   we built sleek.design: you describe your app idea and it generates mobile mockups designs. it is possible to export them into html, react or figma. it is also possible to get a prompt that can be pasted into bolt and will generate the actual app starting from the design created. this is our third huge pivot and honestly the last shot we're giving ourselves. quick backstory: we're 3 bootstrapped builders. launched about a year ago with what's now on v1.reweb.so, basically a visual builder for nextjs/tailwind/shadcn. it went pretty viral and started growing, but we couldn't get past…

    Instantly turn any API into a native app, with a single JSON markup▲14

    Hi guys, I've worked on several apps in the past couple of years, and found that it takes too much effort going from having an idea to building an app and having the world use it.
