Alfred

Alfred treats the launcher as a tiny command language. You don't just type a query; you type a keyword that routes it — a prefix selects a web search, a file filter, a workflow, a calculation — and the rest of the line becomes that command's argument. This explicit grammar makes Alfred predictable in a way pure fuzzy matchers aren't: the same input always reaches the same handler. Workflows extend this with a visual node graph that wires triggers to actions, so power users build bespoke pipelines without leaving the bar. The interface itself is deliberately spare, a single text field over a thin result list. The flip side of the keyword model is friction for newcomers, who must memorize prefixes before the speed pays off.
