if you want cheaper text generation and don't need plagiarism checks.

Pros and cons

From each tool's full review, written from the same checked facts.

ProWritingAid

Pros
  • Offers 25+ writing reports including pacing analysis, dialogue tag tracking, and repeated phrase detection that go far beyond surface-level grammar checks.
  • Integrates with Scrivener, a major differentiator over Grammarly that fiction writers in long-form workflows genuinely value.
  • Works across multiple environments including a web editor, desktop app, Chrome extension, Microsoft Word, and Google Docs.
  • The Chapter Critique feature provides AI-driven feedback on entire chapters at once, approximating developmental editing rather than simple grammar correction.
  • The Virtual Beta Reader simulates reader response feedback on manuscripts, offering fiction writers access to a resource they may not otherwise have.
  • Sparks feature helps writers push through creative blocks by offering AI-powered inspiration and continuation mid-chapter.
  • In development since 2012, giving it a long track record in writing software.
  • Manuscript-level depth of analysis is available at a comparable price point to competitors that offer far less specialized feedback.
Cons
  • Runs on a proprietary AI model with no recognizable third-party AI partnership, which may raise questions about model quality and transparency.
  • The tool is heavily specialized for long-form fiction writers, making it potentially overkill or poorly suited for casual or business writers.
  • The large number of reports (25+) can feel overwhelming and may require significant time investment to use effectively.
  • Does not offer GPT-4 or similarly branded AI integrations that some competing tools use to establish credibility.
  • Users coming from Grammarly may face a learning curve given the depth and complexity of ProWritingAid's feature set.

Wordtune

Pros
  • Built on proprietary AI models from AI21 Labs, not a generic GPT wrapper, giving it a distinct output style.
  • Fact-verified AI suggestions claim to cross-check generated content against five or more sources before surfacing.
  • Rewriting and paraphrasing tools offer tone and length adjustments in a fast, focused loop most users rely on daily.
  • Available across web, Chrome extension, iOS, Android, and Google Docs for broad accessibility.
  • Long-form writing mode supports essay structure and includes source citations for generated facts.
Cons
  • No WordPress integration, limiting utility for content publishers who work directly in CMS environments.
  • No publicly confirmed API access, making it difficult to embed into custom workflows or developer tooling.
  • Grammar and style analysis is less deep than Grammarly, so it may not satisfy users with advanced proofreading needs.
  • Fact-verification claims are difficult to independently validate and should be treated with caution in practice.
  • Not designed for long-form content generation, making it a poor fit for users seeking a Jasper-style content engine.
  • Focused feature set means users needing an all-in-one AI writing platform will likely need additional tools.
