1. Grammarly.

Best for Error-free Proofreading

Grammarly Homepage

Grammarly started operations in 2009 and has positioned itself as the leading grammar and spell-checking tool on the market. It towers over others because you get to check spelling and grammar as well as spot contextual errors, improving your writing skills.

It lets you perform checks in multiple languages such as Australian, US, and UK English. The tool also has provisions for plagiarism checking and provides suggestions regarding how you can improve the quality of the text you’ve written.

One of the aspects of Grammarly that I find enticing is that it comes with an easy-to-use browser plugin. Once you’ve included that in your browser, you can run Grammarly checks while composing emails and writing in Google docs.

Such detailed checking makes the writing process fluid. With the Grammarly extension, you’ll never be caught off-guard by errant spelling, punctuation, and other writing mistakes. Also, the interface and error prompts are very user-friendly, so that’s another advantage.

Features:

Grammarly uses advanced AI and Natural Language Processing (NLP) techniques to analyze your text. The writing assistant tool highlights sentence structure and style problems and can even help you make your text more concise, clear, and understandable.

The following lists some of the features that Grammarly offers:

  • Multi-language support
  • Plagiarism checker
  • Content quality score
  • Easy integration with most business apps

Using Wordtune, you can work to make your content more compelling, engaging, and easily consumable. To help you achieve this, the service uses advanced, neural-net-based NLP technology combined with standard AI tools.

The tool paraphrases the content you’ve written and rewrites it more fluidly and understandably. It attempts to improve the readability of the text instead of regular grammar checking that focuses more on syntax than semantics.

Wordtune helps you write sentences that read great and at the same time preserve the original meaning. It provides you with several different options for every sentence that you need to rewrite.

Apart from the above, the following are some of the other features Wordtune offers:
