Gold = selected letters already counted. Teal underline = words differing at the same recorded verse coordinate. This is a coordinate comparison, not a reconstruction of equivalent passages across segmentation systems. Empty cells mean that coordinate is absent.

What is being shown?

Each side contains the literal text in the supplied 28-letter Atlas. No spelling, letter, or whitespace normalization is performed by this viewer. The filename suffix is hidden in display labels only. All 160 challengers and all 114 suras are included.

Whole-sura totals count every selected letter in the chosen sura, subject to the verse-zero toggle. Animation counts only the displayed page. Whole-sura remainders are not page remainders. Pages contain up to eight shared verse coordinates.

Word differences use a longest-common-subsequence alignment within each shared verse coordinate. Repeated words can admit more than one equally valid alignment. Different segmentation can move otherwise identical words into different coordinates; highlighted words are not necessarily letter substitutions.

Opening-initial mode is available for all 29 initialed suras, counting each sura's own combined opening-letter set, including all five letters in Sura 42. For non-initialed suras, choose a letter or all 28 letters; no initial-family claim is made. Data is loaded one sura at a time from local files.
