+# FlowGram.AI
+
+FlowGram is a node-based flow building engine that helps developers quickly create workflows in either fixed layout or
+free connection layout modes. It provides a set of interaction best practices and is particularly suitable for visual
+workflows with clear inputs and outputs.
+
+In the current AI boom, we are also focusing on how to empower workflows with AI capabilities, hence the AI suffix in
+our name.
