iMessage-exporter, a full-featured CLI app and library

I've spent a long time reverse engineering nearly every aspect of Apple's iMessage SQLite tables to build this program. As far as I know, there are no other tools that support the full corpus of iMessage features, including edited messages, app messages, reactions, and threads. I built this software to preserve some conversations with loved ones; I hope others find it useful as well. For the curious, here are some of the more interesting aspects of the database I came across: - Dates are stored as Unix timestamp with an epoch of 1/1/2001 00:00:00 - Messages can have multiple parts,…

In plain words

iMessage-exporter is a command-line tool and library that extracts and preserves iMessage conversations from Apple's database. It supports edited messages, app messages, reactions, and threaded conversations by reverse-engineering iMessage's SQLite structure. The tool is designed for users who want to archive and export their message history, particularly for personal preservation purposes.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... Girl with a pearl earring: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... I integrated this new InstructPix2Pix model into imaginAIry (python library) so it's easy to use for python developers.

  • The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

  • Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
