What is Automated Readability Index (ARI)?
The Automated Readability Index is another readability test from our series of Readability Evaluators. It helps to translate readability into numbers.
ARI was published in 1967 by R. J. Senter and E. A. Smith. The formula was created for the U.S. Air Force Unit to evaluate the readability of documents on electrical typewriters in real-time. The authors found previous readability metrics (Flesch-Kincaid and Dale Chall) insufficient. They criticized the use of word lists (Dale Chall) for being a slow solution and syllable count (Flesch-Kincaid) for being inaccurate and unreliable.
How is ARI calculated?
4.71 x (characters/words) + 0.5 x (words/sentences) – 21.43
The result will be a score ranging from 1 to 14, where 1 is the easiest to read and 14 is the hardest. What exactly those numbers mean explains a table:
| Score | Age | Grade Level |
| 1 | 5-6 | Kindergarten |
| 2 | 6-7 | First Grade |
| 3 | 7-8 | Second Grade |
| 4 | 8-9 | Third Grade |
| 5 | 9-10 | Fourth Grade |
| 6 | 10-11 | Fifth Grade |
| 7 | 11-12 | Sixth Grade |
| 8 | 12-13 | Seventh Grade |
| 9 | 13-14 | Eighth Grade |
| 10 | 14-15 | Ninth Grade |
| 11 | 15-16 | Tenth Grade |
| 12 | 16-17 | Eleventh Grade |
| 13 | 17-18 | Twelfth Grade |
| 14 | 18-22 | College student |
You might want to make your article easier or more complex, depending on your audience.
Check out other metrics too
We also support metrics like Flesch-Kincaid, Dale Chall, Coleman Lieu, Gunning Fog, SMOG, Spache, and Linsear Write.
The last metric – Statistics gives you information about the number of sentences, words, and letters in your text.
FlowHunt can do much more, not just Readability
Create tools to your liking with the help of AI. Don’t worry, you don’t need to know any coding. It’s a drag-and-drop system where you drag your components from the sidebar and connect them to create a Flow. Such Flow transfers information from the Chat Input (text you send into the tool) through different components (Readability Evaluator is one such component) to evaluate, regenerate, or analyze how you need it.
The image shows the Dale Chall tool’s appearance (the Flow is the same for ARI, too).
But if you add LLM like ChatGPT, it gets slightly complicated.
If you use LLM you need to put a prompt into the Prompt component to make it work. The prompt for this tool is:
You are a skilled copywriter.
Your task is to evaluate readability of {input} .
If it is higher than 9 for ARI you need to improve it and return text with readability lower than 9.
If readability is lower than 9, return original text

You can even create a gigantic flow consisting of multiple smaller flows that execute in a specific order or an order AI deems necessary.
Don’t worry. If you find FlowHunt or Flows challenging, don’t hesitate to contact us. We’re always happy to help!
