AI UI Sandbox
Bite-sized experiments in agent UX
Streaming text
Generated text restyling as it arrives.
Memory staleness
A memory showing its age.
Context window meter
An ambient sidebar readout of how full the current conversation's context window is — so the diminishing-returns zone is visible before you hit it. Could roll in token cost too, or stay purely about context budget.
Agent thinking
How an agent looks while it works — planning, retrieving, deliberating, hesitating.
Verification surfaces
Quick ways to confirm what an agent did without redoing the work yourself.
Provenance pills
Where a claim came from, attached to the phrase.
Reversibility
Hold-to-confirm gestures keyed to how reversible the action is.
Predictive ghosting
Drag-and-drop reordering usually feels mushy. A ghosted landing slot makes the drop read as deliberate — useful any time precise reordering matters, such as in a human-in-the-loop moment.
