Borderline visible. AI bots can crawl EPUB Viewer, 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 EPUB Viewer
from our crawl and measurement
EPUB Viewer is a business whose own site puts it this way: "A lightweight EPUB reader that supports notes, highlights, search, table of contents, night mode, split view and library sync." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.0 out of 10.
Our crawl found structured data on the page (SoftwareApplication) and a readable heading structure. It is missing an llms.txt file and a sitemap.
AI crawlers have visited 6 times in our tracking, including ClaudeBot (Anthropic), Applebot (Siri) and Meta AI.

What this score means
Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 4/10, EPUB Viewer is crawlable but under-signaled - fixable, and the signals above are where to start.
