Terms of Use

Everything written on this site is free to read, with no account, subscription or paywall. The AI demos are free to use, subject to the daily limits in section 4.

The companion audiobook of the 13-part series “How to Architect an Enterprise AI System (And Why the Engineer Still Matters)” is sold on Gumroad, Google Play and Spotify. Those sales happen entirely on those platforms under their terms, their payment processing and their refund policies. I never see your card details, and this site processes no payments. Visual overviews are on YouTube at no charge.

This matters enough to state plainly rather than bury.

The substance is factual. The blog, the series and the audiobook come out of real situations: my own notes, my commits, my research, and systems I actually built. They are not fiction, and they are not invented case studies written to look like experience. What went wrong went wrong to me.

I write the drafts; AI tidies them. The reporting, the decisions and the conclusions are mine. A model cleans up grammar and phrasing, and renders my diagrams from the structure I describe. It is an editor and a draughtsman, not the author.

That still means a machine touched every page, so read figures the way I do — as something to check against the primary source, not as a citation.

The narration is synthetic. The audiobook and the per-post audio are produced with text-to-speech. It is not a recording of my voice. Nobody should mistake it for one, and it should not be used as a voice sample or as evidence that I said anything.

Every demo on this site sends your input to a language model or a scraping service and shows you what comes back. Those systems produce confident, fluent output that is sometimes simply incorrect. They invent citations, misread figures, and state things that are not so.

So, concretely:

• The research agent writes a draft from pages it fetched minutes earlier. It is labelled a draft because it is one. Nothing in it has been fact-checked by a person.
• The financial dashboard shows scraped market data and model-written commentary. It is not investment advice, not a quote you can trade on, and not a substitute for your broker or a licensed adviser.
• The vision and 3D demos describe and generate images from models that guess. A confident label can be wrong.
• Nothing here is professional advice — not financial, legal, medical, or engineering advice for your situation.

Use the demos to see how the systems are built. Do not act on their output without checking it against a source you trust.

The demos call paid APIs out of my own pocket, so there are daily limits per visitor and for the site as a whole. Reaching one produces a plain message saying so, not an error. Limits reset at midnight US Eastern.

Please do not:

• script or automate the demos, or run them in a loop
• work around the rate limits, including by rotating addresses
• use them as a free backend for something else you are building
• submit anything unlawful, or anyone else's personal information
• attempt to extract credentials, or probe the site for vulnerabilities without asking me first

On that last point: if you find a real security problem, I would genuinely rather hear about it. Email me and I will fix it and thank you.
