Every assessment is backed by a DCF model, peer comparison, and an explanation of why the rating is what it is — no black-box AI scores. Free tier covers basic analysis on any stock; Premium (~$16/month annual) unlocks unlimited deep reports and portfolio tracking.

Before vs. after using this prompt
Investor researching SHOP spends two weekends reading 10-Ks, building a clunky DCF in Excel with assumptions they're not confident in, reading conflicting analyst reports, and ending up with a fair value range of '$50 to $150' that doesn't help them decide. They buy or pass based on gut.
Same investor opens Simply Wall St, sees the SHOP snowflake at a glance (good Future and Past, average Value, weak Health due to leverage), reads the AI-generated DCF showing fair value of $78 with sensitivity to revenue growth assumptions, and the moat analysis explaining merchant lock-in. 45 minutes later they have a defensible thesis and entry price.

Open Seeking Alpha PremiumFrequently asked
Can I trust an AI-generated DCF over building my own?
For a starting point, yes — the AI DCF transparently shows its assumptions (growth rate, discount rate, terminal multiple) and you can sanity-check whether you agree. Building your own DCF only adds value if you have a differentiated view on one of those assumptions. If you're going to use the consensus growth estimate anyway, the AI DCF gets you to the answer in 60 seconds instead of 60 minutes.
Is fundamental analysis even useful in a market driven by sentiment and momentum?
Useful for time horizons longer than 12 months; less useful for shorter horizons. The market can stay irrational for a year or more — sentiment dominates over weeks and months. But over 3–5 year holding periods, fundamentals reassert themselves and valuations mean-revert. If you're investing for retirement, fundamentals matter; if you're trading the next earnings cycle, they don't.
What's a 'moat' and how do I actually identify one?
A moat is a structural reason a company can sustain above-average returns on capital over time without being competed away. The four most reliable sources are network effects (more users make the product more valuable — Visa, Meta), switching costs (high pain to leave — Oracle, Salesforce), scale advantages (cost per unit drops with size — Amazon, Costco), and intangible assets (brand or IP — LVMH, pharma patents). If you can't name which of these applies, the moat probably isn't real.
