• 🔔 Socket.IO (real-time presence, notifications & signaling for SecureDrop)
• 🤖 Hugging Face Inference API (AI Summarizer integration)

🗄️ Data & Caching:

• 📦 Convex built-in DB
• 🔄 @tanstack/react-query (data fetching & caching)
• 📅 date-fns (date utilities)

🚀 DevOps & CI/CD:

• 🌐 Vercel (hosting & auto-deploy)
• 🤖 GitHub Actions (build → lint → test pipeline)

🧪 Testing & Quality:

• ✅ Jest + React Testing Library (unit & integration tests)
• 🔍 ESLint (code quality) + 🎨 Prettier (formatting)
• 🔐 TypeScript (static type safety)

SecureDrop enables:

• Peer-to-peer chat: Send messages directly to other users without the server storing message content.
• File transfer: Exchange files securely between peers, with status tracking (sending, sent, received).
• Serverless signaling: Uses Socket.IO to establish peer connections.
• TURN support: Ensures connectivity behind NATs/firewalls using Metered.co TURN servers.
• Secure & private: Only the peers involved in a session can access messages and files.

This feature integrates seamlessly into the existing chat interface.

AI Summarizer enables:

• Summarize long chat threads into 2–4 sentences.
• Highlight key decisions and action items automatically.
• Works in real time using Convex Actions + Hugging Face models.
• Breaks long conversations into chunks for accurate summarization and merges results into a single concise output.
