Check link previews in 12 apps, AI visibility for ChatGPT, Claude, Perplexity, and app links.
Scored across 5 tools
Each tool targets a distinct check domain: AI crawler access, mobile app links, social link previews, and performance, with check_url acting as an explicitly documented umbrella. The descriptions go out of their way to say when to use check_url versus the focused tools, so an agent can route reliably.
All five tools follow a uniform check_<subject> snake_case pattern (check_ai_visibility, check_app_links, check_link_preview, check_performance, check_url). No camelCase or vague verbs anywhere.
Five tools is exactly right for a URL audit service: four focused checks covering the core dimensions of link health plus one aggregator. Nothing looks padded or redundant.
The surface covers the domain's main diagnostic areas and the umbrella tool prevents dead ends when a user just says 'check my link'. Minor gaps remain: no batch/multi-URL checking, no scheduled re-check or history, and no follow-up action beyond copy-ready fixes returned in results.
Check whether ChatGPT, Claude, Perplexity and other AI search tools and assistants can reach, read and cite a URL. Evaluates robots.txt for each AI bot, requests the page with each bot’s User-Agent to catch CDN or firewall blocks, checks noindex, and shows the text an AI crawler gets from the raw HTML without JavaScript. Returns a score, per-bot access and copy-ready fixes. Use it for questions like "can ChatGPT see my site" or "why doesn’t Perplexity cite my page".
Inputs: url (required).
Check whether a URL opens the site’s iOS or Android app instead of the browser. Validates apple-app-site-association (iOS Universal Links) and assetlinks.json (Android App Links), tests this exact URL against the iOS path rules, and compares the files with the copies Apple’s CDN and Google’s Digital Asset Links service have cached. Returns status per platform and copy-ready fixes. Use it when Universal Links or App Links do not work.
Inputs: url (required).
Check how a URL’s link preview (title, description, image) appears when shared on WhatsApp, Facebook, Messenger, Instagram, X (Twitter), LinkedIn, Telegram, iMessage, Discord, Slack, Snapchat and TikTok. Fetches the page as each app’s crawler, validates Open Graph and Twitter Card tags and the preview image (size, format, weight), and returns a score, per-app results and copy-ready fixes. Use it when a shared link shows no preview, the wrong image or title, or before sharing a page.
Inputs: url (required), crawler.
Check what slows a URL down, without running a browser. Times the server response as a regular browser (time to first byte, compression, caching, redirects, HTTP/3), reads the HTML for render-blocking scripts and stylesheets, third-party scripts, the main image (lazy loading, preload, weight), images without width and height, and font loading, and reports real-user Core Web Vitals (LCP, INP, CLS) on phones from the Chrome UX Report when Google has data. Returns a score and copy-ready fixes. Use it for questions like "why is my site slow" or "how do I improve my Core Web Vitals".
Inputs: url (required).
Run every Sharelint check on a URL at once: link previews in 12 apps, AI visibility for ChatGPT, Claude and Perplexity, iOS and Android app links, and performance. Use it for a general "check my website or link" request; use the focused tools when the question is about one of these.
Inputs: url (required), crawler.
