Empathy Idea: AI service that writes household accounts
I have been using a household account book app on my smartphone for almost two years . Recently , due to the economic recession , I feel the need to manage my expenses more , and I thought that if AI technology were incorporated into the household account book app, I would be able to manage the household account book much more conveniently . I started to create an empathetic idea based on the idea that if AI automatically categorizes my spending history , analyzes my spending patterns , and suggests a customized budget , I would be able to reduce my daily expenses more efficiently and enjoy various benefits .
Idea draft :
The household account book AI service is used by users installing a dedicated AI household account book app on their smartphones . After launching the app , the user takes a picture of a receipt with the camera, and the household account book entry is automatically completed . At this time , the AI OCR ( optical character recognition ) function extracts text from the receipt image and stores it in the household account book app's database (DB) . If you want to enter more detailed information , you can directly take a picture of the purchased product that matches the receipt and store it additionally .
All saved information is encrypted to prevent personal information leakage , and only when the user consents is the data in the smartphone app DB transmitted to the main system DB of the household account service . Personal information is also de-identified and encrypted during this process , so sensitive personal information is not included in the main system DB . Users can enter data into the household account book not only by taking pictures , but also by voice input or direct typing , and can automatically receive information through electronic receipt linkage and approval procedures with the payment company .
This service allows for much more detailed accounting management than a general household account book , and the user interface is conveniently designed in the form of a familiar household account book . The dashboard allows you to easily understand your current financial status by comparing your daily expenses with the previous day , and comparing weekly , monthly , and yearly changes and the previous week , month , and year . When setting goals , goal achievement analysis information is also provided .
The entered receipt information is mapped to product information by item , and if the actual purchased product and the receipt contents are different , a warning is displayed so that the user can correct the error . There is also a product capacity difference and price comparison function , so that you can prevent purchasing errors or overspending . The price comparison service is available through paid membership or separate credit payment , and you can check for purchase abnormalities by comparing it with existing receipts , or you can analyze repeat purchase patterns to receive recommendations for related products .
Over time , based on accumulated purchase data , AI provides product recommendations , group purchase notifications , new product information , etc. , and also supports cost comparison and creation of optimized purchase lists through a pre- purchase simulator . When shopping online , it analyzes multiple shopping malls to provide the optimal purchase list , and automatic purchase information can also be received through system linkage with affiliated shopping malls .
Purchase information saved in the household account book can be used as legal evidence in the event of a product recall or accident . A cloud backup service is provided to membership members . Backup is possible in various ways, such as through smartphones , PCs, and USBs . Personal information protection is enhanced through password settings . If the password is lost , it can be reset through the app . A 10GB free backup cloud service for one year is also provided to prevent damage to users .
The main system of the household account service analyzes de-identified user household account data , collaborates with product providers , and contributes to inventory control and price discounts through regional statistical analysis . In addition , half of the profits generated by selling competitive products and user purchase statistics to companies are reflected in product discounts , allowing users to receive products at lower prices .

1. Differentiating Points
- Diversity of input methods and level of automation Existing household account book apps mainly focus on automatic linking of card and bank statements , character recognition , and manual input . On the other hand , AI household account book services support a much wider range of input methods, such as taking pictures of receipts , adding product photos , voice input , and linking electronic receipts . Users can choose the most convenient method depending on the situation , and AI OCR automatically extracts and matches receipt and product information, dramatically reducing the burden of input .

If there is a mismatch in product capacity , quantity , or image , it immediately issues a warning, allowing you to manage incorrect purchases or mistakes . This is a precise consumption recording method that is hard to find in existing services .
- Strengthened data security and personal information protection All data is encrypted and stored within the smartphone and cannot be transmitted externally without the user's explicit consent . Only de -identified information is stored in the main system, minimizing the risk of personal information leakage . Security features such as blockchain- based data integrity and password settings for cloud backup have also been further strengthened .
- The real-time price comparison and group purchase linked
membership service compares online and offline prices of the same product in real time and even provides group purchase and discount information by region . Unlike existing apps that stop at simple consumption analysis , this is a practical function that allows you to experience actual savings .
