Hey HN -- thanks for showing interest in this. Happy to collaborate on this project. I'm hoping to get it stable soon so my own family can start using it.
I've been working on this for about 10+ years, nights and weekends. It's been really slow going since I only have my own personal data to test it with.
I just don't love that my data is primarily stored on someone else's computer up in the cloud. I want my own local copy at least. And while I can download exports from my various accounts, I don't want them to just gather dust and rot on my hard drive.
So, Timelinize helps keep that data alive and relevant and in my control. I don't have as much worry if my cloud accounts go away. Hopefully you'll find it useful, and I hope we can collaborate.
(PS. I'm open to changing the name. Never really liked this one...)
