About Us

Scroll Master is an interactive resource for learning new languages — vocab groups, flashcards, and a speed reader, all in one place.

We build on findings from eye-movement reading research — how the eye actually moves across a line, and how pacing and color affect fatigue and comprehension — to shape the experience: from the color combinations chosen to be easy on your eyes, to the careful tuning of reading speed. It’s not a Chinese-only tool; the same research-backed approach applies across every language on the site.

Currently covering Chinese, Spanish, English, and Japanese, with more languages on the way.

Learning Tools

We’re building a set of interactive tools to learn new languages, shaped by research on how people actually read:

  • Vocab Groups — browse vocabulary by category, with sub-group accordions and translation toggles; currently covering Chinese, Spanish, English, and Japanese, with more languages on the way
  • Flashcards — click-to-flip cards with native text-to-speech and example sentences
  • Speed Reader — a word-by-word RSVP reader with pacing and color palettes informed by eye-movement reading studies, plus tone-coloring for Chinese

More languages and features are on the way as the project grows.

Speed Reader

A word-by-word speed reader, built on eye-movement reading research rather than just a flashing-text gimmick — Optimal Recognition Point letter positioning, syllable-weighted pacing so a pause actually feels like a pause, and stage color combinations chosen to be easy on your eyes over a long session. Paste any text — or load a vocabulary list — and it flashes one chunk at a time, syncing native text-to-speech across Chinese, Spanish, English, and Japanese, with tone-coloring for Chinese: gold for 1st tone, red for 2nd, purple for 3rd, blue for 4th.
