Inspiration

We're all drowning in digital chaos. Between Gmail, Google Calendar, Notion, and endless notifications, we waste hours every day just trying to stay organized. We wanted to build something that actually helps an AI assistant that works for you across all your apps, but does it safely.

The big question: How do you let AI access your Gmail and Calendar without giving it your passwords? That's where Auth0 Token Vault came in.

What it does

Londoolink AI is your intelligent digital twin. It connects to your Gmail, Google Calendar, and Notion to:

Read your emails and tell you what's urgent
Check your calendar and warn you about conflicts
Generate daily briefings so you know what matters
Chat with you to answer questions about your schedule
Create Notion templates and meeting notes automatically

The magic? Your AI assistant never sees your passwords. Auth0 Token Vault holds your credentials securely and only gives the AI temporary access when needed. You stay in control.

How we built it

The Frontend (what you see)

Built with Next.js and React for a smooth, modern interface
Beautiful animations and dark mode
Simple 2-click setup to connect your accounts
Real-time chat with your AI assistant

The Backend (what powers it)

Multiple specialized AI agents working together:
- Email Agent - reads and prioritizes your Gmail
- Calendar Agent - manages your schedule
- Notion Agent - creates templates and notes
- Coordinator - decides which agent to use
Auth0 Token Vault keeps your credentials safe
PostgreSQL database for your settings and preferences

The Security

You log in with Auth0 (the same tech banks use)
When you connect Gmail, Auth0 stores the access token—not us
Our AI agents ask Auth0 for permission each time they need access
You can revoke access anytime from your dashboard
Two-factor authentication for extra protection

Challenges we ran into

1. Learning Token Vault
We started by storing encrypted passwords in our database (risky!). Switching to Token Vault meant learning a completely new way of handling credentials. It took time, but now our system is way more secure.

2. Making AI agents work together
With multiple agents (email, calendar, and Notion), we needed them to coordinate without stepping on each other's toes. We built a "coordinator agent" that figures out which agent to use based on what you ask.

3. Keeping tokens fresh
Access tokens expire after an hour. We had to make sure the AI could refresh them automatically without bothering you. Token Vault handles this for us—one less headache!

4. Giving users control
People want to choose what the AI can access. We built a consent dashboard where you can say "yes to reading emails, no to sending them." Token Vault respects these choices.

5. Deployment headaches
User data kept disappearing after updates because we were using the wrong database. We fixed the config, added automatic database updates, and created health checks to catch issues early.
