🌟 AI Guru — Project Submission Write-up

💡 Inspiration

Education is drowning in static notes, endless slides, and boring videos that don’t teach — they just talk. Students want a real teacher: someone who explains, demonstrates, answers doubts, and guides them personally. So we asked: What if every student had an AI-powered teacher who looked real, spoke naturally, and generated fresh video lessons instantly? That idea became AI Guru — an AI educator that teaches, speaks, gestures, answers doubts, and creates personalized video lectures on any topic.

🚀 What it does

AI Guru is a full AI-driven learning system that:

  • 🔹 Generates personalized video lectures using AI avatars
  • 🔹 Creates complete scripts, thumbnails, captions, and summaries
  • 🔹 Offers real-time doubt solving like a live teacher
  • 🔹 Allows students to choose their AI teacher avatar & voice
  • 🔹 Stores every lecture online for future playback
  • 🔹 Gives a smooth, interactive video player with captions & speed control
  • 🔹 Makes learning faster, visual, and more engaging

In short: You type a topic → AI Guru generates a high-quality video lecture in minutes.

🏗️ How we built it

AI Guru is powered by a multi-layer architecture:

Frontend (Base44)

  • Custom React-based UI inside Base44
  • Topic input + avatar/voice selection
  • Progress tracker (“Generating Script → Video Rendering → Finalizing…”)
  • Video player with captions, speed, fullscreen, seek, etc.

Backend Functions

  • Script generation using LLM
  • HeyGen API for real MP4 generation
  • Polling engine for video rendering status
  • MP4 download + upload to cloud storage
  • Auto-captions generator (.vtt)
  • Auto thumbnail generator
  • Lecture metadata storage in Firestore

Tech Stack

  • Base44 (frontend + backend)
  • HeyGen API (AI avatars + video rendering)
  • LLM text generation
  • Firebase-style storage
  • Axios for async requests
  • VTT caption generator

Everything is fully automated — no manual editing, no slides, no templates.

🧩 Challenges we ran into

  • Getting the video generation API and Base44 backend to communicate reliably
  • Handling long script processing delays during video rendering
  • MP4 downloads failing due to CORS and binary buffer issues
  • Ensuring smooth playback on all devices (Safari required special handling)
  • Keeping API keys secure inside Base44 (Secrets only work with backend enabled)
  • Auto-generating captions & thumbnails without external tools
  • Avoiding slide-based fallback when the video engine fails

Each challenge forced us to refine the pipeline until it became stable and fully automated.

🏆 Accomplishments that we're proud of

  • Built a fully automatic video lesson generator from scratch
  • Integrated HeyGen API flawlessly for AI teacher videos
  • Achieved zero slides — only real MP4 output
  • Created end-to-end system: script → video → captions → thumbnail → player
  • Designed a clean UI that feels like an educational version of Instagram
  • Implemented real-time doubt solving through AI

Most importantly: We turned raw text into full teaching videos without human editing.

📚 What we learned

  • How to integrate video rendering APIs with serverless backend functions
  • How to handle asynchronous long-running tasks (video polling)
  • How to generate captions programmatically from LLM output
  • How to build scalable AI features inside a no-backend platform like Base44
  • How to structure clean UX for AI-generated content
  • Importance of securing API keys and stable endpoints

We learned that AI video generation is powerful — but requires careful engineering to feel seamless for students.

🔮 What’s next for AI Guru

The next upgrade roadmap:

  • 🎤 Voice cloning for personalized teachers
  • 🧑‍🏫 Create your own avatar using a selfie
  • 🧪 Interactive quizzes automatically generated from the lecture
  • 🎯 Adaptive learning paths based on student performance
  • 📱 Launch mobile app version (Android/iOS)
  • 🧠 Fine-tuned subject expert AI models
  • 🗂️ Community-shared lecture library
  • 🎤 Live AI teacher mode (real-time speaking avatar)

AI Guru is just beginning — the goal is to create the world’s smartest AI tutor.
