// monsa vs koyfin
Koyfin and Monsa answer different questions.
Koyfin is where you research. Monsa is where the conclusion you reached gets checked against reality later.
What Koyfin is for
Dashboards, financial history, estimates, comparison charts and watchlists - the analyst's workbench, without the terminal price.
Monsa holds the rules you wrote down and checks your holdings against them every night.
A Koyfin dashboard is something you look at when you go looking. Monsa is the thing that speaks up when you are not looking. The research and the maintenance are different halves of the same habit, and almost everybody does the first and skips the second.
Side by side
| What you want to do | Koyfin | Monsa |
|---|---|---|
| Compare a company to its peers | Strong. Charts, tables, history. | Not offered. Monsa compares a company to your rules, not to its peers. |
| Build a watchlist with your own columns | Yes, and it is one of the reasons people pay for it. | Watchlist exists, and every ticker on it is scored against your rules. |
| Record why you bought something | Notes, at best. | Not a note - a rule-set that gets evaluated. |
When you do not need Monsa
If you already re-open your own dashboards on a schedule you keep, Koyfin plus a calendar reminder is most of what Monsa does.
Monsa is also not a broker, does not place trades, and never says what to buy or sell. The other comparisons say the same thing about different tools, and a spreadsheet gets further than most people expect.
Rules written down while you still remember why you bought something survive the moment the price argues with you.
