The clipboard is an unusually powerful source of context because it already contains what a person just selected. It is also unusually sensitive: fragments of credentials, private messages, client material, and unfinished work all pass through the same temporary space.
STASHE makes context explicit. A person can choose the items relevant to a task, inspect the bundle before using it, and clear it when the task ends. The product does not treat the entire clipboard history as a convenient dataset waiting to be uploaded.
Useful AI context should be narrow by default. Selection improves both privacy and the quality of the request: less irrelevant material, fewer accidental disclosures, and a clearer explanation of what the model was allowed to see.
