About spelling and grammar checkers

Spelling and grammar checkers evaluate what a user types and suggest corrections when errors are found. Corrections can occur either when users request them, or automatically as users type.

What is a grammar or spell check API?

A spelling or grammar check API is a software service that allows you to provide suggestions for misspelled words and incorrect grammar natively in your app or on your website.

How does a spelling or grammar API work?

First, your program will make an HTTP request to the API service based on what a user types into a text area or other input field. Then, the API will deliver suggestions for correctly spelled words and grammar back to your program via JSON.

Who is a grammar or spell check API for?

These types of API are great for any app or website where correct spelling and grammar are important. They can be used on student-focused plagiarism checking software websites, blog hosting sites and anywhere else where users will want to make sure they have no grammatical errors or misspellings.

Why is a grammar check API important?

Using an API to check for grammar saves your users and your programmers a lot of work.

Your programming team no longer needs to build spelling and grammar checking functionality into your program, a process which can take a significant amount of work and distract from your app or website’s core elements. Additionally, using an API will allow your users to benefit from powerful and effective spell checkers and grammar correction functions.

What you can expect from grammar APIs and spell check APIs?

Today, most APIs that check grammar and spelling do so contextually, and with the aid of machine learning.

That means that, rather than simply looking words up in a dictionary, these APIs look at the words surrounding a typographical error in order to determine the most likely intended word.

For example, if a user types “I het ice ceam” instead of “I eat ice cream,” the API will flag “het” and “cream” as misspelled words, and will use the surrounding context to offer accurate suggestions.

Machine learning means that these tools also get smarter as more people use them to make corrections, so that an API can not only save you time, but can allow you to passively harness other applications’ userbase to improve your own service’s spelling and grammar checking functionality.

Many APIs, especially those with freemium or paid service models, can also check spelling and grammar in more than one language. However, there are also APIs which only check English, and these can be less complicated to implement.

Are there examples of free grammar check APIs or free spell check APIs?

There are a number of free APIs that check grammar and spelling, as well as some which offer freemium services.
