Enter a reading focus state.
Papers, reports, textbooks. You need to absorb them, not skim.
Nook creates the focus state that gets you there.
You're not a bad reader. The environment is.
Sound familiar?
Closed after 2 min
You close it 3 minutes in
You open a 10-minute article with good intentions, but your focus fades before you're halfway through.
“What did I just read?”
You absorb nothing
You reach the end of a paragraph and realise you have no idea what it said. Your eyes moved, your brain didn't.
Focus over time
You can't sustain it
You read fine in short bursts but can't stay focused for longer than a few minutes. The stamina just isn't there.
Everything pulls you out
Every notification, every open tab, every stray thought pulls you away from the text. Getting back in takes minutes.
42 saved articles
The “read later” pile grows
You save articles with good intentions but never get back to them. The pile grows and the guilt compounds.

How Nook creates focus.
Six tools that quiet the noise
and keep you in the text.
Autopace
Text flows at your chosen speed so your eyes always have a guide. No scrolling, no searching — just reading.
One line at a time
keeps your focus
sharp and clear.
Line-by-line focus
Highlights one line at a time so your attention stays locked on exactly what you're reading.
Large walls of text are hard to track and easy to lose focus on. When you face a dense block of information, your brain naturally feels overwhelmed before you even begin reading.
Breaking content into bite-sized chunks improves comprehension significantly. By focusing on one piece at a time, you reduce cognitive load and absorb information more effectively.
Your brain processes information faster when it's not overwhelmed. This method keeps your momentum going, preventing the urge to skim or skip important details.
Paragraph chunking
Breaks walls of text into manageable pieces so dense material doesn't overwhelm you.
Bionic reading guides the eye through text.
Bionic reading
Highlights word beginnings so your brain recognizes words faster with less effort.

Reading-optimised fonts
Choose from 7 fonts including Lexend, Atkinson Hyperlegible, and OpenDyslexic.
Relax your eyes
Calm backgrounds
Reduce eye strain with softer colours. Sepia, dark mode, cream, and more.
Every feature is grounded in research
Peer-reviewed studies from Adobe Research, Brown University, Google, and more.
ACM CHI — Adobe Research & Brown University
2023
“Reading speed, comprehension, and preference all improved with digital reading rulers”
Readers with dyslexia saw the largest gains. Rulers reduced eye strain and fatigue.
Learning and Instruction
2024
“Guided reading fully closed the comprehension gap between ADHD and non-ADHD readers”
Stage-by-stage reading guidance eliminated performance differences entirely.
Journal of the International Neuropsychological Society
2025
“Guided word presentation boosted ADHD reading comprehension by removing eye-movement interference”
Eye movements themselves impair reading in ADHD — sequential presentation eliminates that barrier.
Learning and Individual Differences
2023
“Attention — not vocabulary, not memory — is the #1 predictor of reading comprehension in ADHD”
Tools that guide and sustain focus directly address the single biggest barrier.
RSVP Research — Meta-analysis
2023
“0% comprehension loss at up to 350 WPM with paced reading”
No significant difference vs. self-paced reading at moderate speeds.
Reading and Writing — Springer
2023
“Higher comprehension scores when text is shown sentence-by-sentence vs. full-page”
Segmented presentation outperformed traditional full-page layouts in young readers.
BMC Psychology — Springer
2023
“Segmented content significantly reduced cognitive load and improved comprehension + retention”
Also enhanced vocabulary acquisition across all test stages.
Journal of Educational Psychology
2024
“Structured reading breaks maintained comprehension — without them, it declined”
Trained readers held steady while the untrained control group got measurably worse over time.
Visible Language — Literature Review
2022
“Beyond 75 characters per line, readers lose track and perceive text as overwhelming”
Optimal reading range is 50–75 characters. Too-short lines also disrupt eye movement flow.
Psychonomic Bulletin & Review — Meta-analysis
2022
“Mind wandering negatively correlates with comprehension (r = −0.21) and worsens with age”
Breaking text into chunks creates natural re-engagement points that interrupt drift.
Cambridge Handbook of Multimedia Learning
3rd Ed.
“Deeper understanding when content is presented in manageable segments vs. continuous streams”
Mayer's Segmenting Principle — a foundational multimedia learning principle backed by decades of research.
Google Fonts — Lexend Research
2019
“20% faster reading speed with the Lexend font”
Designed by Dr. Bonnie Shaver-Troup to reduce visual crowding between letters.
PNAS — Zorzi, Barbiero & Facoetti
2012
“20% faster reading and 50% fewer errors with extra letter spacing for dyslexic readers”
Improvement equal to one full year of reading development. Replicated across two languages.
Anglia Ruskin University
2021
“13% faster reading speed for dyslexic children with wider letter spacing”
Also significantly reduced the number of words skipped while reading.
ACM Transactions on Computer-Human Interaction
2022
“35% reading speed difference between best and worst font — no single font suits everyone”
Different fonts suit different readers. Comprehension was unaffected by font choice.
TAY Journal — Karatay & Ünal
2023
“Improvement across all 4 measures with OpenDyslexic: speed, accuracy, prosody, comprehension”
Researchers recommended including OpenDyslexic in school textbooks.
Nature Communications — Pelli et al.
2025
“Visual crowding — letters too close together — is a neurological cause of reading slowness in dyslexia”
Crowding distance varies 2× between people and correlates with brain structure.
Frontiers in Language Sciences
2025
“Blue overlay filters reduced fixation time and increased reading speed in dyslexic children”
Eye-tracking confirmed shorter fixations and longer saccades vs. no filter.
Ophthalmic & Physiological Optics — Wilkins
2002
“25% faster reading with a colored overlay for children with visual stress”
About 5% of mainstream students show this benefit. Not attributable to placebo.
Education and Information Technologies — Meta-analysis
2026
“Screen reading lags print by 0.48 SD — but the gap drops to just 0.03 SD without scrolling”
Controlling text presentation nearly eliminates the digital reading disadvantage.

Questions about focused reading
Everything you need to know
Focused reading is a state of deep engagement where you read without losing your place, re-reading sentences, or drifting off. Nook creates this state using autopace, text chunking, bionic text, and distraction-free environments — so you can read longer and absorb more.
Nook guides your reading with autopace (text moves at your speed), chunking (breaks text into manageable pieces), and bionic formatting (highlights word beginnings). Combined with calm backgrounds and clean fonts, these tools eliminate the friction that causes your mind to wander.
