While this app seems sensible, I checked out the github developer account DimensionDev and it looks like their primary product is something called Mask which is something about "Web 3" crypto/NFT integration ... looks like they're a libertarian crypto grifter cult to me. They also have a gaudy, nonfunctional company page whose copyright notice reveals that is owned by a Chinese parent company with it's own stale, uninformative web page.
It's open source, and yeah, maybe they thought they'd make something actually useful ... but the source is full of red flags.
Hmm, I didn't say anything about AI (although you're right that, like most people in the fedi, I don't like it) and I'm not anti-Chinese. It's the crypto connection which raises trust issues. They list Binance as a partner and supporter, whose founder was convicted of fraud and pardoned by Trump because his sons are in on the crypto grift.
I don't think I'll be trying this app out, even though it sounds interesting, unless some trustworthy party audits the code. But hey, you do you.
