5 AI-Based Grammar Checkers to Elevate Your Writing 

The hype around artificial intelligence (AI) has continued and many people have become desensitized to the news related to this technology. However, ignoring the use cases of AI and its significant advancements would be a mistake. While AI falls short in some areas, there are some areas where AI has already brought substantial improvements. For example, grammar checkers have become more powerful and effective.

With multiple affordable options available, there’s no excuse not to use a grammar checker. These tools are constantly updated with new features and improved accuracy, making them real copilots for writers.

The following AI-based grammar checkers will help you polish your writing, improve your messages and emails, enhance your style, and avoid typos and misspellings.



Do you need a grammar checker that works everywhere? Grammarly has you covered. It seamlessly integrates with your devices, from your Windows PC to your iPhone, and even offers extensions for all major browsers like Chrome, Firefox, Safari, and Edge. No matter where you’re writing, Grammarly ensures polished, professional writing.

Grammarly’s standout feature is its comprehensive set of grammar and punctuation checks. Once Grammarly checks your writing, you can be confident it’s error-free. However, Grammarly’s capabilities extend far beyond a simple grammar check. Use it to do the following tasks:

  • Suggest vocabulary enhancements;
  • Detect the tone of the message and help you align the tone with your intention;
  • Provide an AI assistant, GrammarlyGO, to streamline your work;
  • Scan texts for plagiarism;
  • Measure and drive the progress of the team’s users.

Best for: Everyone.

Pricing: Grammarly has a free version that eliminates writing mistakes but doesn’t offer many options to enhance your texts. The cheapest pricing plan is 30 EUR/month or 12 EUR/month, billed annually, which situates Grammarly in the top list of the most expensive AI-based grammar checkers on the market. However, you get real value for your money. If you are a content creator or write many emails daily, then Grammarly is almost mandatory for you!

Hemingway App


Hemingway App is one of the oldest and most efficient tools for writers. Initially, this application focused on highlighting complex sentences, passive voice constructions, and excessive adverb usage. The simplicity and effectiveness of the tool contributed to its massive success. Another highly appreciated feature is its color-coded suggestions. For instance, sentences highlighted in red are hard to read, while adverbs are marked in blue. Hemmingway App is the perfect choice if you are looking for a tool to make your writing concise, clear, and error-free.

Hemingway App isn’t an exception and has been updated to incorporate an AI module. Hemingway Editor Plus is a premium feature aimed at helping you improve your writing by leveraging AI. It provides alternatives for unclear wording and refines your style.

Linguix is a solid alternative to Grammarly and one of the best AI-based grammar checkers. It helps users write better, clearer, and error-free content.

  • Checking texts for grammar and spelling errors;
  • Creating content;
  • Finding better rephrases, alternatives, and synonyms for words and expressions;
