Bold-First Reader
Reformat any text so each word leads with bold letters and trails off — a lead-bold reading format some readers find easier to track. Adjust how much of each word is bold, how much the rest dims, and export as rich text, HTML, or Markdown.

Format
Fixation fixes the leading part of each word: ceil(word length × ratio) letters are bolded. Presets and the slider set the same value. Words shorter than the minimum are left untouched.
- Contractions bold as one unit up to the apostrophe: don’t, can’t.
- Hyphenated words apply the fixation rule to the first segment only: well-known at 50%.
- Single-letter words that pass the minimum are fully bolded.

What the evidence says: reading-speed gains from this kind of lead-bold formatting are not established — controlled studies have generally found no significant general speedup, while some readers (including some dyslexic and ADHD readers) report improved focus. Treat it as a reading-format option, not a treatment.
