Explain This like i am 5

✨ Inspiration In a world flooded with complex content, we noticed a gap: there’s no easy way to understand difficult topics based on your current learning level. Whether you're 5 or 25, the need to simplify and scaffold knowledge is universal. Inspired by the classic Feynman Technique and the idea of explaining to a child, we decided to turn that into an interactive voice-based tool.

🛠️ What it does “Explain This Like I’m 5” is a simple tool where you speak or paste any text, and the app explains it at five different age levels: 🧒 Age 5 | 👦 Age 10 | 🧑 Age 15 | 🧔 Age 20 | 👨‍🏫 Age 25

Each explanation is also read aloud using ElevenLabs Text-to-Speech, with voice tones that match each age group. It’s great for learners of all ages, non-native speakers, kids, teachers, or even adults trying to refresh their understanding of something complex.

🔧 How we built it We used:

React + Tailwind CSS for a clean, responsive UI

OpenAI GPT-4 to generate age-specific explanations

ElevenLabs for both:

Speech-to-Text (voice input)

Text-to-Speech (playback of each explanation)

Web Speech API as a fallback for STT

A custom-built prompt to format explanations clearly and consistently

A responsive layout that works beautifully on mobile and desktop

The Bolt.new black badge placed fixed on the bottom-right as per guidelines

🚧 Challenges we ran into Formatting GPT responses into clean, separate explanations for each age level

Ensuring voice playback was smooth and matched the tone of each explanation
