JournalLeaflet
Read the writeup →A digital notebook for capturing thoughts in seconds — typed or spoken — organized into notebooks you can lock, encrypt, and share. The idea came because I wanted to write more. I also wanted to create a shared notebook with my wife to document the first year of our second daugther. It is possible to export (with or without voice recordings), so notes never have to stay stuck on a distant server — you'll be able to pull everything out, keep the history or drop it, and turn it into a local diary (or a book for your daughter) if you'd rather.

FinanceStegvis — My First Stock Portfolio
Read the writeup →Built from my own experience starting to invest: buy and hold, diversify to manage risk — but not enough capital to buy everything at once, so each purchase had to be whatever gave the best value that day while still fitting the plan. Stegvis picks a risk profile, builds a diversified 20-30 stock target portfolio, and shows what to buy next with whatever small amount you have to save. Not financial advice — just the concept that got me started.
