• Employees - Get answers to HR questions without waiting for someone to respond
• Admin Teams - Keep calendars and emails organized without losing your mind

The Problem We’re Solving

Let’s be real—traditional HR workflows are painful:

• Scheduling is a nightmare - Back-and-forth emails to find meeting times
• Finding policies takes forever - Employees get frustrated waiting for answers
• Communication breaks down - HR teams and employees aren’t on the same page
• Repetitive tasks kill productivity - Same forms, same confirmations, over and over
• Tools don’t talk to each other - Calendar, email, and docs all in separate silos

Intelligent Chat Assistant

Just chat with the AI. Ask it to schedule interviews, find policies, or generate HR documents—it understands context and responds naturally, like talking to a colleague who actually knows HR inside and out.

Google Calendar Integration

Your calendar becomes intelligent. It finds time slots, detects conflicts before they happen, and sends invitations automatically—no more “does Tuesday work for you?” emails.

Gmail Integration

Stop writing the same confirmation emails. The system generates them automatically, uses smart templates for different scenarios, and keeps everything organized so you’re never scrambling to find an important message.

Smart Form Generation

Need a document generated? Just describe what you need. The system creates the right forms with the right fields, custom-tailored to your request.

Policy & Information Access

Employees don’t need to dig through docs or ping HR. They chat with the AI, ask questions, and get accurate answers about policies and procedures instantly.

Unified Dashboard

Everything in one place. Pending tasks, scheduled meetings, active conversations—one clean interface gives you complete visibility into all your HR operations in real-time.

Frontend

Built with Next.js 15 for speed, TypeScript to catch bugs before production, Tailwind for styling that doesn’t slow things down, shadcn/ui for components that actually work, and Lucide icons that look clean everywhere.

Backend & AI

Next.js API Routes power the backend, Prisma handles the database cleanly, LangChain orchestrates the AI magic, Groq provides lightning-fast model inference, and JWT keeps sessions secure.

Google Workspace

Tapped into Google Calendar API for meeting magic, Gmail API to handle emails automatically, OAuth2 for authentication that companies trust, and Google Cloud for the rest.

Data & Tools

SQLite in development (with PostgreSQL for production), Zod for runtime type checking (catch errors early), and Bun as the package manager because it’s just faster.

Complex AI Integration

Getting LangChain to work smoothly with multiple AI providers was tricky—ensuring consistent responses and keeping context intact. I solved it with robust error handling, smart retries, and a modular architecture that keeps everything maintainable.

Securing Google APIs

OAuth2 is straightforward until it’s not. I had to handle token refresh, secure credential storage, and manage flows across Calendar, Gmail, and other services. Built an authentication system that handles it all automatically.

Real-time Calendar Sync

Timezones are a nightmare, calendar conflicts sneak up on you, and keeping everything synchronized bidirectionally is complex. I created utilities that parse dates intelligently and detect conflicts before they become problems.

Keeping Everything Type-Safe

With TypeScript, Zod, and complex nested data structures from external APIs, ensuring type safety at every layer took careful architecture. It’s worth it though—caught bugs early and made refactoring painless.
