Core Question

How to build a self-owned newsletter that curates useful deals and info for daily life?

---

What It Is

A self-hosted deal/newsletter platform that scrapes, categorises, and delivers curated information — like a personal newsletter for the family.

Key Features

• Scrapes deal pages (Jetso Club and similar sources)
• AI-powered parsing for category, date, expiry
• Smart grouping: 本週優惠 → 🔴本週到期 → 📅之後 → 📚長期 → 📋過期
• Daily digest delivery at 16:30 via WhatsApp

---

Why It Matters

• Self-owned channel — Not dependent on social media algorithms
• Family utility — Daily deals and useful info for the household
• Expandable — Can add more sources beyond Jetso Club
• AI-enhanced — Natural language categorisation and summarisation

---

Tech Stack

• Backend: Express + SQLite
• Cron jobs: Silent fetch + AI parse (668dab799896), daily notice DM (9ef98cc43243)
• Delivery: WhatsApp DM at 16:30
• Dependencies: express, better-sqlite3

• [ ] Personalised filters per family member?

Notes

• toISOString() shifts HKT -1d — use getFullYear()/getMonth()/getDate() instead
• AI parses deal pages for category, date, weekly status
• Cron runs silently; only sends daily digest
