Inspiration

People often lose invoices, warranty cards, and purchase documents when they need them most. Claiming warranty service becomes frustrating because users cannot quickly find proof of purchase, warranty expiry dates, or product details. We wanted to build a simple AI-powered ownership assistant that helps users store, organize, and act on warranty information before it's too late.

What it does

WarrantyVaultAI allows users to upload invoices, bills, and warranty documents. AI extracts important ownership information such as product name, brand, purchase date, warranty period, serial number, and invoice details. Users can view all owned products in a centralized dashboard, track warranty expiry dates, generate AI-powered warranty claim emails, receive warranty reminders, and access original documents anytime.

How we built it

We built WarrantyVaultAI using React, TypeScript, and Tailwind CSS for the frontend. Supabase provides authentication, database storage, and file storage capabilities. Netlify Functions power our serverless backend. Gemini AI is used to extract structured product information from uploaded warranty documents and generate ownership insights and warranty claim emails. Reminder preferences are stored in Supabase and integrated with an email notification system using Resend.

Challenges we ran into

One of the biggest challenges was extracting consistent information from invoices that vary significantly in format and structure. We also faced issues with AI API rate limits, handling different date formats when calculating warranty expiry dates, securing API keys during deployment, implementing authentication flows with magic links, and configuring email delivery infrastructure for reminder notifications.

Accomplishments that we're proud of

We successfully built an end-to-end ownership management platform that transforms unstructured warranty documents into organized digital records. Users can upload invoices, automatically extract product details, track warranty status, generate warranty claim emails, configure reminders, and securely manage ownership records through a modern web application. We are especially proud of delivering a complete working MVP with authentication, AI integration, cloud storage, and reminder workflows.

What we learned

Through this project, we learned how to integrate AI into practical consumer workflows rather than using AI as a standalone feature. We gained experience with serverless architectures, document processing, authentication systems, cloud storage, deployment pipelines, and AI prompt engineering. We also learned the importance of minimizing unnecessary AI calls to reduce costs while maintaining a good user experience.

What's next for WarrantyVaultAI

Our next goal is to make WarrantyVaultAI a complete ownership companion. We plan to add automated warranty reminder emails, multi-document support, receipt scanning from mobile devices, repair and service history tracking, product resale value estimation, ownership analytics, and support for extended warranties. We also plan to launch a mobile app that allows users to manage all their purchases, warranties, and ownership records from anywhere.
