TechBuddy

AI companion helping senior citizens master technology with confidence

Comment

Inspiration

My grandfather once called me frustrated because he could not figure out how to video call my aunt. That moment stuck with me. He is not alone — millions of seniors feel lost, embarrassed, and left behind in a world that has gone digital without them.

Most apps are built for young people. TechBuddy was built for everyone else — the grandparents, the retirees, the people who just want to stay connected without feeling confused.

What it does

TechBuddy is a free AI-powered web app built specifically for senior citizens. No downloads, no accounts, no passwords. Just open the link and start learning.

  • Ask Buddy — Ask any tech question and get a simple, step-by-step answer
  • Structured Lessons — Learn real skills like video calling and sending photos at your own pace
  • Scam Shield — Paste any suspicious message and AI instantly tells you if it is a scam
  • Voice Input — Just speak your question out loud
  • Personalization — The app remembers your name and greets you every time ## How we built it
  • Flutter Web — For building a fast, beautiful cross platform UI
  • Groq API — Powers the AI chat assistant
  • Web Speech API — Enables voice input directly in the browser
  • Shared Preferences — Saves user name and progress locally
  • Netlify — Free hosting with continuous deployment
  • GitHub — Version control and project documentation

Every design decision was made with seniors in mind — large text, high contrast colors, minimal navigation, and a friendly AI that never uses confusing jargon.

Challenges we ran into

  • Getting the AI to always respond in simple, patient language required careful prompt engineering — tone matters as much as accuracy
  • Flutter Web performance needed significant optimization to feel fast and responsive for users on older devices
  • Deploying on Netlify with Flutter required solving multiple asset and environment variable configuration issues
  • The Web Speech API behaves inconsistently across different browsers, requiring careful fallback handling ## Accomplishments that we're proud of
  • Built a fully working app that a real senior citizen could use today
  • Designed every screen with genuine accessibility in mind — not as an afterthought
  • The Scam Shield feature feels like something that could genuinely protect people from losing their savings
  • Created a personal experience with no login — seniors are greeted by name from the very first visit ## What we learned
  • Designing for accessibility makes you a better designer overall
  • The AI's personality and tone matter just as much as the answer it gives
  • Real impact comes from deeply understanding your user before writing a single line of code ## What's next for TechBuddy
  • Family dashboard — so children can track their parent's progress and send encouragement
  • Offline mode — for seniors with limited internet access
  • Mobile app — native Android and iOS versions
  • NGO partnerships — bringing TechBuddy into elderly care homes and community centers
