Bionic reading on a Mac — in every app, not just the browser
Bionic reading is a fixation technique: the first letters of every word are set in bold, your eye lands on that fixed anchor, and your brain completes the word without fully scanning it. The line rhythm stays intact, nothing moves, and the whole page remains readable — which is exactly why people who bounce off RSVP word-flashing often get on with it.
The problem with doing it on a Mac
Almost every bionic tool is a browser extension or a website you paste text into. That covers web pages and nothing else. On a Mac, a large share of serious reading happens outside the browser: a PDF in Preview, a contract in Word, a spec in Notes, an email in Mail, a changelog in a terminal. An extension cannot touch any of it, and pasting a confidential document into a website is not an option for most people who are paid to read.
How to get it system-wide
- Install QuickReadMac (macOS 13 or later, Apple silicon and Intel).
- Select text in any app and press ⌃⌘R. Or drop a PDF, Word file, ePub or Markdown file onto the reader.
- Choose Bionic in the mode picker. The text appears with the word-openings anchored in bold.
- Open settings (⌘,) and set fixation strength to Light, Medium or Strong — a live sample updates as you choose.
The emphasis is computed per word from its letter count, so short function words ("a", "of", "in") keep a single bold letter and never get shouted at you, trailing punctuation stays light, and no word is ever fully bolded — a fully bold word is no longer an anchor.
Combine it with the other modes
Bionic is a fourth mode alongside Focus (RSVP), Flow and Spotlight, and it composes with them: switch on “bionic emphasis in Flow & Spotlight” and the active-word tracking of those modes keeps working while every word carries its anchor. For dense reference material, Bionic on its own tends to win; for getting through volume, Focus at 400–600 WPM does.
Does bionic reading actually work?
Honest answer: the evidence is mixed. The independent studies that have looked at bolded word-openings have generally not found a reliable speed increase across all readers, and the technique's original marketing claims went well beyond what was demonstrated. What is well documented is that some readers — particularly people who lose their place, or who are reading in a second language — find the anchored line easier to stay on, and comfort is a real benefit even when the stopwatch doesn't move. Try it for a week on your own material and keep it only if it earns its place.
Privacy, since this is your reading
Everything happens on your Mac: the text you select, the PDFs you open, the reading history. No account, no upload, no telemetry — the app is signed with an Apple Developer ID and notarized, and it works with the Wi-Fi off.
Questions
Is there a bionic reading extension for Mac?
There are browser extensions, but they only work on web pages inside that browser. QuickReadMac applies the same fixation technique to your selection in any app, plus PDFs, Word files, ePub and Markdown, without a browser.
Can I change how much of each word is bolded?
Yes — Light (about a third of the word), Medium (about half) or Strong (about two thirds). A live sample in settings shows the difference before you commit.
Does it work offline?
Yes. Bionic mode, the RSVP reader, PDF parsing and the text-to-speech voices are all on-device. QuickReadMac only talks to the network to check for updates and to validate a licence key.
Is bionic reading good for ADHD?
Some readers with ADHD report that an anchored line is easier to stay on, and the app's Spotlight mode goes further by dimming everything except the words you're on. It is a reading aid, not a treatment, and we make no medical claims.
