อ่านเฉพาะข่าวสำคัญจากครู — ส่งตรงให้คุณ ไม่ต้องเลื่อนสติ๊กเกอร์ทั้งวัน
Problem
ในไลน์กลุ่มผู้ปกครองมีคน 30+ ส่งสติ๊กเกอร์รูปลูกตลอด ครูแจ้งวันสำคัญ ค่าเทอม ค่าเครื่องแบบ — เลื่อนหาทั้งวันก็ยังหาไม่เจอ. I'm at work and can't keep scrolling LINE all day, but I can't leave the group either.
Audience
Thai working parents (mostly moms 28-45) of kids in Anuban-Mor6 schools (3-18) who must stay in the school's LINE group (90%+ of TH schools use LINE as the only channel) but cannot babysit it during work hours. Especially first-time parents and single moms without grandparent backup.

- SIG-20260426-sea-mainland-family-logistics-line-group-noise: "ใครเบื่อกลุ่มไลน์ผู้ปกครอง / สติ๊กเกอร์ขยะดันประกาศสำคัญจนมองไม่เห็น" — top-tier RECURRING Pantip pain, 5+ threads
- SIG-20260426-sea-mainland-family-logistics-school-event-outfit-stress (overlap): event dress-codes posted in LINE 2-3 days ahead, parents miss them
- SIG-20260426-sea-mainland-family-logistics-school-expense-tracker (overlap): school-fee announcements in LINE drowned in stickers
What we ship
**Core features (MVP)**
- "KruBot" forward-bot in LINE: user forwards (or auto-forwards via LINE Notify) school chat — bot filters only teacher/admin messages, drops stickers/photos/spam
- Auto-extraction: dates (Thai พ.ศ. 2569 → 2026), payments (with PromptPay QR if present), dress-code (color of the day, e.g. Mother's Day blue), homework deadlines, "what to bring"
- 06:30 daily digest: "📌 Today: blue uniform + jasmine flower / 📅 Tomorrow: tuition 2,500 THB by Apr 30"
- "Confirm received" — parent taps tick in digest; virtual read-receipt sent to teacher automatically (optional)
- Family share: one account, two parents see the digest; for mixed families a TH/EN translation toggle
**Primary user flow**
1. Thai landing, hero "อ่านแต่ข่าวสำคัญจากคุณครู" — sign up via LINE Login
2. User adds KruBot to school LINE chat as silent listener (or forwards manually)
3. Bot learns over 24h — shows "this is what we think important", parent labels 5-10 examples for calibration
4. Post-calibration — daily digest delivered on LINE + email
5. Free tier: 1 school chat + 7-day history. Pro 99 THB/mo: up to 3 chats (kids in multiple clubs), unlimited history, EN translation, multi-parent share
**What it looks like**
- **Landing**: hero "เลื่อนน้อยลง รู้มากขึ้น" + before/after screenshots (LINE flooded with stickers → clean digest), social proof "200+ parents using", CTA "เพิ่ม KruBot ฟรี"
- **Main screen**: hierarchical list — Today / This Week / Upcoming / Past; each item tagged 💰payment, 🎨dress-code, 📚homework, 🎉event, 📅field-trip; tap → original Thai + EN translation
- **Output**: 06:30 morning push in LINE: "🔔 1 new from KruBot: bring 850 THB camp fee by May 8 (PromptPay 081-xxxxxxx — Kru Suphaphan)"
**MVP build plan (10 days)**
- Day 1-2: backend User + LINEChannel + Message + ExtractedEvent, LINE Login + Bot setup
- Day 3-5: Claude-based Thai NLU pipeline (importance classifier + date/fee/dress-code entity extraction)
- Day 6-7: digest generator + LINE/email delivery cron, OCR pipeline for teacher screenshots
- Day 8: PromptPay via Omise, Pro-tier paywall
- Day 9-10: Thai landing, deploy, Pantip family forum + Facebook BKK Working Moms launch
Reasoning
SIG-line-group-noise documents this as a top-tier pain: 5+ Pantip threads with mass complaint, direct ask "อยากได้ช่องทางที่กรองสติกเกอร์". The category is critical — 90%+ of Thai schools use LINE as the only channel, and parents cannot leave. This is an **inbox-cleaner for LINE**, not a school-system replacement — which removes the key adoption blocker (teachers don't have to change anything).
Stack-fit is ideal: a forward-bot via LINE API is a standard pattern (the Thai LINE OA-bot ecosystem is huge). Thai NLU via Claude is a standard API call, ~$0.001 per family per day. Stripe is not needed — TH cards are rejected; PromptPay via Omise.
Business model is strong: parents-with-kids-in-school is an annual subscription pattern (low churn through the school year), with multi-child upsell (Pro tier for 3+ chats).
Quick competitive read
- **LINE OpenChat / LINE Notify** — free native tools, only generic notification (no extraction/filter). Parent bottling = standard workaround, no AI.
- **Schoolbright / Edsy / SchoolMaid** — TH school ERP with push notifications, but (a) school must buy, (b) teachers don't bother, (c) doesn't work over existing LINE groups.
- **Generic Thai LINE filter bots (เห็ดบอท etc.)** — hobby projects, keyword-only, no school context.
- **Beeper / Texts.com** — multi-messenger inbox, no semantics.
- **White space**: AI-powered LINE school filter with Thai NLU + structured digest. Competitive pressure 7/10.
Initial pricing hypothesis
Free tier (1 chat, 7-day history) for virality; Pro 99 THB/mo (3 chats + EN translation + family share + unlimited history). Family pack 199 THB/mo for extended families (5 chats — many clubs/curriculum tracks). One-time "exam season pass" 199 THB/term for Mor.6 exam-prep families.
Distribution hypothesis
1. Pantip thread "กรองข้อความครูใน LINE — เครื่องมือใหม่" — viral demo (before/after)
2. Facebook Bangkok Working Moms (60K), Bangkok Maths Tutor Moms, Singha Park Family — community DMs with 7-day free
3. TH Twitter — short Thai reels about "สติ๊กเกอร์ฝังประกาศ"
4. School-specific sub-LINE OpenChats for parents (Anuban Samsen, Mater Dei, etc.)
5. PR in Mother & Care, Modernmom, parenting blogs
