Most people who land here already use one of these tools and want to know whether switching is worth an afternoon. So this page puts 12 of them in one table — the cheapest paid plan of each with the day we read its price, whether there is a free plan, whether you can edit a discounted cash flow yourself, how many valuation models stand behind the figure you are shown, and which markets each one covers — and then says who each tool is genuinely the best choice for.
Lemma Analysis is our product, so read this as a comparison written by one of the 12. We have tried to make it checkable rather than neutral: every competitor price comes from that company’s own pricing page and carries the date we read it, every row says what the tool says about itself, and the section after the table lists where Lemma Analysis falls short.

The search reaches any company listed on NASDAQ or NYSE — stocks, ADRs and ETFs — and nothing else, and the screener covers about three thousand US-listed companies and ADRs. If most of what you own is listed in London, Frankfurt or Tokyo, Simply Wall St, Morningstar, Yahoo Finance, Koyfin, TIKR, GuruFocus, Stock Unlock and Stock Analysis all reach further than we do.
The first release went out in March 2026, and features still change month to month — the changelog is public. Morningstar and Yahoo Finance have decades of history behind them; we have the months since then.
We publish no buy or sell ratings, no analyst price targets and no consensus revenue forecast. The four models start from the company’s own filings, and the one analyst figure the app carries is the forward earnings estimate Graham’s formula can use. If an analyst’s view is what you want, Morningstar is built around it; for consensus estimates, Koyfin and TIKR; for other investors’ written analysis, Seeking Alpha.
The screener and portfolio analytics are part of Ultimate — $8.99 a month or $79.99 a year, 7-day free trial included — and so is valuing more than 3 companies a day: the four valuation models open on the free plan, signed out too, up to that many companies. After the trial the free plan keeps 1 portfolio of up to 10 positions, 1 watchlist of 5 tickers, 5 journal entries and the Quality Score.

A visual, beginner-friendly research tool — but its valuation model is fixed.
A fast screener and market map — but no intrinsic-value tooling.
Deep analyst research — but the valuation is theirs, not yours.
Free quotes and news — but shallow analytics and no DCF.
Deep screening and analytics — in a dated, steep-learning-curve interface.
Terminal-style charts and dashboards at a retail price — but no model that turns a multiple into a value.
A friendly, editable DCF for stocks worldwide — one calculator, though, and notes without a review date.
Decades of global data, guru portfolios and a dozen valuation figures — at a much higher price.
The broadest free data on almost any ticker, and a quick DCF — but one figure, and no thesis.
Global institutional data and an editable P/E model — but no DCF, and no portfolio of your own.
Crowd-sourced analysis and quant grades — but no valuation you can drive yourself.
It depends on what you want the tool to do. For visual reports on stocks across many markets, Simply Wall St; for scanning the US market fast, Finviz; for analyst research and funds, Morningstar; for deep screening, Stock Rover; for a free first look at almost anything, Yahoo Finance or Stock Analysis; for charts and macro dashboards, Koyfin; for decades of global financials, TIKR or GuruFocus; for guru portfolios, GuruFocus; for one editable DCF worldwide, Stock Unlock; for other investors’ analysis, Seeking Alpha. If you want to value a US company yourself, several ways, and keep a written thesis for each holding, that is what Lemma Analysis is built for.
All 12 can be used without paying, with different ceilings. Yahoo Finance and Stock Analysis give away the most data; Finviz is free with delayed data; Simply Wall St gives five company reports a month; Koyfin two watchlists and two screens; Stock Unlock three DCF valuations a week; TIKR covers US stocks only on its free plan; Seeking Alpha keeps its analysis behind Premium; Stock Rover, Morningstar and GuruFocus keep a limited free account. Lemma Analysis keeps 1 portfolio of 10 positions, watchlists, the journal and the Quality Score free, and values 3 companies a day with all four models; the screener is part of Ultimate.
Lemma Analysis is built around it: open a company’s Intrinsic Value tab and the inputs to Advanced DCF, Ben Graham, Simple DCF and the Dividend Discount Model are yours to change, each with a bear, base and bull case. Three others let you edit one: Stock Analysis has a free DCF calculator, Stock Unlock a DCF on the base metric you pick, and GuruFocus a discounted-earnings calculator. TIKR’s model is P/E-based rather than discounted; Simply Wall St shows a fair value from its own fixed model, Morningstar an analyst’s, Stock Rover a computed one; Finviz, Yahoo Finance, Koyfin and Seeking Alpha show ratios or grades rather than a discounted cash flow. The four models are free for 3 companies a day with no account needed, and unlimited on Ultimate, which every new account gets for seven days without a card.
Not today. The search reaches any company listed on NASDAQ or NYSE, including the ADRs of foreign companies listed there, and nothing else. If most of what you own is listed elsewhere, every tool in the table except Finviz and Seeking Alpha covers more markets than we do.
It is free to start, with no card. Ultimate is $8.99 a month or $79.99 a year, and every new account gets seven days of it; there is no research tier above it.
Each competitor price was read from that company’s own pricing page on the date printed under it; the latest check was Oct 14, 2026. They are list prices for the cheapest paid plan, in US dollars, before tax and promotions. Vendors change them, so check their page before you buy.
No comparison written by one of the products in it can be, which is why it says so at the top: Lemma Analysis is ours. What we can do is make it checkable — dated prices from each vendor’s own page, our limits stated, and a one-to-one page for every tool with at least one row it wins.
Free to start. No credit card.
