Where centers lose students before lesson one

Three moments every center knows in enrollment season.

The 10 PM tuition question

Parents ask after work, when the desk is closed. By morning they've booked a test elsewhere.

The same fee table, all day

Counselors repeat fees and start dates all day instead of calling parents ready to enroll.

Asked once, then silence

A parent will “talk to the family first.” Nobody checks in, and she becomes a cold spreadsheet row.

How it works

Every message saved first, then the agent works.

Every message is kept, even when 50 arrive at once. The agent answers from your course files, books tests and passes chats to counselors.

Your counselors stay in charge

Parent wants a person? A counselor picks up.

The agent hands over when asked, when unsure, when a guardrail blocks a message, or on an urgent label. Counselors reply in the same inbox.

  • Add keywords like “refund” or “transfer class”
  • Counselors can pause the agent on any chat
  • Parents never repeat the child's details

The agent hands over when

  • The customer asks for a person
  • The agent isn't confident
  • A guardrail blocks a message
  • A label you mark as urgent
  • Your handoff keywords

Saturday 9 AM. Minh, born 2013. Can a counselor call me about the study plan?

Minh is booked for Saturday 9:00. Passing you to a counselor now.

Handed to staff: The customer asks for a person

StaffHi, Ms. Thao here. I'll call you tomorrow at 8 PM about Minh's study plan.
One parent, every app

Zalo or Messenger, it's one parent.

Each Zalo, Messenger, WhatsApp or Telegram identity attaches to one profile, so a parent returning months later doesn't start from zero.

  • Child's grade and test result stay on the profile
  • Tags like Test booked follow the parent
  • Nothing merges until staff confirm

    Security

    Your business data stays yours.

    How Ecbot guards credentials, screens messages and keeps businesses apart.

    Encrypted credentials

    Platform tokens use AES-256-GCM with versioned keys, so keys rotate without taking channels offline.

    Secrets never reach the AI

    Credentials never enter the model's context, so no prompt can pull them out.

    Guardrails in both directions

    Incoming messages are screened for scams and prompt attacks, replies for leaked data. You set the strictness.

    Workspaces and roles

    Each business gets its own workspace. Staff join by invitation with a role, checked on every request.

    Open source. Self-host it if you want.

    On GitHub under AGPL-3.0, with every Cloud feature. Your knowledge stays in your own Postgres.
