# AI Sightable > AI Sightable is a WordPress plugin that scores whether AI assistants (ChatGPT, Claude, Perplexity, Google AI Overviews) can find, quote and cite each page of a site, logs verified AI crawler visits, and fixes what holds pages back. The core plugin is free on unlimited sites; optional Pro credit packs pay for AI-written fixes. ## Key facts - Free forever: 8-module AI readiness score, full-site scan, AI crawler log with reverse-DNS verification (16 bots), per-crawler robots.txt control, llms.txt, structured data that merges with Yoast, Rank Math, AIOSEO and SEOPress. Runs on the site's own server and sends no data anywhere. - Pro (credits): AI deep diagnosis, AI FAQ section, answer-first opening rewrite, AI title and meta description. 1 credit per action; fully optimizing a page takes 4 credits. - Pricing (USD, one-time, credits never expire, shared across all sites): Starter $9 for 100 credits (about 25 fully optimized pages); Growth $39 for 500 credits (about 125 pages); Scale $129 for 2,000 credits (about 500 pages). New accounts get 20 free credits. - AI Citation Monitor (separate monthly subscription, not part of Pro credits): every week asks ChatGPT, Perplexity and Gemini the questions customers ask and charts whether answers mention or link to the site. $19/month for 10 questions, $49/month for 30, $129/month for 100; cancel anytime; one free check of up to 5 questions. - 100 credits = fully optimize 25 pages, or new SEO titles and meta for 100 posts, or diagnose 50 pages and add an FAQ to each. - Requirements: WordPress 6.5+, PHP 8.1+. Licence: GPL v2 or later. - Privacy: Pro sends only the single page the user runs an AI action on. Unchanged re-runs are free; failed runs are refunded. ## Pages - [Home](https://sightable.io/): what the plugin does, Free vs Pro comparison, FAQ - [Pricing](https://sightable.io/pricing.php): credit packs, what credits buy, AI Citation Monitor monthly plans, billing FAQ - [Documentation](https://sightable.io/docs.php): setup, readiness score, crawlers, llms.txt and schema, fixes and undo, connecting Pro, credits - [Download](https://sightable.io/download.php): free plugin zip and install steps - [Contact](https://sightable.io/contact.php): contact form for support, sales and partnerships - [Privacy](https://sightable.io/privacy.php) and [Terms](https://sightable.io/terms.php) ## Contact - support@sightable.io
