Obsidian is a love letter to plain-text, local-first knowledge management — a graph of linked Markdown files that you fully own. It's powerful and private, but it's a knowledge tool, not a productivity tool. 1plann bridges the gap: notes that connect to tasks, a calendar that shows deadlines, and AI reminders that make sure nothing slips.
