No signup, no email capture, and no credit-card-required trial. Built to diagnostic standards, battle-tested across thousands of domains, and open to all.
Checks robots.txt against 14 AI crawlers from OpenAI, Anthropic, Perplexity, Google, Apple and Meta — and shows the exact rule behind every verdict.
Check crawler access → New 02Scores a live page on whether an AI can lift a clean answer from it. Nine weighted checks covering answer placement, structure, attribution and citations.
Score a page → New 03Validates your llms.txt against the spec, or builds a starter file from your sitemap. The file that tells AI assistants what your site actually contains.
Check or generate → New 04Extracts every JSON-LD block, walks nested entities, and flags invalid JSON and missing required properties across 16 schema types.
Validate schema → New 05Fetches alternate URLs live to verify return links exist — the reciprocity check most validators skip, and the one that decides whether Google honours your cluster.
Check hreflang → 06Writes metadata that fits Google’s pixel limits rather than its character guidelines. Live SERP preview shows where truncation lands.
Open generator →Finds keywords and groups them by search intent so you can map clusters before writing. The step that prevents keyword cannibalisation.
Open the tool → New 08Twelve checks on any URL: pixel-width titles, canonical tags, X-Robots headers, redirect chains, heading hierarchies, and sitemap inclusion.
Audit a page → New 09Crawls pages with navigation stripped to isolate editorial links. Identifies orphan pages and suggests high-relevance internal linking opportunities.
Map internal links → New 10Compares name, address and phone in your LocalBusiness schema against visible page text to prevent directory citation mismatches.

Open tool →Every one of these was built because we needed it for client work or for a study. Publishing them costs us nothing and gives you a way to check our reasoning against your own site before you ever speak to us.
If a tool tells you your site is fine and you do not need an agency, that is a correct answer and we are content for you to act on it.
The crawler checker generated our 506-domain study on AI crawler blocking. The extractability checker generated the 243-site study on whether AI can quote you.
A tool nobody has run at scale is an opinion with a form field. Ours have been run across thousands of real sites, and the raw data is published openly so you can check the output yourself.
If a tool surfaces technical debt or AI extraction blockers you would rather not fix yourself, that is what we are for.
