Why long articles feel impossible
The problem isn't your attention span.
It's how text is presented.
Walls of text overwhelm
Dense paragraphs feel like a chore before you even start. Your brain wants to skim or skip entirely.
How chunking fixes this →Important context here
More key information
You only read this line
Missed this too
And this detail
You start skimming
Your eyes jump around, skipping lines and missing important details. Comprehension suffers.
Same paragraph, third time
Re-reading the same line
Your mind wanders, and you realize you didn't absorb anything. So you start again. And again.
Why this happens →"Where do I even start?"
Overwhelm before you begin
Just looking at the article triggers avoidance. You save it "for later" and never come back.
Brain fog after 5 minutes
Mental fatigue sets in fast
Your brain is constantly filtering surrounding text. Even short articles leave you drained.

Questions about chunking
Everything you need to know about text chunking
Chunking is a reading strategy that breaks large blocks of text into smaller, more manageable pieces. Instead of facing an overwhelming wall of text, you focus on one paragraph or line at a time. This reduces cognitive load and helps your brain process information more effectively.
Yes! Chunking is particularly effective for ADHD readers. Large walls of text can trigger overwhelm and avoidance. By showing only one piece at a time, chunking removes the 'where do I even start?' feeling and keeps you focused on just the current segment. Many ADHD readers report it's the feature that finally helped them finish articles.
Paragraph chunking shows one paragraph at a time - great for general reading and articles. Line chunking shows just one line at a time - perfect for dense technical content, when you're highly distracted, or when you tend to skip lines. You can switch between modes anytime based on what you're reading.
Absolutely. Chunking works beautifully with autopace (automatic scrolling), bionic reading (word highlighting), and custom fonts/backgrounds. Many users find the combination of chunking + autopace particularly powerful - chunking breaks up the text while autopace keeps you moving forward.
Yes. Chunking works on web articles, PDFs, and EPUB books. Nook automatically detects paragraph breaks and applies chunking consistently across all your reading material.
Yes! You get 3 days of full access to every feature including both chunking modes - unlimited articles, books, and PDFs. No credit card required.
