Microsoft Word was first released in 1983 and has remained the popular spell check software for Windows.

This word processor is currently available as a standalone product and as a component of the Microsoft Office software suite. If you add a word to a custom dictionary in any MS Office program, it makes that word available for spell checks in all Office programs.

The Microsoft Word word processor is already installed on many computers, making it one of the handiest spell check tools available.

Pros
  • Microsoft Word's spellchecker is available at no extra charge
  • Microsoft Word works offline, so it doesn’t require internet connectivity
Cons

Price: Free, $30 per month for Professional membership 

AutoCrit Spell checker
AutoCrit can suggest synonyms without taking away from your unique voice

AutoCrit is a spell-checking and editing tool for fiction writers.

If you're an author, you probably want to spend as little time as possible scanning your work for potential spelling mistakes. So, AutoCrit can help you clean up your manuscript before submitting it for publication.

It also expands well beyond this niche. It can scan your work for repetition, pacing, and evaluate your words of choice. So, you don't need a thesaurus on hand.

This can help see if you're on the right path when it comes to getting your manuscript published within a certain genre.

Free Vs. Paid Spell Check Software

Today's spellcheck is either free of charge or may incur a monthly fee, depending on your requirements. The latter has more advanced grammar features, but that doesn’t mean a free spell-check tool isn’t useful.

Generally, to use the paid ones, all you need to do is insert your text, by uploading a file or copying it into the program and allowing it to get to work. Then you accept changes to any misspelled words, punctuation errors, or grammatical errors that are highlighted, or revert back to the original version.

Commercial spell check software or virtual writing tutor providers sometimes offer trial versions of their software at no charge, which typically have fewer features and more limited spell capabilities than paid versions.

The features included in a paid spell checker and grammar tool are of value to serious writers.

These include the correction of any unrecognized word, phonetic mistakes, spelling mistakes, punctuation mistakes, passive voice checking, sentence structure checking, and checks for other grammatical errors. Some of them even have an inbuilt plagiarism checker.

All this can help give your writing proper grammar and more professional quality.

Paid grammar software also tends to have more extensive dictionaries so that no false mistake or English grammar error gets reported. Some of them also let you add words to a custom dictionary.

This capability is particularly essential for technical writing, which uses everyday words differently. For example, you needn’t capitalize the term “agile” when used as a common word. However, you need to capitalize when referring to “Agile software development.”

A paid checker is more likely to allow the addition of words to its dictionary, which helps check for any spelling error or grammar error on proper nouns.

English and multi-language capability is another common benefit of paid spell checker software. For example, “colour” will be highlighted as a misspelling in US English, but it is used in UK English. At the same time, “color” is the correct spelling in US English.

Your readers may notice a mechanical writing error or a spelling error more often than you might expect, which distracts them from your message. Spelling checkers will catch phonetic spelling mistakes, typos, irregular verb conjugations, similar-sounding word errors, on top of plenty of grammatical mistakes.

A thorough understanding of English spelling rules is essential for professional or academic writing, and even to enter any spelling test.

The best spell check software tools charge a monthly fee instead of a one-time cost. However, don’t dismiss free spell check software tools, which are surprisingly powerful.
