About
A short course, written properly, that says only what it can source.
Lessons in Practice publishes one course: 28 lessons on working with Claude, ordered from a quiz and delivered a day at a time. This page is what we are, how it is built, and the rules we hold our own copy to.
What we are building
Microlearning that ends with something of yours.
Most self-directed learning about AI is a search result. You find a trick, it works once, and nothing accumulates. The course exists because a finish line and an order are the two things a pile of tips cannot give you.
So the shape is fixed: a lesson a day for 28 days, each one a single idea applied to material you already have, ending in week four with a small tool you built and a plan for what comes next. Every buyer gets all 28 lessons. The quiz changes the sequence, which is visible, and nothing else.
How the course is made
Written to a registry, not to a word count.
One registry, 28 rows
Every lesson exists as a row before it exists as a page: its slug, its week and day, its objectives, its estimated length, and what it is allowed to assume you have already read. The registry is what the plan screen reads, so the lesson list you see before paying is the real one.
Objectives before prose
A lesson carries two or three objectives and no more. The cap is the promise about its length: a lesson that needs a fourth objective is two lessons.
Your material, not a sample project
The worked example is ours. The thing you do afterwards is yours — your document, your inbox, your spreadsheet, your repository. A course you practise on a fictional company is a course you finish without having changed anything.
How we handle claims
Every number on this site has a row and a source.
We keep a claims register. It is a file in the repository, one row per assertion, and each row carries the exact wording, a source somebody else can re-check, whether a person actually opened it, and what the source does not establish.
Copy is written against the register rather than checked against it afterwards. A sentence carrying a figure, a superlative or a comparison is matched to a row at build time, and a page that fails is a page that does not deploy. When there is no row, the sentence loses the number rather than gaining a vaguer version of it.
That is why some things you would expect to see are missing here. Completion rates, outcome statistics and income figures need data we do not have, and we would rather have an empty slot than a comfortable one.

What we are not
The four sentences we will not write.
Not affiliated with Anthropic
We are not affiliated with, endorsed by, or sponsored by Anthropic. Claude and Claude Code are their products and their trademarks. We teach how to use them; we do not speak for them.
Not an accreditation
Finish at least 90% of the lessons and you get a certificate of completion of this course. It is not a qualification, it is not accredited, and it does not license you to do anything.
Not an income promise
We sell a course, not an outcome. We hold no data on what any student earned before or after taking it, so we make no claim about it, in either direction and in any wording.
Not urgent
There is no countdown on this page and no scarcity anywhere on it. The one timer in this product is anchored to a real server-recorded moment, it raises the price when it expires, and it does not reset when you reload.
Who it is for
People with a job to do and a Tuesday to get back.
The course is written for someone who already has the work — reports, meetings, research, spreadsheets, a codebase — and wants to move it rather than to study a new field. Week four is the exception and it says so: it installs a developer tool and asks for a change to a real file.

Start with the plan, not the payment.
The quiz builds your schedule and shows it to you first. Nothing is charged until you have seen what the 28 days look like.
