Ontoplano is a self-hosted productivity suite that unifies calendars, tasks, notes, habits, budgeting, and more into a single cross-platform application with a shared tag vocabulary. It stands out for its notebook-centric organization that groups related items (tasks, notes, bills, goals) around subjects like trips or renovations, plus optional AI integration via an MCP server. The project is open source, AGPL-3.0 licensed, and offers web, Android, and offline-first experiences with self-hosting options.

Target audience: individuals seeking an all-in-one productivity tool, self-hosting enthusiasts, privacy-conscious users
