What is the prevailing market narrative about growth?
The current trend is a continued AI buildout. Demand is still centered on chips, the power those data centers need, and the software around them. Interest rates are not the main constraint on that spending for now, because much of it is funded from the largest companies' own cash flow rather than from new borrowing.

Stock analysis

Open a company from Discover or your watchlist and read the price chart, the financial statements, and a short brief. Ask the chat about that name. The demo opens the companies in that sample book.

Portfolio tracker

Keep a book of what you own. See value over time and what the portfolio is made of, then open the workspace for holdings, a statement import, and chat about those names.

Demo Portfolio

A sample book of large US companies, with the same charts as a signed-in portfolio. Discover on that page is a short list of 30 names, and five of them sit on the watchlist. Chat works for one message, then create an account.

Earlier work

The book came first

Build Your Own AI Investor started as a book and a set of tools. This site is the portfolio app that followed.

  • Python, data science, and value investing, written for someone starting from zero.
  • Full video tutorials beside the chapters.
  • The same kind of fundamental tools this app uses now.
