Leish · ليش؟

Is training really the answer? Leish is an AI performance-diagnosis tool for training consultancies and L&D teams. A manager asks for a course; Leish reads the company's tickets, surveys, interviews and policies, finds the real cause of the performance gap (Gilbert's Behavior Engineering Model), and a person approves the diagnosis before any fix is designed.

This repository is the web app. The AI agents run in n8n (LS 01 to LS 07 workflows, Gemini, Qdrant). The app never calls the AI directly.
