Welcome to the ProWritingAid API V2

The ProWritingAid grammar checker API allows you to check text for grammar mistakes, style improvements, and terminology mistakes as well as many other writing-related issues. All the reports used within ProWritingAid are available and you can combine all or parts of them as you wish.

Some examples of products that our API clients have built are:

• A tool to check medical transcripts for grammatical mistakes;
• A quality check for journal submissions;
• A tool to check student papers and provide feedback;
• A grammar checker integrated into a word processor;
• A CMS plugin to check submitted content articles for plagiarism and grammar;
• A plugin to a helpdesk chat system to check for Indianisms and other grammatical mistakes.

The easiest way to get started is by using one of our pre-built SDKs for:

• C#
• Javascript
• Typescript
• PHP
• Python
• Java

Some features of ProWritingAid's grammar checking API are:

• Contextual spellchecking finds a valid word in the wrong context, e.g. “This is gong to be awesome. You are a great fiend to me.”
• Terminology checking allows you to create your own Term Base and check text to make sure that it complies.
• AI-powered grammar checking finds complex mistakes that other checkers don't.
• Punctuation checking. Check for incorrect punctuation such as apostrophes, commas, and question marks.

If you want to check plain text then use our 'Text' method below. To get started you'll need to sign up for an API key.
