Mixboard (https://labs.google.com/mixboard/) generates visual design boards from an instruction, on a whiteboard fed as it interacts with AI.

Once the instruction has been given, the visuals are generated with sometimes questions to specify the request.
Each generation can be questioned, individually or in groups, and edited. Variations can be requested.

It is possible to import your own photos from Google drive or Google photos, or to add text.

Based on Nano Banana, Mixboard remains dedicated to ideation and builds can be less detailed than when using in another tool.

Free in public beta, seems unlimited.
