Understand

Get answers, not exports

Claude reads the totals and writes the summary staff actually need.

Product features

Everything an academy runs on. Plus the tools that build it.

Daily operations in Monster SaaS, product work in DevOps, and public-data and education tools around them.

Attendance

Mark attendance in one tap

Scheduled, present, late, absent. Every change reaches the dashboard and the make-up list.

Practice rooms

Fill rooms, not spreadsheets

Hourly occupancy, overlap checks and booking rules for every room and branch.

Settlement

Close payroll with confidence

Calculate, adjust with a reason, approve and lock. Every change is logged.

Specs · DevOps

One source of truth

Screens, flows, events and the data model stay linked, with a map that lays itself out.

QA · DevOps

Tests that keep up

Test cases move from draft to approved, and flag themselves when the spec changes.

API health · DevOps

Know before users do

DNS, connect, TLS and response checks with uptime bars, incidents and reports.

Public data · API Checker

Find APIs that really work

A 200 response isn't enough. API Checker tells real data apart from empty or error payloads.

AI Lounge

AI classes near you

Five media centers, 50 courses and every notice, in one public site.

Lectures

From first prompt to automation

Beginner lectures on vibe coding, public data, n8n and cloud, built around one running example.

Real screens

See the products. Data blurred for privacy.

Revenue · 12-month trend per branch, manual entries, CSV

Consultations · unified inbox

Students & guardians

Screens use demo data. Names, contacts, amounts and project content are blurred.

Monster AI · powered by Claude

Ask your academy. Keep the product organized.

Claude connects Monster SaaS and DevOps. Staff get plain answers about their day, and the product team gets specs and tests that stay current.

Most are Friday violin lessons. Studio 2 is free on Saturday mornings.

Plain answers from your own numbers.

Claude reads counts and totals from Monster SaaS, never names or phone numbers, and answers in the words staff use.

  • Weekly summaries for directors
  • Reply drafts for parent inquiries
  • Flags for unusual payroll changes
  • Spec, test and release drafts in DevOps

People approve. Everything Claude writes lands in DevOps as a draft. A planner or QA lead approves it, and revision checks stop a draft from overwriting newer edits.

Organize

Specs from feature docs

Turn Monster SaaS feature docs into DevOps features, events and exceptions.

Organize

Drift check

Compare the spec with real routes and tables, and list what's missing.

Quality

Test case drafts

Draft QA cases for booking conflicts, payroll locks and attendance changes.

Operate

Incident summaries

Explain what failed, when and why, from DevOps health checks.

Operate

Release notes

Turn a history compare into notes for staff and a changelog for developers.

Optimize

Academy insights

Spot make-up backlogs, full rooms and unusual adjustments from totals.

Assist

Reply drafts

Draft answers to parent inquiries from schedules and policies.

Organize

Data summaries

Group failed API checks by cause for the education team.

Safe and affordable by design

  • Drafts only. Claude never approves its own output.
  • Typed output. Every draft is checked against the DevOps schema.
  • Through the API. Roles and revision checks still apply.
  • No personal data. Prompts get counts and totals, not names.
  • Low cost. Cached spec export, nightly batches at half price, effort set per task.
  • Traceable. Each call is logged with token usage next to the change it produced.

FAQ

Questions, answered.

What does 뮤몬스터 make?
Five products: Monster SaaS for music academies, DevOps for product teams, API Checker for public data, the Modu AI Lounge website, and the AI Lab lecture program. Claude connects Monster SaaS and DevOps.
Who is Monster SaaS for?
Music academy directors, branch managers, front-desk staff and teachers. It covers the dashboard, students and guardians, lesson calendar, attendance and make-up lessons, practice rooms, revenue, teacher settlement and consultations.
Can one account run several branches?
Yes. A branch switcher at the top applies to every page. Pick one branch or see all branches together.
How is personal data protected?
Student and guardian contact details stay on the server. Dashboards and Claude get counts and totals only. The academy is always taken from the signed-in session, never from the request.
What does Claude do, exactly?
Claude writes drafts: spec and test drafts in DevOps, weekly summaries, release notes and reply drafts. A person approves each one before it's used.
Can other teams use DevOps?
Yes. DevOps keeps one workspace per project for screens, flows, events, data model, QA, issues, documents, schedules and API health, with company SSO and project roles.
Can you build something custom for us?
Yes. We build operations software, public-data services and Claude features to spec, with design documents first and automated tests before release.
