Read long articles with improved focus using a technique inspired by Bionic Reading. The tool applies a weight gradient across each word — the first letters are bolder, guiding your eyes and reducing re-reading. Fetch articles directly from a URL, paste HTML content from a website (formatting is preserved), or paste Markdown. Choose between three fonts optimized for reading (Inter, Literata, Lexend), and adjust the contrast intensity and offset of the weight effect to suit your reading style. Open the full-screen reader mode for a distraction-free experience. Tables and headings from the source are preserved. Particularly helpful for readers with ADHD, dyslexia, or anyone who struggles to maintain focus on long-form text.

If URL fetching fails, you can paste the text manually. It will keep a simplified version of the original formatting. Happy reading!
