Pros and cons
From each tool's full review, written from the same checked facts.
Grammarly
- Grammarly works across an impressive range of platforms including Chrome, Safari, Firefox, Edge, Windows, Mac, iOS, Android, Microsoft Word, and Google Docs.
- The plagiarism checker is built directly into the editor rather than being a separate export tool, a useful workflow for academic and content marketing use.
- Real-time grammar, spelling, and punctuation corrections remain reliable and are available even on the free plan.
- The Pro plan at $12/month billed annually unlocks full sentence rewrites, tone suggestions, and style clarity options at a competitive price point.
- Tone detection and brand voice features make it viable for enterprise teams managing content consistency across large organizations.
- Grammarly says it works across more than 500,000 apps and websites, making it one of the most broadly compatible writing tools.
- The free plan is significantly limited, though it does include tone detection and 100 AI prompts a month alongside basic grammar, spelling, and punctuation; most meaningful features still require a paid Pro subscription.
- Grammarly is now owned by Superhuman, which adds uncertainty about the product's long-term direction.
- Brand voice customization is heavily gated, with free users restricted to a single brand tone while unlimited options require an enterprise plan.
Wordtune
- 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.
- 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.
