Allkin is a free, open-source hand-based symbol language, available as artwork via The Noun Project and as a font via Google Fonts and Monotype Fonts. Allkin means all human connection. To contribute, see github.com/googlefonts/allkin . The system contains 195 hand gestures — aligned to the 193 UN member states plus two observer states. Symbols are organised into categories: fundamental needs, social signs, emotional indicators, and conflict and peace advisories. Combined, they enable expressive, purpose-driven communication that informs and encourages peaceful resolution. Creating a universal system is no small task — and yes, a risky one. A gesture in one culture may mean something else entirely in another. Allkin embraces these differences, offering multiple gestures for shared meanings. We ask you to use the tool respectfully — and to contribute. As an open-source project, Allkin invites collaboration and dialogue. Access the GitHub repository (link) and expand the design space.
