I built Constellation Journal because every journaling app I tried made me feel like I was filling out a form. Six weeks ago I was a field service technician with zero coding experience. I'd never written a line of code. I started learning because I had ideas I couldn't build any other way. This was built in a day, after five weeks of learning by doing. The core idea: your inner life has weight. It deserves more than a text box. So every entry becomes a star — colored by the emotion in your words, sized by how much you wrote. Real NASA data surrounds your entries. The sky starts almost entirely dark. You fill it. At 2/365 stars lit, that emptiness isn't a bug. It's the whole point. Fully local. SQLite. No cloud, no accounts, no subscription, no AI processing your thoughts. Free and MIT open source. Would love to know if it makes you want to write.
