Hi HN, I'm Lucas. I mostly build XR things, but over the past month or so I've been developing a tool that became necessary for me: I'm usually working on many different things at once, and I needed a way to create reports and check what I worked on last year on a specific day.

mydev.day is an automatic development diary that writes itself as you build. You connect your agent to it once per project (takes a couple of minutes), and from then on it automatically adds an entry per feature. After that you can query it via the API to ask anything about all your work across projects and accounts, or go to the app to print nice looking charts and reports.

It started as an internal tool, but inspired by the indie hackers I follow, I decided to turn it into a product to see if it could be helpful for other builders and developers out there!

Fun fact: it was really cool to dogfood it on itself as I built it!

Luckas, good job. In simple terms, what's the core problem? Who did you create reports for? Yourself or your employer?

If yourself, how big is this problem?
