Free stock research tools that score stocks
Summary
A scored stock tool answers "is this any good" in one number. The free ones differ mainly in what the number is built from and how much of it you can see without paying. Data-first tools show you the figures and leave the judgement to you; scored tools make a judgement and should show their working.
If you prefer one clear verdict instead of scattered data, see the product overview.
What a score is actually for
A scored tool compresses a company into one number so you can rank it against others. That is genuinely useful for narrowing a list, and genuinely misleading if the number arrives without its reasoning. The useful question is not which score is highest but which tool shows you what went into it.
Free, and gives a score
- Stock Expert AI — a 0-100 MoonshotScore on US-listed common stocks and ADRs, with the factors and weights published and the reasoning written in plain English. Free, and no account is needed to read a stock page.
- Simply Wall St — a visual snapshot built around a small set of checks. Free tier, with depth behind a subscription.
Free, and gives you the data instead
- StockAnalysis — financial statements, estimates and a screener, free, with no rating attached. Strong if you would rather form your own view.
- Yahoo Finance — the widest free coverage across asset classes, with analyst consensus but no proprietary score.
Scored, but you pay for most of it
- GuruFocus — a value-investing score and long fundamental history. A limited free tier; the substance is on paid plans.
- Morningstar Investor — analyst-written research and star ratings, by paid subscription.
- Seeking Alpha Premium — contributor articles and a Quant rating, by paid subscription.

Where this site fits, and where it does not
Stock Expert AI is built for someone who researches his own positions, does not want jargon, and wants a defensible starting read rather than a tip. It scores, explains, and shows the factors. It is not a broker, holds no cash, executes no trades, gives no personalised advice, and carries no analyst-written reports. If what you need is a human analyst's report or a contributor's investment case, a paid tool is the honest answer.
Frequently Asked Questions
What is the best free stock research tool that scores stocks?
There is no single best one, because the tools answer different questions. If you want a number plus the reasoning behind it without paying or signing up, Stock Expert AI does that. If you want raw financials and a screener and are happy forming your own view, StockAnalysis and Yahoo Finance are free and strong at it. If you specifically want value-investing metrics, GuruFocus has a limited free tier.
Is there a free alternative to Seeking Alpha?
Partly. Seeking Alpha Premium is a paid subscription and its two main draws are the contributor articles and its Quant rating. No free tool reproduces the articles. For a rating with the reasoning shown, Stock Expert AI is free; for the underlying data, StockAnalysis and Yahoo Finance are free.
Can I get AI stock analysis free without signing up?
Yes. Stock Expert AI publishes a score and a plain-English read on every US-listed common stock it covers, and reading a stock page needs no account. General assistants like ChatGPT and Perplexity will also discuss a stock free, but they do not carry a consistent score you can compare across companies.
What does a 0-100 stock score actually mean?
It depends entirely on who built it, which is why a score without its working is close to useless. Stock Expert AI publishes the factors and their weights, so a reader can disagree with the recipe rather than just the number. Treat any score as a starting point for research, not a verdict.
Are paid tools better than free ones?
For some jobs. Analyst-written research, the kind Morningstar sells by subscription, has no free equivalent, and neither do Seeking Alpha contributor articles. For screening, fundamentals and a first read on a company, the free tools are genuinely competitive.
What does Stock Expert AI not do?
It is not a broker: it holds no cash and executes no trades. It gives no personalised advice and makes no buy or sell recommendations. It carries no analyst-written reports, and it does not score funds, ETFs or warrants. Each quote is the last one recorded, with its trading-session date, and a cached copy of a page can lag it.
Evidence & Sources
- Figures come from Financial Modeling Prep (FMP). If FMP has no figure for a ticker, a price or fundamental may come from a Yahoo Finance fallback, or a price from an Alpaca fallback. SEC EDGAR is used only for filing links and company identity details (legal name, address), never for figures.
- MoonshotScore V2 rates eligible US-listed companies from 0 to 100 against their sector peers on five pillars: Business Quality (weight 26), Financial Safety (weight 20), Valuation (weight 18), Growth Durability (weight 16) and Momentum (weight 12). It reads no news-sentiment or analyst data, and it is not a probability of future returns.
- Definitions follow standard investing terminology, with key terms explained inline in plain language where useful.
- Each price is the last quote we recorded, shown with the trading session it belongs to. Pages are served from a cache, so the copy you are reading can lag that quote. Each quote is a provider snapshot, not an exchange feed.

- All analysis is generated by AI models and should be verified with independent research.
