Helping seniors navigate the digital world with confidence using friendly AI guidance, simple lessons, and a powerful scam detector.

Inspiration

Every time I watched an elderly person struggle with their smartphone — unable to video call their grandchildren, confused by a suspicious message, or afraid to click the wrong button — I felt there had to be a better way.

Millions of senior citizens are left behind in an increasingly digital world. Most apps are designed for young, tech-savvy users. TechBuddy was built to change that — to give every senior citizen a patient, friendly, and always available digital companion.

What it does

TechBuddy is a free AI-powered web app that helps senior citizens:

  • Ask Buddy — Get instant answers to any tech question in simple, clear, step-by-step language
  • Structured Lessons — Learn everyday tech skills at their own pace
  • Scam Shield — Paste any suspicious message and AI instantly identifies if it is a scam
  • Quick Actions — One tap access to the most common tasks
  • Voice Input — Speak questions out loud for seniors who struggle to type

How we built it

TechBuddy was built using:

  • Flutter Web — Cross platform framework for building the UI
  • Groq API — Free AI API powering the Buddy chat assistant
  • Shared Preferences — Local storage for saving user progress
  • Web Speech API — Browser built-in voice input support
  • Netlify — Free hosting and deployment
  • GitHub — Version control and submission The app follows an accessibility-first design philosophy with large text, high contrast colors, warm cream backgrounds, and minimal navigation to ensure seniors can use it without any assistance.

Challenges we ran into

  • Accessibility vs Aesthetics — Balancing a visually appealing design with the large text and high contrast requirements for elderly users was a constant challenge throughout development

  • Flutter Web Performance — Flutter Web can be slow to load. We optimized by removing heavy packages, using system fonts, and building in release mode

  • AI Tone for Seniors — Getting the AI to consistently respond in simple, patient, and encouraging language required careful prompt engineering in the system instruction

  • Deployment Issues — Configuring Netlify to correctly build a Flutter Web app required solving multiple asset path and environment variable errors

  • Voice Input on Web — The Web Speech API behaves differently across browsers, requiring fallback handling for unsupported environments

Accomplishments that we're proud of

  • Built a fully functional AI-powered web app from scratch that is actually usable by real senior citizens today — not just a prototype

  • Accessibility-first design — Every screen, button, and interaction was designed with elderly users in mind. Large text, high contrast colors, voice input, and simple navigation make TechBuddy genuinely inclusive

  • Scam Shield feature — Building an AI-powered scam detector that explains results in simple language felt like a real breakthrough. This feature alone could protect thousands of seniors from financial fraud

  • Personalization without login — We created a warm, personal experience where the app remembers your name and greets you every time — without requiring seniors to create an account or remember a password

  • Successfully deployed a Flutter Web app on Netlify with a live public link — making TechBuddy instantly accessible to anyone in the world with a browser

  • Voice input integration — Allowing seniors to speak their questions out loud removes one of the biggest barriers elderly users face with technology

  • Clean professional UI that looks and feels like a real product, not a hackathon project

What we learned

  • Designing for accessibility teaches you to design better for everyone
  • Flutter Web is a powerful but underutilized tool for rapid web development
  • AI tone and personality matter as much as the answer itself
  • Senior-friendly UX requires rethinking every assumption about how users interact with technology

What's next for TechBuddy

  • Urdu language support — Pakistan has millions of elderly citizens who are more comfortable in Urdu than English. Adding full Urdu language support would dramatically increase TechBuddy's reach and impact across South Asia

  • Family dashboard — A companion portal where family members can monitor their elderly parent's progress, see which lessons they completed, and send encouraging messages directly through the app

  • Offline mode — Many seniors in developing regions have limited internet access. An offline mode with pre-loaded lessons and basic guidance would make TechBuddy accessible everywhere

  • Mobile app — Publishing TechBuddy as a native Android and iOS app to reach seniors who primarily use smartphones rather than laptops or desktops

  • NGO and hospital partnerships — Partnering with elderly care homes, hospitals, and NGOs to introduce TechBuddy to seniors who need it most

  • Progress tracking and certificates — Awarding seniors a digital certificate when they complete all lessons — giving them a sense of accomplishment and pride in their learning journey

  • Video lessons — Adding short, simple video tutorials alongside the text-based lessons for seniors who learn better by watching

  • Emergency SOS button — A one-tap button that instantly contacts a family member if the senior feels confused, lost, or in danger
