## Future-Ready with Local AI SparkChart is built for the next generation of web browsing. We have integrated a powerful AI assistant designed to generate diagrams from natural language prompts and automatically refactor your chart logic.
Note: These AI features are currently deactivated. They will be automatically enabled as soon as Google Chrome rolls out official support for Gemini Nano (Built-in AI) on your device. This ensures the AI runs entirely locally on your machine, keeping your data 100% private.
