How it works

Three steps to clarity.

Import what you own

Drop a brokerage statement. Marisco resolves and prices every position — across brokers, with zero dev setup.

Understand it

See your real exposure, concentration, and performance — explained in plain language, not jargon.

Get better at it

The reasoning is visible and learnable, so you build judgment over time. A teacher, not a black box.

Is Marisco a financial advisor?

No. Marisco is an educational analysis tool — it explains your holdings, it doesn't tell you what to buy or sell.

Where does my data go?

Marisco runs on your own agent and your data stays yours.

Curious about markets? Start with the one you already own.

Most trackers

Show performance, then leave you to guess what it means.

Robo-advisors

Make the decisions for you. You learn nothing.

Marisco

Explains your real holdings so you decide — and get better.
