Questions
Frequently asked questions
Is Knowstox free?
Yes — Knowstox is completely free. You can research five stocks without even signing in; after that, sign in with Google to keep going. No credit card, ever.
Where does the data come from?
Company financials come straight from official SEC EDGAR filings, combined with live market data. AI then translates the numbers into plain-English explanations.
Is this investment advice?
No. Knowstox is an educational research tool. It helps you understand a stock — it never tells you to buy or sell. Always do your own research.
How is the fair-value range calculated?
We use a discounted-cash-flow (DCF) model and show the result as a range rather than a single number, because real valuation involves uncertainty. It’s an estimate to inform your thinking, not a price target.
Do I need a finance background to use it?
None at all. Knowstox is built for everyday investors and beginners — every metric comes with a plain-language explanation.
Why do I have to sign in?
Signing in with Google lets you research beyond the free limit and save what you look at. We don’t spam you and we don’t sell your data.
