How it works
From a ticker to a sourced analysis
What you get
What every report gives you
Value and quality analysis
We look at the company's financial quality, its profitability, its competitive advantage and how it allocates capital.
- Competitive advantage and earnings quality
- Profitability and cash flows
- Capital allocation and debt sustainability
Institutional positions and insider moves
See how institutional investors and the company's own executives are positioned, from their official filings.
- Institutional positions from 13F filings
- Purchases and sales by the company's executives
- The most recent regulatory filings
Devil's Advocate AI
We do not only look at the case for a stock. We actively search for the risks, the weak assumptions and the events that would break the thesis.
- Finds the main risks and weak assumptions
- Looks for what could go wrong
- Sets out the case for and against
Ask the AI
The report is the start of the conversation, not the end of it.
- Ask anything about the analysis you just got
- Request comparisons with other stocks
- Dig deeper into the risks and the points that matter
The difference
A convincing answer, or analysis you can verify?
Ask:How much debt does the company carry, and is it manageable?
A general chatbot
It can give you a convincing answer, but it's not always clear which financial figures the numbers come from, or how recent they are.
- You don't know which financial period it refers to.
- It may rely on older figures.
- It's produced by the model, not the company's actual figures.
Ploutos
You get the actual net debt from the latest official filing, together with:
- the most recent figures, straight from the filings (not last year's)
- an analysis of whether it's manageable against earnings and cash flow
- and the opposing view with the key risks
At Ploutos the numbers come from the company's most recent official SEC filings, not from a model's memory.
Who it's for
For anyone who picks their own stocks and wants to understand what they're buying, with data instead of tips.
Who it's not for
It doesn't hand you 'sure things', it isn't for day-trading, and it won't tell you what to buy. If you want someone to decide for you, this isn't it.

What is Ploutos AI?
A research tool for US stocks and ETFs, assisted by AI.
You enter a ticker and within minutes get a structured report with fundamentals, institutional positions and risks. It does not tell you what to buy. It helps you understand what you are buying.
How does it use SEC data?
Financial statements, institutional positions (13F), executives' purchases and sales and ETF holdings come from the filings companies and funds make with the SEC.
The AI analyses and explains that data; it does not invent it. Every key number carries its source and date, so you can check it yourself. More in the methodology.
Which stocks and ETFs does it cover?
Those trading on NYSE, NASDAQ and NYSE American: US companies, and foreign ones listed in the US.
ETFs get their own analysis: what the fund holds from its SEC filings, how good its companies are, which sectors it is in, how it compares with the S&P 500, what changed in its holdings, how much money flows in or out and what it costs.
How is it different from a general AI chatbot?
A general chatbot gives answers that sound convincing without always showing where the numbers come from or how recent they are. It may, for example, give you last year's earnings as if they were current.
At Ploutos the numbers come from the most recent SEC filings, and the devil's advocate actively looks for what could go wrong.
How much does it cost?
There is a free plan with no card, with one analysis a month, and paid plans for more, or analyses paid once without a subscription. All give the same analysis, from the same data.
The data pages (company pages, ETF overlap, portfolio x-ray, dividends, bond ETFs, DCF calculator) are free and need no account; on the company pages, the last three fiscal years are open to everyone, five with a free account, and the full history and the Excel file come with Ploutos Investor. See the plans.
Is Ploutos AI investment advice?
No.
Ploutos AI provides research and information for educational purposes only. It is not investment advice or a recommendation to buy or sell any security.
Every investment decision remains entirely your own responsibility.
Isn't it better to just buy an ETF?
A broad ETF spreads money across hundreds of companies with little effort, and many investors use one.
Ploutos does not try to talk you out of it. It is for those who also want to pick individual stocks, and to do it with data rather than tips.
It is useful even if you invest mainly through ETFs: see what each fund holds, how much it overlaps with others and which companies your money ends up in with the portfolio x-ray.
What happens when the company reports new results?
Each analysis keeps the figures of the day it was made, with their dates, so you always know what it rests on.
When the company files new results with the SEC, you see it on the analysis and can run it again on the new figures. The new analysis shows what changed since the last one.
Can I keep or share an analysis?
Yes. Every analysis stays in your history, and you share it with a link.
On the subscription plans you also download it as a PDF, in the same order and with the same figures as the page.
