I've been through two iterations with this tool, and overall I found it genuinely valuable.
What I like most is how clearly the feedback is structured. It doesn't just comment on slide design - it reviews the deck's structure, messaging, and presentation separately, making it easy to prioritize improvements. It also looks for logical inconsistencies and contradictions, essentially simulating how a real VC evaluates a startup. In my experience, that's exactly what investors do: they look for weak assumptions and places where the story doesn't hold together. This makes it a great way to pressure-test your pitch before sending it to investors.
Overall, it's a very impressive product, and I sincerely hope more startup founders use it before fundraising.
