Improved Spacing

Asymmetrica (Asym) is a patent-pending format for asymmetrically adjusting the spacing between words.

Easier Reading

This format builds visual cues into the text which improves your users' reading experience.

A Better Experience

Readers will be able to read faster, understand more, and remember your message better with Asym.


Asym is a software-based method that automatically applies this asymmetrical spacing to documents. It analyzes the organization of languages to determine how to best format word spaces to improve reading comprehension. Then it applies this analysis to modify the format of the spaces between words in real time to web or other documents.

Why do I need this?

The forty-three percent of adult Americans with low literacy have difficulty with moderately challenging literacy activities. All readers—but especially these struggling readers—will benefit from Asym and be able to read faster and understand more.

For publishers and advertisers, readers of your content, branding, and marketing creatives will also remember and engage with your message more with Asym applied. As an example, Asym Spacing has been shown to increase display advertising click-through rates by 15-33%, and up to 66% for well-targeted creatives.


Good readers have longer eye movements, shorter fixations (pauses during reading), and make fewer regressions (backtracking movements) than poor readers—a pattern which makes reading more efficient and more effective. Asym works by providing all readers visual cues within the text that subtly encourage the same eye movement patterns that good readers have learned to do naturally. These visual reminders help readers to pause and chunk phrases into units of meaning, as the brain would naturally pause during sentence comprehension.

This technique of emphasizing units of meaning with visual cues has been laboratory and field-tested by scientists in a variety of disciplines for over 60 years, and results have been published in dozens of peer-reviewed journal articles. These studies have demonstrated that manual and semi-automated application of this technique improves reading speed, comprehension, and enjoyment by up to 40%.

Our Technology
