Bolding the first few letters or every other word of a text is a technique some speed-reading methods use, based on the idea that the eye can pattern-match the rest of a familiar word once the emphasized part anchors recognition.
This tool bolds every Nth word throughout your pasted text (every 2nd, 3rd, or any interval you choose), creating a rhythmic visual pattern intended to help guide a faster reading pace through the passage.
Whether this specific technique meaningfully improves reading speed or comprehension is debated among reading researchers, but it remains a popular experimental approach some readers find helps them maintain pace and focus through longer passages.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.

Frequently asked questions
Does bolding every Nth word actually improve reading speed?
The effectiveness of this specific technique is debated in reading research — some readers find it helps maintain pace and focus, while for others it doesn't demonstrably change reading speed or comprehension.
What value of N works best?
There's no single correct value — every 2nd or 3rd word is commonly used as a starting point, though you might experiment with different intervals to see what feels most helpful for your own reading.
