Dasher is a zooming predictive text-entry system for accessibility and augmentative communication (AAC). It lets you write using minimal physical input — eye gaze, a mouse, a single switch, a joystick, or touch.
Looking for apps, downloads, or user docs? Visit dasher.at — that's the end-user website.
Dasher v6 is one shared engine consumed by native frontends. Each frontend owns only input, rendering, and platform UI; all the prediction logic lives in the engine.
