Monsa vs Simply Wall St: Two Scores, Two Different Questions
Simply Wall St scores a stock against the market - value, future, past, health, dividend, one snapshot view built for any ticker. Monsa scores a stock against the strategy you personally wrote down, re-checked every night. One asks "is this a good stock." The other asks "does this still fit what I said I wanted."
What Simply Wall St does
Simply Wall St is a stock research and screening platform. Look up almost any listed company and it renders a visual breakdown, its "Snowflake," across five areas it names on its own site: Value, Future, Past, Health and Dividend, alongside narrative analysis points drawn from the company's fundamentals. It is built to answer "is this a good stock" for any ticker a visitor types in, whether or not they own it, and it markets itself as a screener and research tool for finding and comparing companies to buy.
What Monsa does
Monsa holds the rules you wrote for how you invest and checks every stock in your book against them, every night. You describe your strategy in a sentence, Monsa proposes criteria and thresholds from it, and you accept or edit each one before it goes live. From then on, each tracked ticker gets a fit score from 0 to 100, a verdict of fits, borderline or violates, and a breakdown of exactly which criterion moved the number. Nightly re-scoring means a holding that quietly stopped matching your thesis shows up before you go looking for it.
Where they overlap
Both tools turn a pile of fundamentals into a single visual score for a stock. Simply Wall St's Snowflake and Monsa's fit score are both built on company and market data, both render as a number you can read at a glance, and both exist so you don't have to re-derive the underlying metrics by hand every time you look at a ticker.
Where they don't
This is the part that actually matters when picking between them, or deciding you need both.
Simply Wall St's score is the same for every user looking at that ticker. Two people checking the same stock's Snowflake see the same shape, because it is scored against the market and the company's own fundamentals, not against anything either of them personally believes about investing. Monsa's fit score is different by design: it depends on the strategy you wrote, so the same stock can fit one operator's book and violate another's, and it changes the moment you edit your own rules. Monsa's score is never a black box either way - every criterion that moved it stays visible in the breakdown, the same standard Simply Wall St's own transparent Snowflake sets for itself, just measured against a different thing.
Put plainly: Simply Wall St tells you how a stock looks against the market. Monsa tells you whether it still looks like what you said you'd hold.
Who should use which, or both
If you're looking for new ideas or sizing up a stock you don't own yet, a Simply Wall St-style snapshot is a reasonable discovery step - it's built for exactly that, scoring any ticker against the market with no strategy of your own required. Monsa isn't a screener and doesn't try to be one; it has nothing to say about a stock you don't hold or track.
Once you've bought something, the question changes. What matters then isn't how the stock looks against the market in general, it's whether it still clears the bar you personally set when you bought it. That's the nightly discipline check Monsa runs and a market-wide snapshot tool doesn't attempt, because it has no record of your rules to check against.
Plenty of operators would reasonably use both: a snapshot tool for finding and vetting new ideas, Monsa for making sure the ones already in the book haven't quietly drifted from why they went in.
Pricing
Monsa is $19/month, or $100/year for the first 100 annual subscriptions as a founding operator. One plan, no free tier: 5 parallel portfolios, 50 tracked tickers, 100 AI analyses a month, and 5 price targets per ticker. Nightly auto-refresh plus on-demand re-sync keeps every score current.
Simply Wall St publishes its own pricing on its site, with a free plan and paid tiers above it; check simplywall.st for current numbers, since we're not going to guess at a competitor's price list here.
Try Monsa
Monsa is at monsa.ai. The founding annual price is still open to the first 100 annual subscriptions; after that seat is gone, it's gone for the operators who didn't take it, though everyone keeps the operator number they're issued the day they join.
