Ditto centralizes a product's standards, strings, and decision history into one source of truth, then connects that system everywhere copy is drafted and shipped: Figma, GitHub pull requests, agentic tools like Claude Code and Cursor, and your production codebase. Strings and style guides are pulled in automatically wherever text is generated — by humans or AI — and the system itself learns as teams use it, surfacing recommendations based on real usage.
