Ginger is third on this list because of its feature-full corrections in different aspects of writing. Some argue that it can correct all textual errors, including spelling and grammar, and complex sentences. But I think mechanical errors are its cup of tea.

The online editing tool allows the writer to access synonym and idiom suggestions. Some recommendations are unhelpful, but the tool proves valuable to users who need assistance in rephrasing.

Ginger also lets you translate your text into 40 different languages. Any writer, academician, and public relations officer will find this tool useful. It’s also more convenient for non-native English speaker to improve their writing. 

The online spellchecker uses natural language processing for this unique feature. That means it could make more accurate translations than Google Translate.

Aside from the usual grammar service that corrects common grammar mistakes, Reverso also has a translation tool. Any professional writer will enjoy translating their text into French, German, Italian, Portuguese, Hebrew, etc.

It also has a robust spell and punctuation checker that works like any spellchecker. It underlines incorrect use of the comma, “your” vs. “you’re,” and other obvious mistakes. Reverso also enhances your word list or phrases while correcting passive sentences.

One downside to this editor is its inability to correct complex sentence formation. It also has strict limitations and a lack of a plagiarism checker.

On the bright side, the tool offers a browser extension for real-time editing. Download the Google Chrome browser app and click the “Add Reverso to Chrome” button. The extension lets you view your search history and save your favorites for future use.

Importance of Using a Spellchecker

Even the best writers commit spelling errors in their work. That is why their works undergo thorough editing before getting published.

A spell-check program is necessary to help them double-check any mistake they might have overlooked. These tools either highlight or underline any error, then provide accurate suggestions.

Some spell checkers also flag grammar or incorrect writing style. Their ability to fix these mistakes gives them more time to do other tasks. If you keep spelling a term wrong, this online tool will help you find the word and change it with the accurate spelling.

If you work as an editor, you’ll have more time to assess other parts of the writing. You can focus on strengthening the character development of a story or proper contextualization of a research proposal. 

Lastly, a good spellchecker lets you standardize your document. Add proper nouns like business names and brands to your custom dictionary so that it won’t flag the term as a misspelling. 

Common Errors a Spelling and Grammar Checker Can Fix

Here are some common errors that an excellent spelling and grammar checker can identify and fix.


A basic spell check should check each in your piece of writing for any spelling mistakes. But you can also opt for advanced tools that provide contextual spelling errors. 

For example, both “their” and “they’re” are correct spellings. However, you might misuse them in some contexts. An excellent spelling tool should be able to tell which word you should use.


A good grammar checker not only corrects subject-verb disagreements in your sentences. It should also consider other rules, such as the fact that adjectives must come before the noun. 

State-of-the-art programs also spot squinting modifiers, unnecessary adverbs, and improper use of prepositions at the end of sentences. Others detect improper usage of indefinite articles with countable and uncountable nouns.


A good spell checker must consider punctuation rules in their system. It’ll help the reader understand your text better, guiding them into pausing, stopping, emphasizing, or quoting statements. In other words, correct punctuation makes your writing clearer and more precise. 

Grammarly has an extra feature that differentiates between straight and curly apostrophes. Follow its suggestions so you can observe the consistency in your punctuation marks.

Writing Style

The best spellcheckers also offer “near-human” characteristics to your writing through writing style suggestions. It should help you with your sentence lengths, active voice, overall readability, and other insights into your text.

For example, ProWritingAid provides reports on your repeated words and phrases. It can also spot your text’s sticky sentences, cliches, and redundancies. 

These writing style recommendations ensure that your online program isn’t only dedicated to correcting your mistakes. Instead, it also intends to make you a better writer. 

Choose Your Spellchecker Wisely

Proofreading your work should be easier with these ten online spell-checking software. Each editing tool has features to improve your document and overall writing skills.

These spellcheckers also have their own strengths and weaknesses. Some are ideal for businesses, while others are for students and creative writers. Make sure to choose a program that caters to your writing needs.
