Flowchart Creator for Visually Impaired Users

Koi Charts is an accessible, voice-powered flowchart creator designed primarily for visually impaired users. It allows users to build and edit flowcharts through naturally spoken commands, reducing dependence on mouse-based visual tools. Users can add, rename, connect, arrange, and delete nodes using conversational instructions and receive concise spoken feedback about each action. A tactile display simulator converts the flowchart into raised-pin patterns, while Braille context communicates node labels, connections, and directional information. The visual canvas, tactile representation, spoken feedback, and accessible text outline all share the same underlying chart structure, keeping every view synchronized. Koi Charts also provides keyboard controls, structural chart checking, guided route testing, automatic arrangement, editable project files, and multiple export formats. These features help visually impaired users independently create, understand, verify, and share flowcharts while collaborating with sighted users through the same workspace.
