# 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.

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](https://aifree.dev/free-ai-coding-tools), re-checked monthly. The [free AI writing assistants guide](https://aifree.dev/learn/free-ai-writing-assistants) covers Gemini, Claude, Notion AI and Microsoft Copilot, whose free plans are not catalog rows yet.

## Frequently asked questions

### 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.
