02Step-by-Step Guide
1

Capture Purchase Details

After buying a significant item (e.g., a TV, appliance, or bike), use your phone to take a photo of both the product and its purchase receipt.

2

Use AI to Extract Information

Process the captured images with an AI vision model. The AI should perform Optical Character Recognition (OCR) on the receipt to extract the product name, serial number, purchase date, and price.

3

Automatically Fetch the User Manual

Using the extracted product name and model number, create a function that automatically searches the web and downloads the corresponding user manual PDF.

4

Store All Assets Together

Save all the related information—the extracted data, receipt image, product photo, and downloaded manual—into a single, easily searchable record in a database.

5

Access Information On-Demand

When a product needs repair or you have a warranty question, you can quickly find the purchase date, warranty information, and user manual without searching through old emails or file cabinets.

6

Set Smart Reminders

As a bonus feature, add the ability to set future reminders, such as when a warranty is about to expire or when it might be a good time to sell a kid's outgrown item.
