A production-aware AI system that remembers who you are, pulls your emails and calendar automatically, and helps you manage tasks — without you lifting a finger.
Built for Google Cloud Gen AI Academy APAC 2026 | Cohort 1 Hackathon
Cortex is different from every other AI assistant because it's persistent. While ChatGPT and Claude forget everything after each conversation, Cortex builds a living model of you — your projects, your people, your commitments — and uses that context to actually manage your work.
The moment it clicks:
You open Cortex, and before you even ask anything, it says: "Good morning. You have 3 meetings today, 2 emails need attention from last week, and you promised Rahul a follow-up on the investment terms — that's 4 days overdue."
That's not a chat response. That's a chief of staff who actually knows you.

Every conversation updates Cortex's memory of you. It stores facts, preferences, relationships, and commitments — and surfaces them at exactly the right moment. Not just today's data. Everything you've ever told it.
One message triggers multiple specialized agents working in parallel:
- Cortex Coordinator — understands intent, orchestrates everything
- Memory Agent — retrieves and stores your personal context
- Task Agent — manages your task list with priorities and deadlines
- Scheduler Agent — reads your calendar, checks availability
- Email Agent — searches your inbox, drafts responses
Before any external action — sending an email, creating a calendar event — Cortex shows you exactly what it's about to do and waits for your approval. You stay in control.
When you sign in with Google, Cortex automatically:
- Pulls your calendar events for the next 7 days
- Imports recent emails from your inbox
- Scans emails for task-like content (deadlines, follow-ups, commitments)
- Assembles everything into your morning briefing — before you ask
Every user has their own completely separate memory, tasks, calendar, and email data. Your data is yours. No cross-contamination.

"Build a multi-agent AI system that helps users manage tasks, schedules, and information by interacting with multiple tools and data sources."
| Requirement | How We Meet It |
|---|---|
| Primary root agent + sub-agents | ✅ Cortex Coordinator + 4 sub-agents (Memory, Task, Scheduler, Email) |
| Store/retrieve structured data | ✅ Firebase Firestore with per-user isolation |
| Interact with multiple tools | ✅ Gmail API, Google Calendar API, Firestore |
| Multi-step workflows | ✅ Coordinator → sub-agent → checkpoint → execute |
| API-based system | ✅ REST API on Cloud Run |
| Automatic data pull | ✅ Gmail + Calendar pulled on Google Sign-In |
| Zero manual data entry | ✅ Sign in with Google → everything auto-imports |
- Demo mode (current): Pre-seeded data, Gmail/Calendar pull requires Firebase setup
- Production: Full Firebase + Gmail/Calendar auto-pull activates once OAuth is configured
- Mobile: Web UI works on mobile, native apps are future work
