Congrats to the launch, @aleksandr_heinlaid !
Not sure if I am doing something wrong, but after installed the extension, nothing showed up. Any guidance?

Aleksandr Heinlaid

@fullstack_x Thank you! Just activate it on any website other than the Chrome Web Store.

Lembit Hunt

@aleksandr_heinlaid  @fullstack_x  thanks! let us know if you won't manage the problem

Alex Lou

@aleksandr_heinlaid  @lembit_hunt Thanks both! It worked after following the guidance. Nice job!

Eljo Prifti

Easy to use and lightweight, congratulations. Is there an option to add another person to an existing sketch/project?

Aleksandr Heinlaid

@eljo_prifti Thanks, really appreciate it!

At the moment, there's no option for real-time collaboration - it's a solo tool for now.

But that’s a great idea, and I ll definitely add it to the backlog for future updates!

Jun Shen

Perfect for quick prototyping during client demos! 👀

Aleksandr Heinlaid

@shenjun Exactly! That’s one of the main use cases we had in mind - live edits during client calls . Thanks!

Lembit Hunt

@shenjun Yep quick edits during live demos was one of our core goals thanks

This makes so much sense, I’ve been in that exact spot on calls and it always feels clunky trying to mock something up on the fly. Curious, how fast is the flow from capture to editing? Feels like speed is everything here

Lembit Hunt

@alagerrka Thanks, totally get that - we've felt the same pain during calls. The flow is built to be instant: just click the icon, and you're dragging elements within seconds. No setup, no menus. Speed was a top priority from the start.

Aleksandr Heinlaid

@alagerrka thanks a lot, Oxana

Tetiana
