Feature-by-Feature Comparison
Let’s break down the key features of LanguageTool and Grammarly to see how they stack up.
Grammar & Spell Checking
Both LanguageTool and Grammarly offer robust grammar and spell-checking capabilities. However, the depth and focus differ. Grammarly Premium excels in clarity, engagement, and overall delivery, providing suggestions to make writing more polished and impactful. LanguageTool’s “Picky Mode” brings a more nuanced approach, flagging issues with word choice, punctuation, and expression for a refined result.
Paraphrasing Capabilities
Paraphrasing tools can significantly enhance writing by making sentences clearer, more formal, or more concise. LanguageTool offers paraphrasing with options like “formal” or “simple,” but the free version is limited to three paraphrases per day, and only one sentence at a time. Grammarly’s paraphrasing tool is more flexible, allowing users to adjust tone, length, and formality. Grammarly can paraphrase entire paragraphs, while LanguageTool is limited to single sentences. Free Grammarly users get 100 AI prompts per month for paraphrasing, while premium users get 2,000.
AI Integration
Generative AI is transforming how we create content. Grammarly can generate outlines, brainstorm ideas, write email drafts, and tailor content to different tones or formats. LanguageTool currently lacks generative AI features. If you need help creating content from scratch, Grammarly has a clear advantage.
Platform Support & Integration
The accessibility of a writing tool is crucial for seamless integration into your workflow.
Device Compatibility
Both LanguageTool and Grammarly are available as desktop apps for Mac and Windows, browser extensions for Chrome, Safari, Firefox, and Edge. However, LanguageTool does not have an Android app, which may be a drawback for some users.
Language Support
LanguageTool supports over 30 languages and six English dialects, including US, UK, Australian, and Canadian English. Grammarly focuses primarily on English, with options to switch between dialects. If you write in multiple languages, LanguageTool is the better choice.
Pricing Analysis
Cost is a significant factor when choosing a writing assistant.
Cost Comparison
LanguageTool’s premium plan is more budget-friendly at $24.90 per month or $69.90 per year. Grammarly Premium costs $30 per month or $144 per year, almost double the annual cost of LanguageTool.
Free vs Premium Features
Both tools offer free versions with basic features. Grammarly’s free version includes a higher character limit (100,000) compared to LanguageTool (10,000). However, premium versions unlock advanced capabilities like style suggestions, plagiarism checks, and team features.
