The pace is too fast and you spend barely any time showing off your visual workflow feature, which according to your description is your differentiator.
I would strongly recommend using some of your YC money to have a professional recreate that demo and show off what makes you unique. Even if it goes longer than two minutes - if I’m interested I’ll keep watching.
I’ll still try it out because I’m a sucker for trying out new vibecoding tools, but you’re not doing yourself any favors with that video…
