I Built a Receipt-Image to JSON Converter (+ Line-Items)
Hi HN, I'm proud to show you that I've finally managed to create a Receipt-Image to JSON converter, including line-items! Over the past 10 years, I have periodically tried (every ~3 years or so) to convert Receipt-Images to JSON. What particularly interested me were the line-items. It began with a Bachelor's project where we wanted to track prices by extracting product prices from line items. However, it was not feasible to ask users to type them all into our platform. I quickly realized this process was way too tedious. Only when taking a picture is all that is required, would such a…
In plain words
A tool that converts photographs of receipts into structured JSON data, including detailed line-item information. Designed for accountants and developers building expense tracking systems, it eliminates manual data entry by automatically extracting product prices and receipt details from images. The software addresses a long-standing problem of capturing receipt data efficiently at scale.

Hi HN, I'm proud to show you that I've finally managed to create a Receipt-Image to JSON converter, including line-items! Over the past 10 years, I have periodically tried (every ~3 years or so) to convert Receipt-Images to JSON. What particularly interested me were the line-items. It began with a Bachelor's project where we wanted to track prices by extracting product prices from line items. However, it was not feasible to ask users to type them all into our platform. I quickly realized this process was way too tedious. Only when taking a picture is all that is required, would such a platform work. https://www.line-items.com is the standalone product that simply converts receipts to JSON. It's great for accountants but also for anyone building expense tracking tools. If you want to talk to me personally, send me an email. You can find it on my profile.

Hi HN! I’m proud to share that we have built a real 3rd party iMessage client for Android. We did it by reverse engineering the iMessage protocol and encryption system. It's available to download today (no waitlist): https://play.google.com/store/apps/details?id=com.beeper.ima and there's a technical writeup here: https://blog.beeper.com/p/how-beeper-mini-works. Unlike every other attempt to build an iMessage app for Android (including our first gen app), Beeper Mini does not use a Mac server relay in the cloud. The app connects directly to Apple…

Hey! I made Heynote entirely for my own use case. For many years, I always had an Emacs instance running with the scratch buffer open, even long after I had abandoned Emacs as my programming editor in favor of more recent IDE:s. The simplicity of having just one big scratch buffer appeals to me, but I still want to separate the different things I jot down somehow (without using tabs or similar). Previously, my solution was to insert a bunch of blank lines between the notes, but hitting C-A would still select the entire buffer. That's why I came up with the concept of "blocks", which turned…
