Free tools
Tools for the part of your website you cannot see.
Most website tools score what a page looks like to a person. These check what it looks like to a machine — a search crawler, an AI assistant, an agent trying to work out what your business does and whether it can quote you. We build them because we needed them on client work, and we publish them because a tool that only tells you what is wrong when you pay for it is not much of a tool.
Everything here is free, runs without an account, and does not ask for an email. We do not store the sites you check.

llms.txt generator + AI readiness check
Generates an llms.txt for your site, then does the part other generators skip: it reports which facts an answer engine cannot find — who owns the business, what it sells, what it costs, where it operates — because those gaps are what stop you being described accurately, file or no file.

Website & project cost calculator
Runs the same pricing model we use internally to scope real work, so the range it returns is the range we would start from. Asks about your business rather than about technology — you never have to guess whether you need Shopify, an API or a booking engine.

Guide
What kind of website does your business need?
The question the cost calculator assumes you have already answered. Twenty-four statements about your business, nine shapes a website can take, and an honest reading of which one your answers point at — including when the answer is "less than you were about to buy".

Guide
What technology should you build it on?
The decision after the one above. A five-level simplicity ladder, nine business situations, and a fifteen-criterion comparison of builders, Webflow, WordPress, Shopify and custom builds — written to stop you buying a level of machinery your requirements never asked for.

Guide
Do you actually need custom software?
The question that runs before all of the above. Buy, configure, integrate, extend or build — in that order, with the rule that you may only move down a rung by naming what the rung above could not do. Written by a studio that builds custom software, which is why it starts with the case against.

More tools will appear here as we build them. We would rather publish one that does something useful than five that generate files.
Implementation guides
How llms.txt actually works on specific platforms — verified against each platform's own documentation, with the version-specific behaviour that generic guides miss. Each carries the date its facts were last checked.
llms.txt on Shopify
Native since 28 May 2026. Every Shopify store serves /llms.txt, /llms-full.txt and /agents.md with no setup. /agents.md is the canonical agent-discovery document; /llms.txt mirrors it by default.

llms.txt on Next.js
No built-in llms.txt convention. Next.js has special metadata files for robots.txt and sitemap.xml, but llms.txt is not one of them — you implement it yourself, most cleanly as a Route Handler.

llms.txt on WordPress
No core WordPress support. Yoast SEO generates an llms.txt as a built-in feature you enable; dedicated plugins serve it via rewrite rules; or you upload a static file yourself. All three work — they fail differently.

Want the strategy behind the file?
Publishing an llms.txt is a small technical task. Being the business an assistant actually recommends is a different problem — one about entities, evidence and how your site states what it does.
