Investing research has never had a shortage of information. Filings, earnings calls, analyst notes, news, your own scattered notes.
The problem is time. Reading and organising all of it takes hours, and most self-directed investors have a job already.
First, the honest part. I’m not a financial adviser, and nothing here is investment advice. Investing involves risk, including loss of money. I build AI prompt systems, so for this guide I studied how self-directed investors do research, and where AI helps and where it fails. This post covers what I found.
What AI Can Do, and What It Can’t
Claude is good at language work. It can summarise a filing excerpt, build a comparison table from two sets of notes, explain a financial term at your level, and turn messy notes into a clean structure.
It cannot do four things:
- It has no live prices or account data, unless your setup gives it a specific tool.
- It does not know your financial situation, unless you describe it.
- It cannot predict the market. Anything that sounds like a prediction is a scenario, not a forecast.
- It can get numbers wrong. In the book’s words, the usual errors are a figure that is close but not exact, a detail from early in a long chat that gets misremembered, or a summary that fills a gap with a reasonable-sounding guess.
So the rule in the book is simple: the AI does the slow parts, you check the facts, and you make the decision.
Two Prompts That Argue Against You
Most of us look for reasons we are right. These two prompts do the opposite. Both are from the book (Chapter 8):
“Argue the strongest possible bear case against this company, based on the information I have given you.”
“What would need to happen for this thesis to be wrong?”
Notice the last part of the first prompt: “based on the information I have given you.” It keeps the AI to your notes, instead of guessing facts from memory. Whatever it writes, check each claim against a primary source before you rely on it.
A Safer Way to Ask
Weak question: “Is this a good stock?” That asks the AI for advice, and it cannot give you reliable advice.
Better, from Chapter 6: “Summarize what this company does in plain language, in under 150 words.” Then: “What information is this summary missing that I should look for separately?”
One task at a time. Facts first, opinions yours.
Where It Goes Wrong
The book lists common mistakes in every chapter. Three come up a lot:
- Asking for real-time prices when the AI has no access to them.
- Treating a scenario as a prediction.
- Skipping the check because the answer sounded confident and well organised.
The third one is the most dangerous. A confident, tidy answer feels trustworthy. That is exactly when to slow down.

How the Book Is Organised
The book has 4 parts, 16 chapters and around 190 copy-and-paste prompts:
- Part 1: Foundations and mindset. What Claude can and cannot do, responsible use, and how to avoid relying on it too much.
- Part 2: Seven core workflows. Market research and trend notes, company summaries and comparisons, portfolio and idea organisation, risk review and scenarios, learning financial concepts, buying and selling checklists, and watchlists.
- Part 3: Discipline and systems. Better prompts, avoiding overconfidence, keeping decisions verified, building a repeatable system, and 30-day and 90-day plans.
- Part 4: Bonus resources. A 30-day launch checklist, a prompt swipe file, a workflow blueprint with a worked example, a final 10-step roadmap and a glossary.
Who It Is For, and Who It Is Not
It is for self-directed investors who want a calmer, more organised research habit. That includes casual investors with small amounts. The book says the habits scale down just as well as they scale up.
It is not for anyone who wants stock picks or returns. There are none. The book says so on page one.
Check Everything
One prompt from Chapter 14 is worth saving today:
“List every specific figure or date in this summary so I can check each one against a primary source.”
Also, do not paste account numbers or personal financial details into a public AI tool.
