Built an AI tool that grades a designer's portfolio and tells them what to fix.

About

FixMyPortfolio is a free tool from Flux Academy. A designer pastes a link to their portfolio and gets back a score, a breakdown across six categories, a card worth sharing, and a report on what to fix.

Native built what sits under it: the product, the service that produces a grade, and everything that makes a public tool like this safe to put your name on.

The challenge

Most marketing sites cost the same whether ten people visit or ten thousand. This one spends real money every time somebody uses it, and anybody can use it, free. A designer grading their own portfolio and a script grading ten thousand look identical at the door.

It also has to open whatever link a stranger hands it, from Flux's own servers.

So the risk was never whether it would work. It was whether a good week, or one person with bad intentions, could arrive as an invoice nobody agreed to.

The solution

Anything that is not a real person is turned away before it costs a penny, and turned away invisibly. No puzzle, no checkbox: someone landing on a phone decides in two seconds whether this is worth their time, and a captcha there loses more real designers than it stops fake ones.

Under that sit limits on how much any one person can use it, and a ceiling on the day. Above all of it sits a hard cap on spending that nothing in the code can talk its way past, set by Flux, at whatever number they are comfortable with. Everything else exists so the tool never gets near it.

And it cannot be tricked into opening something it should not. A hostile site can answer a request by pointing somewhere else, and somewhere else can be inside the network it is being asked from. Every step is checked, not just the first.

A grade that is wrong is worse than no grade, because a designer will act on it. Getting that right took longer than everything above.

The card is the part that gets posted, so nobody can forge one carrying a score that was never calculated, and one that travels a long way costs no more than one that does not.

The results

FixMyPortfolio is live at fixmyportfolio.ai, and Flux can point anyone at it without watching the meter.

The most a day can cost is a number they chose, not one they find out about. The credentials that spend money never reach a visitor's browser, so there is nothing in anyone's hands worth stealing. And a designer gets a real answer rather than a number: six categories, the evidence behind each score, and the one thing to fix next.
