The verdict

Wordtune wins, 5.8 to 5.2

Wordtune writes new text from a prompt and offers a phone keyboard on iOS; LanguageTool does neither, focused instead on checking text you already have. LanguageTool includes an API and a personal dictionary, both missing from Wordtune's known facts. Wordtune's Advanced plan is $13.99 a month, well under LanguageTool Premium's $25.48. LanguageTool states it does not train its AI on your writing at all, while Wordtune lets users opt out but defaults training on.

Pick LanguageTool if you want an API, personal dictionary and no AI training.

Pick Wordtune if you want text generation and a phone keyboard at a lower price.

Pros and cons

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

LanguageTool

Pros
  • Supports grammar, style, and spelling checking across 30+ languages including multiple dialects, making it genuinely useful for multilingual users.
  • Has been operational since 2003, predating most competitors including Grammarly, indicating long-term stability and refinement.
  • Integrates across a wide range of surfaces including Chrome, Firefox, Edge, Safari, macOS, Windows, Google Docs, Microsoft Word, LibreOffice, Gmail, Outlook, Apple Mail, and Thunderbird.
  • Picky Mode offers an adjustable level of style critique, letting writers choose how aggressively the tool pushes back on their writing.
  • The AI paraphraser has five rewriting modes (general, formal, concise, fluent and simple) for sentence-level refinement.
  • Personal dictionary feature allows technical writers and specialists to add field-specific terms, reducing false positives.
  • Style Guide feature at Premium and Teams levels enables organizations to enforce custom writing rules consistently.
Cons
  • The tool is narrower in scope than competitors like Grammarly, which may disappoint users expecting a full-featured writing assistant.
  • AI functionality is limited to sentence-level paraphrasing and is not a content generation platform, which will confuse users expecting Jasper-like capabilities.
  • Advanced features like the Style Guide are locked behind Premium and Teams pricing tiers, limiting value for free users.
  • Depth of checking may not match the breadth of language support, meaning multilingual users could find suggestions inconsistent across languages.
  • Users with specialized vocabularies face friction until they manually build out their personal dictionary to avoid repeated false corrections.

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.
