Everything in one place
Every system you need,
nothing you don't.
Protocol replaces 8 separate apps with one unified system that knows your full context.
Daily Task OS
5 task categories, progress scoring, date navigation, tomorrow planning, and full day history with snapshots going back months.
ALTAIR AI Intelligence
Dual-model AI assistant (GPT-4.1 + DeepSeek R1) that knows your full data — tasks, history, goals, habits. Smart model routing per query type.
Revision OS
4-phase spaced repetition scheduler (1 → 7 → 21 → 31 days). Agenda, week, and month views. Overdue items carry forward automatically.
Focus OS (Pomodoro)
Precision Pomodoro timer with ambient sounds, fullscreen mode, 30-day analytics, streak tracking, and zero drift (even when the browser throttles).
Habit OS — Rituals
GitHub-style heatmaps, streak tracking, 7-day and 30-day rates, custom scheduling, and live progress rings. Integrated into the daily panel and timetable.
Timetable — TT View
Drag-and-drop 24-hour timeline. Blocks from Revision OS and Habit OS auto-populate. Resize, recolor, and print to A4 in one keystroke.
Weekly & Monthly Analytics
Stacked bar, doughnut, and multi-line Chart.js charts. Auto-generated key insights. Year-in-review timeline. Custom clickable legends with persistence.
Goal DB — Hierarchical Tree
Unlimited depth goal tree with aggregated progress, breadcrumb navigation, and cascading done-state. Half-arc gauges show overall completion at a glance.
Data Panel & Knowledge Base
5-section living knowledge base — Rules of Life, Preventive Measures, Data Drop, Specific Problems, and Visualization goals. Always readable, always editable.
