Teenvest – Real-World Finance for Teens, Powered by Perplexity AI

💡 Inspiration

Growing up, many of us never received proper financial education, and it's a harsh reality that 90% of students graduate without understanding money. We wanted to change that. Our inspiration for Teenvest came from imagining a world where teenagers could explore investing, trading, and saving in a risk-free, fun, and educational way—just like a finance playground. With the help of Perplexity's powerful, grounded AI, we realized we could finally make financial literacy accessible, personalized, and trustworthy.

📚 What We Learned

While building Teenvest, we dove deep into:

Canadian financial systems (TFSA, FHSA, RRSP, etc.)
How to use Perplexity API effectively for contextual and citation-rich responses
Designing UI/UX that is both intuitive and engaging for younger users
Ensuring AI responses are not just accurate but age-appropriate and simple to understand

We also learned the importance of limiting search domains to trusted Canadian finance websites like canada.ca, wealthsimple.com, and morningstar.ca for safer, more relevant content.

🛠️ How We Built It

Frontend: Built using Next.js with Tailwind CSS for a responsive and clean interface
Backend: Next.js Route handler layer that manages Perplexity requests.
AI Integration: Used Perplexity API with custom system prompts to provide contextual, page-aware financial advice grounded by real citations
Gamification: Simulated wallets, trading accounts, and reward systems to keep users engaged while learning
Security & UX: Simple PIN-based login for kids to ensure ease of access without over-complication

🧩 Challenges We Faced

Contextual Awareness: Making sure the AI always knows what page the user is on and responds accordingly. We solved this with dynamic system prompts tied to app state.
Citations & Domain Restriction: Ensuring the AI gives answers only from trusted finance websites was tricky. Perplexity’s domain-restrict feature was crucial here.
Age-Appropriate Language: We had to iteratively test and refine prompts to make sure the AI’s explanations were simple enough for a 12–17-year-old to grasp.
Balance Between Education and Fun: Gamifying without compromising accuracy took time, but feedback loops and a playful UI helped us bridge the gap.

🚀 Final Thoughts

Teenvest is more than a project—it’s a mission to transform financial education for teens. By merging gamified learning with the intelligence and trustworthiness of Perplexity, we created a risk-free, engaging environment where teens can confidently learn how money works. We believe this is the future of education—personalized, intelligent, and fun.
