How StreamPack works
Magic brush: generate with AI right where you want
Mark a zone and AI puts there whatever you ask for.
The magic brush lets you edit your overlay by zones with AI. You enclose or mark the part of the design you want, type what should appear there —a character, an object, a themed decoration— and AI generates it exactly in that section, cut out and integrated with your overlay's style. It's like having a designer who adds just what you ask, where you ask, in seconds.
How it would look
How it works
Mark the zone
With the brush you enclose the overlay area where you want to add something.
Type what to put
Describe the element (for example a character or an object) and AI generates it for that zone.
It places itself
The element appears cut out (no background) and complete inside the marked area, matching your style.
Precise zone editing
Instead of regenerating the whole overlay, you change only the part you want. Great for adding details without losing what you already like.
Characters and objects on demand
Ask for the character or element you need and it appears inside the zone, cut out and ready, with no background in the way.
Integrated with your style
AI uses your design as reference so the new element matches the colors, lighting and look of the rest of the overlay.
