PlanItOut

A calendar that thinks for you.

Comment

Inspiration

We all use calendars, but none of them actually help us decide what to do first. During busy weeks, sorting dozens of tasks becomes its own task. We wanted a tool that removes the mental load entirely, something that organizes your schedule for you.

What it does

PlanItOut is an AI-powered smart calendar that automatically sorts, prioritizes, and schedules your tasks. You add tasks through a simple form or by chatting with the assistant. The AI analyzes the task, predicts its importance, estimates the time required, and fits it into your day. With one tap, your task list transforms into a fully optimized calendar, clear, organized, and ready to follow.

How we built it

We built a full-stack web app with:

  • React and Tailwind for the frontend UI
  • OpenAI API for natural-language task analysis and prioritization
  • A custom scheduling algorithm that arranges tasks based on importance, duration, and deadlines

Challenges we ran into

  • Designing a scheduling system that feels natural and avoids conflicting tasks
  • Getting the AI to infer priority correctly from short descriptions
  • Passing structured task data cleanly between the form, AI, and calendar UI
  • Making the interface simple and intuitive while still feeling powerful

Accomplishments that we're proud of

  • Creating an AI-first calendar that feels genuinely helpful
  • Clean UI with one-click AI sorting and smooth animations
  • Accurate task prioritization from natural-language input
  • A polished prototype built in under 24 hours

What we learned

  • How to prompt AI for structured outputs
  • How to design scheduling logic around urgency, importance, and duration
  • Better React state management under rapid iteration
  • How to integrate AI into real-world user workflows

What's next for PlanItOut

  • Real-time notifications and reminders
  • Adaptive AI that learns user habits
  • Integration with Google Calendar and other platforms
  • Voice-based task entry
  • A mobile app version
  • Productivity analytics and streak tracking
