Weak AI visibility with 7 of 22 criteria passing. Biggest gap: llms.txt file.
Verdict
letter.ai is early-stage for AEO readiness, with an overall score of 33/100 and multiple foundational gaps that limit machine interpretation. Critical discovery and indexing signals are missing, including `llms.txt` (0), schema coverage depth (0), and RSS/Atom feed (0). Content quantity is strong in places, with 29 quantitative data points (fact density score: 8) and 59 internal links (internal linking score: 7), but extractability and trust signals are weakened by missing structured data, no explicit freshness metadata, and weak entity reinforcement. In short, the site has usable content volume but lacks the technical packaging AI systems rely on for confident retrieval and citation.

Tidio has a 251-line llms.txt. Crisp has zero. The score gap: +29 points. This single file tells AI assistants exactly what your site does -and without it, they're guessing.
Tidio runs 4 JSON-LD schema types. Crisp runs zero. That's not a coincidence -it's the difference between a 63 and a 34. Structured data is the machine-readable layer AI trusts most.
Sitemaps tell crawlers what exists. RSS feeds tell them what changed. If you don't have one, your new content waits days -or weeks -to be discovered.
Your sitemap says 500 pages exist. Our crawl finds 700. Those 200 missing URLs? AI crawlers will never know they exist.
