MPS (MonoPsyches) is a terminal-based productivity system that stores tasks, notes, reminders, logs, and nested workflow structures in plain-text .mps files. It provides composable typed elements with optional arguments, hierarchical organization, natural-language date handling, full-text search, statistics, export tools, and git integration while keeping all data human-readable and portable.
