Show HN: Built a an Expense Tracker with Google Document AI and Claude 3 Haiku

Hi!

More than 20-year backend dev here, trying to dive into mobile development and LLMs :-)

I’ve always wanted to explore practical use cases for LLMs and I came up with ReceiptiX. It's a simple expense tracking mobile app. I'm trying to design it to be different from other complex budgeting apps by focusing on simplicity. The main idea is to minimize manual input involved in expense tracking.

Main features: - Receipt scanning (this is where I started from) - Voice input - Telegram integration (you can send your expenses to a bot)

The app is built with Flutter and Firebase. I use Google Document AI for OCR and then send the extracted text to Claude 3 Haiku for parsing and categorization. This is cheaper than giving an LLM an image as is.

Right now I’m struggling a lot with traction. ASO is a nightmare :-) I think the niche I chose is very saturated, which was probably my biggest mistake. Still I want to keep going :-)

Please try the app. It’s free for the first 5 receipts. You can even delete old receipts to stay under the 5-receipt limit and use the app for free indefinitely :-)
