Text Formatting

Bold the first half of each word to try a different reading layout. Export the formatted passage as HTML for a compatible editor.

How to use

Paste the passage and inspect the generated markup. Copy the HTML into an editor that accepts HTML rather than a plain text field.

Example

The word reading is shown with read in bold and ing in regular text. Punctuation stays outside the bold section.

FAQ

Does this improve reading speed?

The tool changes appearance only. Compare it with your usual layout and keep the version that is easier for you to read.

A practical task

Test the same paragraph in ordinary and emphasized form. Keep the content, size, and line length constant so the comparison concerns the emphasis alone. The output is HTML, so plain text fields show tags instead of a reading layout.

Another useful question

Does emphasis change the underlying words?

It adds bold markup around word starts. Copy the original when you need unformatted text, and review the rendered version with your own reading preferences.

Details for interpreting the result

Detail Explanation
Readability formulas Readability formulas use measurable features such as sentence length and estimated syllables. They do not understand accuracy, organization, relevance, or prior knowledge. A useful technical term can lower a score without making the sentence wrong.
Rate based estimates An estimated duration divides an amount of text by an assumed rate. It does not observe a real reader or speaker. Change the assumption when the audience, technical density, or delivery style changes.
Words and tokens A word count depends on token rules. Punctuation, apostrophes, digits, and languages without spaces create edge cases. Use the receiving editor's definition when a formal limit must match its own counter exactly.
Context and audience The same fact needs different explanation for a specialist and a first time reader. State the audience, purpose, and terms they already know. Relevant context guides wording more effectively than broad requests to make a text impressive.
Words and meaning Sharing words does not prove that two passages make the same claim. Negation, order, context, and different subjects can change meaning while vocabulary stays similar. Read the passages before making an editorial judgment.
Paragraphs and lines A manual line break and a paragraph boundary serve different purposes. Export tools can map them differently. Inspect lists, addresses, and intentional blank lines rather than treating every visible break as interchangeable.
Font coverage A font contains only the glyphs it supports. A Unicode character in the source does not guarantee that every export font can draw it. Inspect accented names, non Latin text, and emoji in the final document.
