Bionic preview
This is not the same as speed reading. The technique was developed by Swiss typographic designer Renato Casutt in 2016 and has been popularized by various reading apps. Studies on its effectiveness are mixed — some people find it helpful, others see no benefit. Try it for yourself with any text below.
💡 Bionic reading guides your eyes through text by bolding the first part of each word — the brain fills in the rest from the bolded letters. Effectiveness varies: some readers find it speeds them up, others see no difference. Try different fixation amounts to find what works for you.
Email tips
For dense corporate emails or industry newsletters, bionic format speeds up the "should I read this carefully?" decision.
Lower fixation (30-40%) works well for casual scanning — high enough to guide, low enough not to disrupt natural reading.
