💡 Inspiration

PitchCoach AI was born from seeing how many small vendors and informal entrepreneurs struggle to communicate their value confidently. Despite offering great products or services, many lack formal sales training, access to digital tools, or time to improve their pitch. We wanted to build something that could fit in their pockets and help them practice, improve, and perform—anytime, anywhere. The vision was clear: a voice-interactive coach that doesn’t need tech skills to use but delivers real, measurable improvement.

⚙️ What it does

PitchCoach AI is a mobile-first, voice-interactive AI coach that helps small vendors sharpen their sales pitch. It provides:

  • Real-time voice recording with animated soundwaves
  • AI-powered scoring on tone, structure, and persuasiveness
  • A growing library of practice scenarios at multiple difficulty levels
  • Progress tracking via an intuitive analytics dashboard
  • Group training features for teams or cooperatives
  • A responsive, low-tech-friendly interface with smooth UX

All designed to help users confidently improve their communication and close more sales.

🏗️ How we built it

Frontend: We used a modern UI framework to design a sleek mobile interface with smooth gradients and accessible controls. Voice Interface: Integrated a speech-to-text engine with animated soundwave visual feedback. AI Engine: Trained NLP models to assess speech tone, structure, and persuasiveness based on effective sales principles. Backend: Developed secure APIs for user management, analytics, and scenario delivery. Design: Focused heavily on mobile-first principles, ensuring usability on low-end devices with minimal friction.

🧗 Challenges we ran into

Voice Analysis Accuracy: Getting consistent and fair AI scoring across different accents and speech styles required careful model tuning. Device Performance: Making sure the app ran smoothly on lower-spec smartphones forced us to optimize for performance without sacrificing UX. Scenario Design: Crafting realistic, culturally appropriate sales scenarios that are both useful and engaging was harder than expected. Balancing UX: We had to strike a balance between modern design and functional accessibility for all user types. and it is developed in bolt.new in the freemium version

🏆 Accomplishments that we're proud of
