Rocket.Chat Receipt Processor App

We’ve all wasted hours squinting at crumpled receipts and battling spreadsheets. With the AI Receipts Processor, manual expense tracking becomes obsolete. This app transforms piles of receipts into organized reports with AI-powered precision.

Features 🚀

• Scan and store expense data from receipts sent via images
• Data can be grouped according to user by using channels or threads
• Create comprehensive reports segmented by categories and time periods
• Support custom LLM selection
• Detect and block malicious prompt injection

How to set up 💻

1. Have a Rocket.Chat server ready. If you don't have a server, see this guide.
2. Install the Rocket.Chat Apps Engine CLI:

npm install -g @rocket.chat/apps-cli

Verify if the CLI has been installed:

rc-apps -v

3. Clone the GitHub Repository:

git clone https://github.com/RocketChat/Apps.Receipts.Processor.git

4. Install app dependencies:

cd Apps.Receipts.Processor/app
yarn install

5. Deploy the app to the Rocket.Chat server:

cd app
rc-apps deploy --url <server_url> --username <username> --password <password>

or

make deploy url=<URL> username=<USERNAME> password=<PASSWORD>

• If you are running the server locally, the default server_url is http://localhost:3000.
• username is the username of your admin user.
• password is the password of your admin user.


6. Open the App Settings by navigating to Administration > Marketplace > Private Apps. You should see the app listed there. Click on the app name to open it, then go to Settings and add your LLM provider configuration.
