Inspiration

Email overload is a real problem. Important messages get buried, and responding takes time and mental effort. We wanted to build something that doesn’t just summarize emails, but actually acts like an assistant — understanding context and helping you reply faster.

What it does

Email Copilot is an AI-powered Gmail agent that:

  • Summarizes emails within a selected time range
  • Extracts key insights and priorities
  • Generates context-aware reply drafts
  • Helps users quickly understand and act on their inbox

Instead of reading every email, users get a clean, actionable overview.

How we built it

We built Email Copilot using:

  • Gmail API for fetching email data
  • A backend (Node.js / Express) to process and structure emails
  • AI models (via API) to summarize content and generate replies
  • A frontend interface (React / Next.js) for user interaction

The system processes raw email threads, cleans and formats them, then sends them to the AI model for summarization and response generation.

Challenges we ran into

  • Handling messy email threads and inconsistent formats
  • Keeping summaries concise but still informative
  • Generating replies that feel natural and context-aware
  • Managing API latency and response time

Accomplishments that we're proud of

  • Built a working end-to-end AI email agent in a short time
  • Achieved high-quality summaries that actually reduce reading time
  • Generated replies that are usable with minimal editing
  • Designed a clean and intuitive user experience

What we learned

  • Structuring input data is just as important as the model itself
  • Prompt design significantly affects output quality
  • Building AI agents requires both engineering and UX thinking
  • Real-world data (like emails) is much messier than expected

What's next for Email Copilot

  • Smarter prioritization (urgent vs non-urgent emails)
  • Personalized tone and writing style
  • Full automation (auto-draft or auto-send with approval)
  • Integration with other platforms (Slack, iMessage, etc.)
