feat: Add External Calendar Export / Sync Functionality (.ics/Google Calendar)

📝 Feature Description

While StudyPlan excellently extracts deadlines and tasks from unstructured text internally, users lose out on ecosystem-wide push notifications and system widgets.

Adding an External Calendar Integration / Export feature would allow users to push their newly generated AI study plans directly into their daily personal workflows (Google Calendar, Outlook, Apple Calendar).

💡 Proposed Solutions

• Option A (Universal): Add an "Export to Calendar" button on the UI that generates and downloads a standard .ics (iCalendar) file payload containing all the extracted deadlines.
• Option B (Advanced Integration): Provide an OAuth connect toggle option for Google Calendar API to automatically sync events into a separate secondary study calendar.

🛠 Impact & Value

• Retention: Users are more likely to use the tool if it integrates seamlessly with the calendar ecosystems they already track.
• Automation: Completes the "automated deadline manager" promise by removing the final manual step of copying dates over.

🏆 Contribution & Assignment Request

I am a contributor looking to implement this feature. I have reviewed the repository architecture (Vanilla JS + Express + SQLite) and believe I can tackle this.

Could you please review this request and assign it to me?

Hi @thakurakanksha288

I'd like to work on this feature. I have reviewed the proposed changes and would be happy to implement the analytics dashboard, including the backend API endpoint, database queries, and frontend integration.

Could you please assign this issue to me?

Thank you!

Hi @maintainers,

I would like to work on this feature under GSSoC 2026.

I have experience with JavaScript, backend integration, and productivity-focused web applications. After reviewing the proposal, I understand the goal is to extend StudyPlan beyond internal task management by enabling users to export study schedules into their existing calendar ecosystems.

My proposed approach would be:

• Implement support for generating standard iCalendar (.ics) files from extracted deadlines and study tasks.
• Add an "Export to Calendar" action within the task/dashboard interface.
• Ensure generated events contain proper titles, descriptions, due dates, and metadata.
• Support compatibility with Google Calendar, Apple Calendar, Outlook, and other calendar applications through the universal .ics format.
• Keep the implementation lightweight and independent of third-party OAuth requirements.
• Structure the code so future Google Calendar synchronization can be added without major refactoring.

I will also verify generated calendar files against common calendar clients to ensure proper import behavior and a smooth user experience.

Thank you for your consideration!
