Crawler Detection Coverage
VigIA detects 55+ named AI crawlers in its tracker, making it one of the most comprehensive bot detection lists in the WordPress ecosystem. It also auto-detects noindex signals from Yoast, Rank Math, All in One SEO, SEOPress, The SEO Framework, and Native SEO NoIndexer, so pages marked as noindex are automatically excluded from AI visibility data.
LLMagnet also tracks AI bot visits by crawler type, with per-page breakdowns stored in your WordPress database. Both plugins store all data locally — no third-party infrastructure is involved.
Content Formats Served to AI
VigIA serves markdown endpoints for AI agents and implements the WordPress Abilities API — 9 discrete capabilities that let AI assistants like Claude or ChatGPT interact with your site’s analytics, blocking rules, and robots.txt management programmatically. This is a forward-looking feature for sites that want to enable agent-based interaction, not just passive indexing.
LLMagnet generates both llms.txt (the structured index) and llms-full.txt (complete page content for LLM consumption). Having both formats ensures compatibility with the widest range of AI crawlers, since some engines prefer the summarized index while others want the full content version.
WooCommerce Product Visibility
Both plugins handle WooCommerce, but with different approaches. VigIA includes WooCommerce product data in its markdown endpoints using YAML frontmatter fields: sku, product_type, price, regular_price, sale_price, currency, availability, stock_quantity, rating, and review data. LLMagnet includes product data in both llms.txt and llms-full.txt, making WooCommerce products crawlable in the standard AI file formats.
AI-Readiness Scoring
LLMagnet gives every page an individual AI-readiness score with specific recommendations for improvement — structured data coverage, content freshness signals, internal linking patterns, and metadata completeness. VigIA provides site-level visibility scoring. For publishers managing a large content library who want to prioritize which pages to optimize first, per-page scoring is the more actionable format.
The Abilities API Difference
VigIA’s implementation of the WordPress Abilities API is unique in this plugin category. It allows AI systems to actively query and manage your site’s AI visibility settings — blocking specific crawlers, retrieving analytics data, modifying robots.txt rules. For developers or power users building AI-native workflows, this is a significant capability that LLMagnet doesn’t yet replicate.
Documentation and Community
VigIA has a well-established developer community, particularly among Spanish-language WordPress users, and has earned 15 five-star reviews on WordPress.org. Its documentation at vigia.dev is detailed, including developer references for the Abilities API. LLMagnet has 5 five-star reviews and active development documented at llmagnet.com, with English-language support.
Who Should Use VigIA
VigIA is an excellent choice if you want maximum crawler detection breadth, the Abilities API for agent-native site management, granular bot blocking controls, and a plugin with a strong community track record (15 reviews). It’s particularly compelling for developers comfortable with technical configuration and sites that want to be at the frontier of AI-native WordPress infrastructure.
Who Should Use LLMagnet
LLMagnet is the better fit if you want the combination of llms.txt and llms-full.txt generation, per-page AI readiness scoring with actionable recommendations, and an English-language interface optimized for site owners who want a clear diagnosis of which specific pages need AI optimization work. The dual-file format (both llms.txt and llms-full.txt) ensures broader compatibility across AI crawlers.
The Bottom Line
VigIA and LLMagnet are the two most feature-complete free WordPress AI visibility plugins available. Neither is definitively superior — they have different strengths. VigIA wins on crawler detection breadth and the Abilities API. LLMagnet wins on the per-page readiness scoring workflow and llms-full.txt generation. Many sites would benefit from testing both and evaluating which dashboard gives them more actionable direction.
