Bionic Reading Converter

A reading technique that bolds the first part of each word to help your brain scan text faster.

Bionic Reading Converter completes this text task in seconds, without the manual back-and-forth. With Bionic Reading Converter, this kind of text edit becomes as simple as copy and paste. The whole process happens locally in your browser; nothing is sent to a server.

Step-by-step

Paste what you want to read into the Your text field: an article, lecture notes, a long email.
Set Bold intensity % (20-70) to control how much of each word is bolded. Low values highlight only the first letter or two, high values cover more than half the word.
Click Run and start reading the converted text in the result area.
If your eyes tire or your focus drifts after a few paragraphs, change the percentage and run it again.

Example

A student going over long notes during exam week converts the same page at 30 percent, then at 50 percent. At 30 the text stays close to normal and is easy on the eyes. At 50 the word openings stand out much more, but some short words end up almost fully bold and the page starts to look busy. A couple of tries is usually enough to find a comfortable range. There's no correct setting. The point is finding whatever helps you stay focused through a long text.

When is it useful?

Worth a try if you lose your place or drift off while reading long passages on screen. Some readers say bolded word starts help them skim more smoothly, others notice no difference at all. Treat it as a way to test your own reading habits, not as a guaranteed speed-reading method.

How does it work?

The tool splits the text into words at whitespace and bolds the first part of each word. The bold part is the percentage you choose of the word's length (at least 1 letter). The percentage is limited to 20-70, 40 is used if you leave it empty, and 10 is raised to 20. Example (40%): “Okuma hızını artırmak için” → “Ok uma hı zını art ırmak iç in”, with “Ok”, “hı”, “art” and “iç” in bold. The result is shown on the page as formatted text.

When using it

The percentage applies to all characters of the word; punctuation counts toward the length. In “merhaba,” the comma is counted too.
Every whitespace-separated piece counts as a word; in short words only the first letter is bold.
This is an aid to try, not a proven reading-speed booster; some people find it comfortable and others find it distracting. Try it for yourself.
Bold formatting may not survive copying into another app; check the result there for an important document.

Things to keep in mind

Research on whether this technique improves reading speed or comprehension is inconclusive. Your own experience is the best guide.
Bold is formatting. If you paste the result somewhere that only accepts plain text, the emphasis may disappear.
For reading difficulties such as dyslexia, this tool is not a substitute for proper support. Talk to a specialist if you need help.
Bolding word starts in code, formulas or tables can make them harder to read. Leave those parts unconverted.
