ReceiptHero: A tool that uses AI to automatically identify and manage receipts

ReceiptHero is an open source receipt management application that uses Artificial Intelligence (AI) technology to help users organize various receipts. Users can upload images of receipts, and the system can automatically read the textual information in the images using optical character recognition (OCR) technology. The technology, powered by Llama 4 Scout 17B, a large language model provided by Together AI, is able to accurately extract key data from the images. For example, the system can recognize the merchant name, date of purchase, total amount, item purchased, currency type, and payment method. Once the information is extracted, ReceiptHero automatically categorizes the purchase, such as dining, shopping or transportation. To protect user privacy, all extracted data is stored locally in the user's own browser and not uploaded to a server. The project was built using a variety of modern web technologies, including the Next.js framework, the Tailwind CSS style library, and the shadcn/ui component library, ensuring an aesthetically pleasing and easy-to-use application.

Using Help

ReceiptHero is a web app whose main function is to help users scan, recognize and manage paper receipts using AI technology. It converts receipt images into structured digital information and automatically categorizes them, making it easy for users to track their personal finances. As the data is stored in the local browser, the user's privacy is well protected.

I. How to use ReceiptHero

The tool works as an online web application and requires no installation. Users can directly visit its official website www.usereceipthero.com/ to use. The basic operation process is as follows:

1. Access to the website:: Open the official ReceiptHero web site in your browser.
2. Upload receipts: There will be an upload area on the main screen of the website. You can upload your receipt images in two ways:
   • Drag and Drop Upload: Drag and drop the receipt image file from your computer directly into the upload area.
   • Click to select: Clicking on the upload area will bring up a file selection window where you can browse and select the receipt image you need to upload.
3. AI automatic processing: After uploading an image, the system's backend will automatically call Together AI's Llama model for OCR processing. This process takes a few seconds and the system will analyze the content of the image to extract key consumer information.
4. View Results: Once the processing is complete, the system displays the extracted structured data on the interface. You will see a table containing information such as merchant name, date of purchase, total amount, list of items, etc.
5. Management and analysis: ReceiptHero automatically categorizes this spending (e.g. food, transportation, etc.) and shows the distribution of your spending in a dashboard or analytics chart. All records are saved locally in your browser and you can still see the history the next time you visit.

II. Local deployment (suitable for developers)

As an open source project, if you have some development knowledge, you can also deploy ReceiptHero to your own computer or server. This allows a higher degree of customization and data control.

preliminary:

• Together AI Account: You need to sign up for a Together AI account to get the API key (API key) used to invoke the OCR model.
• Node.js environment: Make sure you have Node.js and the npm (or pnpm) package management tool installed on your computer.

Installation and operation steps:

1. Clone Code Repository:
   Open a terminal (command line tool) and usegitcommand clones the project's source code locally from GitHub.

   git clone https://github.com/Nutlope/receipthero.git
   

2. Go to the project directory:
   utilizationcdcommand into the folder you just cloned down.

   cd receipthero
   

3. Creating an environment variable file:
   The project has a file named.example.envof the example file. You need to copy it and create a file called.envof new documents.

   cp .example.env .env
   

   Then, use a text editor to open the.envfile, paste in the API key you got from the Together AI website and save the file.

4. Install project dependencies:
   Run the following command in the terminal, which automatically downloads and installs all the software libraries needed to run the project.

   npm install
   

   Or, if you use pnpm:

   pnpm install
   

5. Starting the Local Server:
   After the installation is complete, run the following command to start the development server.

   npm run dev
   

   The terminal displays a local URL, usually http://localhost:3000The

6. Access in browser:
   Open your web browser and visit the URL shown in the previous step, and you will be able to use your own deployment of ReceiptHero locally.

application scenario

1. Personal bookkeeping and budget management
   Users can upload paper receipts of their daily consumption by taking photos with their cell phones, and ReceiptHero will automatically recognize and categorize them for bookkeeping. This helps users get a clear picture of their spending habits, eliminating the need for manual input and facilitating personal financial management and budget control.
2. Corporate Employee Reimbursement
   Company employees generate a large number of receipts and invoices to be reimbursed during business trips or daily work. Employees can use this tool to quickly digitize all kinds of bills and automatically extract key information. This not only simplifies the reimbursement process, but also facilitates the audit work of financial staff.
3. Small Business Bookkeeping
   For small businesses or self-employed individuals, this tool can be used as a lightweight bookkeeping tool. By scanning daily sales tickets or purchase receipts, you can easily digitize business data for subsequent statistics and analysis.

QA

1. Is this tool free?
   Yes, ReceiptHero is an open source project, and you can use the public website it's deployed on for free, or you can download the source code and deploy it on your own server without paying anything. However, it should be noted that the Together AI service it relies on may have a certain limit on the amount of free credits, beyond which you may have to pay.
2. Is my receipt data safe?
   Very safe. According to the project, all uploaded receipt images and recognized data are stored in the user's own browser local cache and are not uploaded to the project's server for storage, which maximizes the protection of user privacy.
3. How accurate is the recognition?
   The tool uses AI OCR technology based on the Llama 4 Scout 17B model, which has a very high recognition accuracy for receipts that are clearly printed and have a standard layout. However, if the receipts are wrinkled, smudged, or have handwritten fonts, the accuracy of the recognition may be affected.
4. I'm not a developer, can I just use it?
   It is possible. You just need to visit the official website of the program www.usereceipthero.com/ You can use the core functionality directly without any complex installation and configuration.
