Free Grammarly Alternatives
Three verified free AI writing options besides Grammarly Free - ChatGPT, 1min.AI and Mistral - with real limits, card rules, and the catch for each.
Phần này hiện bằng tiếng Anh.
Grammarly Free checks spelling, grammar and tone and gives 100 AI prompts a month; rewriting whole sentences, adjusting tone, fluency suggestions and plagiarism or AI-text detection are Pro features at $12 a month, per Grammarly’s plans page. The verified options below do not copy its in-line checker. They give you a chat assistant that can proofread, rewrite and change tone on request: ChatGPT’s free plan with unlimited text chats, 1min.AI’s all-in-one workspace with daily free credits, and Mistral’s free plan with limited messages. Every row is a live offer from the same catalog as the free AI coding tools directory, re-checked monthly. The free AI writing assistants guide covers Gemini, Claude, Notion AI and Microsoft Copilot, whose free plans are not catalog rows yet.

Câu hỏi thường gặp
Phần này hiện bằng tiếng Anh.
- Is Grammarly free?
- Yes, the Free plan is $0 a month: it flags spelling and grammar mistakes, shows the tone of your writing and gives 100 AI prompts a month. One-click sentence rewrites, tone adjustment, plagiarism and AI-text detection need Pro at $12 a month. These details were read from Grammarly’s plans page on November 1, 2026.
- What is the best free alternative to Grammarly?
- For fixing and rewriting text on demand, ChatGPT’s free plan: unlimited text chats, so you can paste a draft and ask for proofreading or a different tone. It has no browser-wide checker like Grammarly’s extension, so you copy text in and out.
- Do these Grammarly alternatives need a credit card?
- No - none of the three rows asks for a card. The catches differ: ChatGPT limits file uploads and deep research, 1min.AI keeps files for three days on the free plan, and Mistral limits messages and web searches.
- Do these tools check writing as I type?
- No. They are chat assistants, not inline checkers: you paste text and ask for a fix. If you want underlines inside every text box, Grammarly Free is still the baseline.
