The Opportunity

Problem

Enterprise teams experience low adoption of AI tools due to steep learning curves and inadequate training for non-technical users.

Solution

PromptCoach is a conversational AI coach that teaches non-technical users how to use AI tools through natural dialogues, adapting to their pace and role. It simulates real scenarios, critiques prompts, and suggests improvements on-the-fly. Enterprise admins monitor chats for compliance and progress.
