Biohacking platform · bionic reading chrome extension
OptiBio is a biohacking platform — tools built to work with your biology, not against it. Our first product, OptiBio Read, applies bionic reading to any webpage: bold fixation, focus mode, comfort tint, and dyslexia-friendly font. Private. On-device.
Bionic Reading works by bolding the first part of each word. Your brain recognizes words by their shape and context, not every single letter on the page.
OptiBio is building a platform where every tool is designed around how your body and brain actually work — reading today, more optimizations tomorrow.
Bionic reading on every website. Fixation guides, focus mode, comfort tint, dyslexia-friendly font.

Most people quit too early. OptiBio Read guides you through the biological adaptation phase.
Install OptiBio Read, click the icon on any article, and bionic reading applies instantly. Toggle with Ctrl+Shift+Y. No account.
Five levels from F1 (light) to F5 (heavy). Start at F3, read for five minutes, then adjust until text feels guided — not interrupted.
Discomfort is normal at first. Our adaptation tracker guides you through the 15–30 minute window when your brain rewires for faster screen reading.

Get OptiBio Read — $2 lifetimeFixation determines how many leading letters are bolded. OptiBio Read gives you F1 through F5 — adjust in real time from the popup.
Navigation bars, sidebars, and footers fade to 35% opacity. Your article stays sharp. Built for the kind of deep skimming Bionic Reading was designed for.
Reading is biological — lighting, spacing, and font shape all matter. Dial in a warm or sepia tint, narrow the reading column, loosen line height, or switch to Lexend for easier letter discrimination.
Per-domain overrides let you choose exactly where Bionic Reading applies. Enable, disable, or blacklist any site from the settings page.
Better reading.
Less effort.
Fixation reading is not magic — it works when you use the right tool, adjust the right setting, and give your brain time to adapt. OptiBio Read handles all three.
The guide most extensions skip — and the reason most people think Bionic Reading does not work.
Read for five minutes at the default fixation. If text feels cluttered, go lighter. If you barely notice a difference, go heavier.
Long articles, research papers, screen reading when tired. Not novels, proofreading, or tweets.
Your brain needs time to build new reading pathways. After 15–30 minutes, standard text may start to feel slow by comparison.
7-day free trial. Early bird is $2 lifetime for the first 100 users, then $20 lifetime.

Fixation reading bolds the first part of each word. Your brain recognizes words by shape and context — the bold letters create visual anchors that guide your eyes across the page faster.
Your brain has years of pathways for standard text. Fixation reading asks it to use a different one. That transition feels uncomfortable at first. After 15–30 minutes, most readers report the discomfort fades and reading speed improves.
