Best Free Alternatives to Grammarly

What's free: You get 125 words per paraphrase request, basic grammar/spelling checks, summarizer (up to 1,200 words), and 3 synonym options. The free plan includes standard fluency mode and one freeze word feature.

Limitations: No plagiarism checker, limited to 1,200 words for summarizer, slower processing speed, basic modes only, and watermark on some outputs. The paraphrasing quality is noticeably better in premium.

Best for: Students and non-professional writers who need quick paraphrasing help for essays or basic content rewriting.

What's free: You receive 10 rewrites per day, basic grammar and spelling corrections, and access to the 'Shorten' and 'Casual/Formal' tone features. The browser extension works on most websites.

Limitations: Only 10 daily rewrites, no premium features like 'Spices' (adding statistics or jokes), no unlimited synonyms, and no team collaboration features. The free plan feels restrictive for daily use.

Best for: Professionals who need occasional sentence refinement for emails or social media posts, but don't require heavy daily usage.

What's free: You get 2,000 words per month in the chat-based workflow, access to 90+ copywriting templates, and the basic blog wizard. The free plan includes one user seat.

Limitations: No unlimited generation, no plagiarism checker, no brand voices, no project folders, and no priority support. The 2,000-word limit disappears quickly for serious content creation.

Best for: Solopreneurs and small business owners testing AI content generation for marketing copy before committing to paid tools.

What's free: You receive 10,000 premium words per month (recently reduced from more generous limits), access to GPT-4o, and all core features including Article Writer 5.0 and Chatsonic.

Limitations: The 10,000-word cap includes both input and output, no custom brand voices, limited image generation, and no team collaboration. The word count burns fast when using advanced features.

Best for: Content marketers and bloggers who need high-quality AI writing for articles but can work within strict monthly word limits.

What's free: You get 10,000 characters per month (about 2,000 words), access to 40+ use cases, 30+ languages, and 20+ tones. The free plan includes basic plagiarism checks (5 per month) and the browser extension.

Limitations: Very limited character count, only 5 plagiarism checks monthly, no custom use cases, no dedicated account manager, and no priority support. The character limit makes it impractical for regular use.

Best for: Casual users and students who need occasional AI writing help for short-form content like emails or social posts.

What's free: The web version is completely free with no sign-up required. You get real-time readability scoring, highlighting of complex sentences, adverb detection, passive voice identification, and basic formatting.

Limitations: No grammar checking beyond basic errors, no spelling correction in the free web version, no plagiarism detection, no tone analysis, and no integration with other apps. It's purely a readability tool.

Best for: Writers, editors, and bloggers who want to improve clarity and conciseness in their writing without AI rewriting features.

What's free: You get 10 AI responses per day, basic email and message drafting, tone adjustment for professional communication, and browser extension access.

Limitations: Only 10 daily responses, no advanced email analytics, no team features, no custom templates, and no priority support. The free tier feels more like a trial than a sustainable option.

Best for: Professionals who need occasional help drafting professional emails but don't require daily AI assistance.
