How are you able to determine whether this is promising? There's no details at all, just vague marketing copy. There's no actual screenshots or videos of how the workflows an interactions work, just mockups. There's no indication of why this would better than the alternative except that it's "AI".

I'm sure the web page is enough to populate their waitlist and thus met its foals, but as a HN submission this feels awful. There's just nothing of substanance to talk about.
