Our scores are backed up by established readability algorithms and verified by over 10,000 automated tests and hand-calculated scores. You can be confident in your results.

Exquisite Support

We're here to help if you need us, with an extensive knowledgebase as well as in-app and email support.

Who Is Readable For?

Readable is for anyone who writes, but these are some of the people we help most often.

Web Marketers

If you work in web marketing, you know that success is down to a dazzling array of factors. But Content Is King. And Readable can make sure that, whatever the search algorithms do tomorrow, no hard-won reader is turned away by impenetrable text.


Every author is different, with their own way of working. Readable gets out of your way, offering you as much support as you need, when you want it.


Readable was born out of a need for software to analyse reading materials for students, and it is still used for that today. Whether you're looking to give students feedback on their work, or to see if a particular piece is suitable for a particular audience, Readable can help.


For insurance companies, great readability of contracts and other written materials is more than just a nice feature, it's often (depending on where you are) a legal requirement.

Medical Companies

It's critical for any medical company to ensure all of their written materials avoid jargon or complex language, especially when it comes to leaflets and instructions distributed with medical products.


National and local governments product a huge amount of content for a vast audience with a broad spectrum of reading ability, and Readable can help ensure that all of that content is as accessible to that audience as possible.

My clients support vulnerable people; plain language is essential when writing for these audiences. Readable makes it easy to show clients when their copy isn’t using plain language.
