- Readability scores - including Flesch-Kincaid, Gunning Fog and the SMOG index
- Text analytics - text statistics (like letter, word and syllable counts), composition stats (like adjective, noun and adverb counts)
- Keyword densities - for single words, and two or three word phrases
- Reading and speaking time
- Sentiment analysis - is the text positive, negative or neutral

Readable.io Is Used By ...
Readability scoring originated as a tool for teachers to gauge whether a particular piece of text was appropriate for their class, and that is still as important as ever.
Our marketers are using Readable.io both to ensure their copy is easy to understand and quick to grab attention, but also to provide feedback on their marketing activities and demonstrate their value.
The legal profession is famous for overuse of technical terms and impenetrable text, but the lawyers using Readable.io are bucking that trend and ensuring what they write is easy for their audience to understand.
Accountants and other professionals, much like lawyers, rely on clear communication with current and prospective customers. Readability is key to that goal.
The medical profession has thoroughly embraced readability scoring and a huge amount of work is now going into checking that leaflets, instructions and studies are accessible and readable to a wide audience.
Every copywriter knows how to write good copy, but demonstrating that to a client can be a tough problem to solve. Copywriters use our tools to give an objective assessment of their work.
Not every author has easy access to an editor, and especially not throughout the writing process. But with our text tools, authors have access to a powerful set of editing tools whenever they need them.
And many more ...
Our customers cover hundreds more niches and use cases, in organisations of all shapes and sizes, even using us to compare hip-hop lyrics to those in rock and pop songs. If you're using Readable.io for something unusual, we'd love to hear about it!
What is a "Readability Score"?
A readability score is a computer-calculated index which can tell you roughly what level of education someone will need to be able to read a piece of text easily.
There are several algorithms available for measuring scores, and these use factors like sentence length, syllable count, percentage of multi-syllable words and so on to calculate their own readability score.
What's a Good Readability Score?
For grade levels, the result of most of the scoring algorithms, the score corresponds roughly to the number of years of education a person has had (based on the USA education system).
A grade level of around 10-12 is roughly the reading level on completion of high school. Text to be read by the general public should aim for a grade level of around 8.
Does This Only Work With English?
Several readability algorithms use syllable counting to determine their scores. The current syllable counter used here will only work with English text, so scores for other languages may be inaccurate.
The Coleman-Liau and Automated Readability Indexes do not use syllable counting, so should produce a reasonably accurate score in most European languages.
Languages like Arabic or Chinese, which reference words in different ways, will not score accurately due to inaccurate letter counting and sentence analysis.
What Algorithms Do You Use?
We provide scores based on the following algorithms (and we are always working on adding more to the list):
