Borderline visible. AI bots can crawl Codex Sinaiticus, but the structured-data signals are thin - you are at real risk of being skipped when buyers ask ChatGPT, Claude, or Perplexity for a recommendation.

About Codex Sinaiticus
from our crawl and measurement
"Codex Sinaiticus is one of the most important books in the world. Handwritten well over 1600 years ago, the manuscript contains the Christian Bible in Greek, including the oldest complete." That is how Codex Sinaiticus introduces itself. As far as answer engines are concerned it may as well not exist yet: 2.2 out of 10.
Our crawl found a readable heading structure. It is missing structured data describing the business, an llms.txt file and a sitemap.

At 3.2/10, Codex Sinaiticus is crawlable but under-signaled - fixable, and the signals above are where to start.
