Instantly see how AI assistants — ChatGPT, Claude, Gemini, and Perplexity — discover, perceive, and cite your website. Free Chrome extension. No signup. No tracking.
In 2025, ChatGPT, Claude, Gemini, and Perplexity collectively answer more than a billion business-related queries every month. When a user asks «best web designer in Tel Aviv» or «who delivers organic produce in Brooklyn», AI assistants no longer link to a page — they synthesize an answer and cite a few sources. If your site is not in that citation set, you don't exist for that user.
AI visibility is the new SEO. Unlike traditional search-engine optimization — links, keywords, page speed —
AI optimization is about structured signals: JSON-LD markup, llms.txt manifests, robots.txt rules
for AI crawlers, and explicit business profiles. These signals are mostly invisible to a human visitor, but they are everything
for an AI assistant deciding whether to cite you.
Sofair Scanner is the first Chrome extension purpose-built to diagnose those signals. One click on any site, and you see exactly what AI assistants see — and what's missing.
Sofair Scanner runs entirely on click. There is no background activity, no automatic scanning, no data sent before you initiate.
Open any public site in Chrome. Click the Sofair Scanner toolbar icon. The extension activates only on this tab, only for this scan.
JSON-LD / Schema.org markup, /llms.txt manifest, /robots.txt rules for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, /ai-info.json, /sitemap.xml, meta tags. All reads happen from your browser to the site's own server.
A citation-fitness score, 4 category breakdowns, and concrete actionable recommendations. If the site is in Sofair Index, you also see Content Freshness and Category Benchmark.
Every Sofair Scanner scan breaks your site's AI-readiness into four orthogonal categories. Two run locally on any site; two require the domain to be indexed in Sofair.
JSON-LD blocks parsed from the page DOM. We check for valuable Schema.org types: Organization, LocalBusiness, Article, Product, Service, FAQPage, BreadcrumbList. Each present type increases the structured-data sub-score.
The /llms.txt manifest, /ai-info.json business profile, /sitemap.xml index, meta description, OpenGraph tags. Plus robots.txt rules for the four major AI crawlers: GPTBot, ClaudeBot, PerplexityBot, Google-Extended.
For sites already in the Sofair Index — how recently has our crawler re-scanned your content? Fresh content ranks higher in real-time AI retrieval. Stale content gets superseded.
For indexed sites — how does your AI-discovery score compare to peer sites in the same business category? Sofair Index groups sites by activity vertical and computes percentile rank.
Traditional SEO is about pleasing Google's search algorithm: links, keywords, page speed, mobile-friendliness. AI SEO is about pleasing the LLMs that increasingly intermediate between users and the open web.
llms.txt manifest — a Markdown file at site root that says «here's what this site is about and which pages matter». Increasingly fetched by major AI vendors.ai-info.json business profile — explicit business data in JSON. Sofair Index uses it for indexed sites.robots.txt for AI crawlers — GPTBot, ClaudeBot, PerplexityBot, Google-Extended all honor the classic protocol. Block them and you opt out of AI visibility.Use both. Traditional SEO tools (Ahrefs, Semrush, Moz) for Google rankings. Sofair Scanner for AI-assistant citation. The signals overlap partially, but the priorities differ.
Six personas, one extension. Every persona has a slightly different reason — but all benefit from making AI visibility measurable.
Pre-launch a new marketing site, scan it with Sofair Scanner, fix the gaps before customers arrive. AI visibility from day one.
Your client is paying for traditional SEO. Add Sofair Scanner output to the quarterly report. Quantify the AI-discovery delta vs competitors.
Open competitor sites, click the icon, compare scores. The Category Benchmark category shows where each site ranks among peers in the same vertical.
Implementing JSON-LD or llms.txt? Sofair Scanner verifies that the parsing works end-to-end, with exact diagnostic messages for missing types.
You publish 20 articles a week. Spot-check whether they're discoverable: JSON-LD Article types, llms.txt references, robots.txt rules for AI crawlers.
Differentiate from traditional SEO shops. Run Sofair Scanner during client onboarding. Sell setup and ongoing AI-visibility monitoring.
Each AI assistant runs its own crawler with a distinct User-Agent string. Sofair Scanner checks the robots.txt rules for all four — block any and you lose the corresponding AI's citation channel.
Sofair Scanner is built to do one thing and one thing only — diagnose AI visibility on a single tab when you click the icon. Everything else is explicitly off.

AI visibility is how well your website is understood and cited by AI assistants (ChatGPT, Claude, Gemini, Perplexity) when users ask them questions related to your content. Unlike traditional SEO — which targets search engines — AI visibility targets the AI-generated answer layer that's increasingly replacing search.
AI discovery is the upstream process — how AI crawlers find, parse, and index your site. AI visibility is the downstream outcome — how well your site shows up in AI-generated answers. Sofair Scanner measures discovery signals to predict visibility.
