15 Best Free Grammarly Alternatives You Should Try in 2025

Grammarly has become one of the most popular tools for checking grammar and improving writing. It helps people fix errors, rewrite sentences, and sound more natural when writing emails, essays, or reports.

But while Grammarly is widely used, it’s not the only option available. Many other AI grammar checkers and writing tools offer similar or even more specialized features (often for free).

In this article, we'll cover the 15 best free Grammarly alternatives that you can use to improve your writing with AI in 2025. Let's dive in!

What is Grammarly?

Grammarly is a grammar checker that helps you improve your writing. It scans your text for grammar, spelling, punctuation, and clarity issues.

Grammarly gives real-time suggestions to help you make your writing more natural and professional. It also offers AI writing tools that help you rewrite or improve your writing with the help of AI.

How to Use Grammarly

Grammarly can do more than just fix typos. It works as a complete writing assistant that checks grammar, improves style, and helps you rewrite text with AI.

Here are a few ways that you can use Grammarly:

Checking grammar

Grammarly’s grammar checker scans your text for spelling, punctuation, and grammar mistakes. It highlights issues in real-time and provides explanations for each correction. This helps you learn from your mistakes and write more accurately over time.

AI writing

The AI writing feature helps you generate or refine sentences when you need better wording. It suggests improvements for clarity, structure, and flow. You can use it to strengthen arguments, make sentences more natural, or expand short drafts.

AI checker (detection)

Grammarly’s AI checker reviews your writing for readability and tone. It identifies awkward phrasing, inconsistent style, or unclear sections. This helps you polish your writing to make it sound more professional and consistent.

Paraphrasing

The paraphrasing feature lets you rewrite sentences to match a different tone or style. You can make your writing more formal, simpler, or more conversational depending on the goal. It’s especially useful for rewording repetitive text or improving sentence variety.

Is Grammarly Free? How Much is Grammarly Premium?

Grammarly offers a free plan, but to get full access to AI writing and suggestion features, you have to upgrade to a paid plan.

Many people ask whether Grammarly Premium is worth it, and that really depends on what your needs are. Keep in mind that there are plenty of similar tools that offer similar features for a lower price.

While Grammarly is useful, it's high price tag can be a reason for many people to look into alternatives.

Is Grammarly Worth It?

Grammarly is useful for people who write often and want help catching small grammar or tone issues. It saves time by checking errors in real-time and suggesting ways to improve clarity and flow.

However, Grammarly’s best features—like tone rewrites, full-sentence suggestions, and plagiarism checks—are only available in the paid version. If you just need basic grammar checking or occasional AI writing help, many free Grammarly alternatives can do the job just as well.

What to Look for in Grammarly Alternatives

Some Grammarly alternatives focus on features that Grammarly doesn’t offer or only includes in paid plans. These extra benefits can make them more flexible and accessible for different types of writers.

Here are some things to look for when choosing a Grammarly alternative:

• Free or cheaper plans - Many alternatives give you grammar and writing tools without expensive subscriptions or strict limits.

• Privacy-focused options - Some tools don’t store or share your data, letting you write and edit safely without cloud tracking.

• AI writing help - Look for tools that go beyond grammar checking to help you rewrite, expand, or summarize text using AI.

• More language support - Several alternatives support multiple languages, making them ideal for bilingual or international writers.

• Works anywhere - The best tools integrate with browsers, documents, and messaging apps so you can check writing wherever you type.

Choosing the right free Grammarly alternative depends on what matters most to you—cost, privacy, flexibility, or extra AI writing features.
