I make things and give them away. There are no accounts here, nothing is for sale, and nothing asks for your email address.

Free English Books

I went from IELTS band 5.5 to band 8 over nineteen months. Afterwards I wrote down what had actually worked, as free exam preparation books — free to download, with no sign-up and no account.

Prompt Engineering Studio

A drag-and-drop editor for writing better instructions for AI models, assembled from labelled blocks — role, context, task, constraints, and the rest. It runs entirely in your browser, so what you write stays on your own machine.

Why it works this way

Every one of these started as something I needed and could not find for free, or could not find without handing over an email address first. Giving them away costs me hosting and a domain, which is a small price for work that was going to exist anyway.

None of it needs to know who you are, so none of it asks. The books download without an account. The studio keeps your work in your own browser and sends it nowhere. If something here saves you an afternoon, that is the whole of what it was for.

Written down

Building the studio taught me more about writing instructions for a model than using one ever did, so I wrote ten longer pieces about it — why an instruction gets ignored, how to stop a model inventing facts, choosing examples, when step-by-step reasoning is worth paying for, output a program can parse, one complete prompt taken apart line by line, what the Role block actually changes, what belongs in the system prompt and what in the user message, giving the model permission to say it does not know, and how I test a prompt before I change it.

Prompt engineering guides

Ten pieces on system prompts: what works, what is oversold, and the prompt text before and after. Free to read, nothing to sign up for.
