Why I built it:

every time I started a new app idea, I ended up juggling four tools. A whiteboard to brainstorm, a diagram tool for the flows, a design tool for the screens, and a prototyping tool to click through it all. Nothing was connected, and the AI tools I tried gave me pictures I couldn't actually edit.

So I built one canvas for all of it.

In Builderii you can:

Describe an app and get linked, clickable screens in device frames, made of real editable components, not an image
Draw flowcharts, mind maps, sequence diagrams, sitemaps, roadmaps and database diagrams right next to your screens
Press Play to click through the prototype, then share a test link (testers don't need an account) and see where people tap and drop off
Work together live with cursors, comments and @mentions, plus a whiteboard you can sketch on, even from your phone
Connect Claude or ChatGPT and have them draw on your boards for you
The AI decides what goes on the board, and Builderii's own layout engines decide where it goes. Everything comes out tidy and stays editable.

What feedback would help most:

1. Was the first board the AI made for you a useful starting point, or did you end up redoing it?

2. Where did editing feel slow or confusing?

3. What would you need before moving your team's wireframes or diagrams over from the tool you use now?

I'm here all day and reading every comment. Thanks for checking it out! 🙏
