A free portfolio check that turns ad clicks into contacts
An investor enters their holdings and sees within seconds where the portfolio is weak. Leaving contact details gets them the full report. The free check costs Finademica nothing in AI fees.

Challenge
A retail investor sees green and red numbers in their brokerage app. They don't see that two of their funds move almost identically, how much they would lose in a market drop, or how many positions the whole portfolio really depends on.
Finademica, an investing academy, wanted a tool that shows this and brings in leads from paid ads. An older analyzer in the same group had been measured at $0.83 to $1 per asset. At a thousand visitors a day, that would be $800 spent on a day when nobody bought anything.
Solution
We built a standalone service that Finademica's other apps can use too. Most of the work is plain math: concentration, correlation, market sensitivity, risk per position. The program works all of that out at no cost. The AI only receives the finished numbers, and its job is to explain them in plain Czech.
So the free check never calls the AI. Locked results are never sent to the visitor's browser, so there is no way around the lock. The AI report runs only for someone who has left contact details. The same portfolio is never worked out twice: the report is saved and shown for free on the next visit.
The output always has the same shape. The public page and the academy each show it in their own design, and the AI text never arrives cut off.
How it works
- 1
Enter positions
The visitor types "Apple" or "gold", picks from the suggestions, then adds quantity and purchase price. No sign-up.
- 2
Free check
The service pulls market data, computes the portfolio's vital signs and runs triage. The visitor gets a score, a count of problems and one of them shown in full.
- 3
Report for contact details
After leaving contact details, the visitor gets a personal page with the full breakdown. The AI diagnosis streams onto it as the model writes.
- 4
Re-checks and history
From that page they can check the portfolio again. Each result is added to a history, so the score can be followed over time.
What it does
- Stocks, ETFs, crypto, commodities and currencies in one portfolio
- Correlation between positions: spots two holdings that are really one
- Drawdown risk, concentration, sector split, market sensitivity
- Triage for every position: critical, watch, stable
- Locked results can't be opened from the browser
- Opening the same report again costs nothing
- Daily cost ceiling: once reached, only the math runs, without AI
- One service in two places: a public page for ad visitors and the academy for logged-in students
- The contact goes straight to the CRM and is later linked to an academy account
Outcome
The tool is live at stk.finademica.com and collects contacts from Finademica's paid ads. In just under three weeks (15 Aug – 2 Sep 2026) it produced 29 reports, and the AI for all of them cost $0.44 in total.
The free check costs nothing in AI fees, so the ads don't lose money on visitors who never leave their details. The version for logged-in academy students is connected and tested, but so far most visitors come from ads.
