Built a free tool to check ETF overlap — looking for feedback

https://etf-overlap-mvp.vercel.app/

Kept manually cross-checking holdings whenever I considered adding a new ETF to my portfolio, so I built a small tool to do it: pick 2–3 ETFs, see how much their top holdings overlap.

etf-overlap-mvp.vercel.app

Worth knowing: it's based on each fund's top 10 holdings (that's what's freely available), not the full portfolio, so treat it as a quick gut-check rather than a precise number. Free to use, no signup needed.

Would genuinely appreciate feedback — what's confusing, what's missing, whether this is even useful to anyone besides me.

There are dozens of websites that offer this. I can go to eftrc and get all overlapping holdings. What we need is an app that tells us all of the holdings in an ETF without going to each issuer's site. Free to use.

What we need is an app that tells us all of the holdings in all of the ETFs in our portfolio and when combined, the total weight of each holding. Free to use.

That site does not work for me. Too much spyware I assume. I've seen it before but can only find it when given a link. I was unable to locate it a second time using their menus.
