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 →
Scores 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 →
Validates 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 →
Extracts every JSON-LD block, walks nested entities, and flags invalid JSON and missing required properties across 16 schema types.
Validate schema →
Fetches 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 →
Writes 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 →
Twelve checks on any URL: pixel-width titles, canonical tags, X-Robots headers, redirect chains, heading hierarchies, and sitemap inclusion.
Audit a page →
Crawls pages with navigation stripped to isolate editorial links. Identifies orphan pages and suggests high-relevance internal linking opportunities.
Map internal links →
Compares name, address and phone in your LocalBusiness schema against visible page text to prevent directory citation mismatches.
Check consistency →
We build a tool whenever client work or a research question demands it. Check our research programme to see what is currently in the lab.
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.
