Bionic reading is an experiment in formatting prose so that the first portion of each word is visually emphasised. The eye lands on the bolded part first, and the brain fills in the rest of the word from the visual sketch — which, the theory goes, reduces the cognitive load of decoding the whole word letter-by-letter.

Some readers swear by it for plowing through dense text. Others find it distracting. The honest answer is "it varies" — if it helps you, use it. If it doesn't, this is two seconds of clicking away from regular paragraphs.
Is it backed by research? The honest answer is mixed. The 2022 viral take that Bionic Reading was a "breakthrough" was largely marketing. Independent studies since have found little measurable speed gain on average, though some readers — especially those with ADHD or who are already skim-reading dense text — do report it helps. If it clicks for you, use it. If it doesn't, the regular paragraph is two clicks away.
