About This Site

MyAI is a personal technical notebook that turns what I learn in development, product planning and operations into structured, sourced learning documents.

How the documents are made

Written with AI tools. AI tools help with drafting, research and translation. This is stated openly.
Sources are kept. Facts that can change carry a date and a source, with links in each document's references.
Reviewed adversarially. A different model from the one that wrote a document reviews it by trying to disprove its scope, depth, examples and accuracy. Findings are fixed and the document is reviewed again.
Errors get fixed. If you find a mistake, tell me using the method on the contact page. I check it and correct the document.

Things to keep in mind

The documents are general learning material. The Business section in particular is not legal or tax advice, so confirm with the official authority or a professional before acting.
Tool features, prices and policies change often. Check each document's reference date and official sources.
External links open in a new tab. Linked sites are responsible for their own content.
