Zaro summarize
Zaro is where you can build working software from your scattered work. Everything you know is spread across Gmail, Slack, notes, and tabs that don't talk - Zaro pulls it into one place and lets you build apps from it in minutes: your research, your side projects, your plans, your decisions. Then they keep themselves updated, checking your connections every day so you don't have to. No code. No maintenance. No graveyard of prototypes you started and never finished.
