Text and Grammar Checking API
Check text for grammar, spelling and style.
Features
Grammar checking
We use Artificial Intelligence to locate grammar mistakes that other checkers miss.
Contextual spelling
Typos are easy to make but can be hard to spot when they’re actually words. We look at the context to find them.
Terminology
Set up your own termbase and check for unwanted terms including different forms, capitalizations, etc.
Entity Spelling
Check for incorrect spelling of millions of people, places and things.
Writing Style
Automatically check for thousands of corrections that a human copyeditor would make.
Other
Want to go deeper? We check for many different writing-related issues such as poor readability, sentence variety issues, vague wording. We also include a contextual thesaurus. Anything in our app can be accessed through our API.
