Why Choose ToDoS?

Unlike traditional to-do apps, ToDoS uses Natural Language Processing (NLP) to extract dates, priorities, tags, and recurrence instantly. Stuck on a big task? Click the sparkles icon to invoke AI that breaks your work into actionable sub-steps. Your data stays yours all stored locally in LocalStorage with zero server-side tracking.

Core Features

• Smart Task Input – Use @ for dates, ! for priorities, # for tags, * for recurrence (e.g., “Finish report @tomorrow !high #work *daily”)
• AI Task Breakdown – Click the sparkles icon to intelligently decompose complex tasks into actionable sub-steps via OpenRouter API (supports GPT-4, Claude, Gemini, etc.)
• Focus Mode – Built-in 25-minute Pomodoro timer with customizable duration; your top task auto-pins for deep focus






• Insights Dashboard – Track productivity streaks, daily completion rates, priority distribution, and identify your “Focus Peak” day
• Calendar View – Visual monthly overview of your workload; switch between list and calendar layouts instantly






• Secure & Private – Uses Vercel Serverless Functions (BFF pattern) to securely proxy AI requests; your API key never touches the browser
• Offline-First Architecture – All task data persisted to LocalStorage; works without internet connection (AI features require network)
• Keyboard Shortcuts – Global hotkeys ( / , i, t, f, s, b, Esc) accelerate workflows for power users
