Questions & Answers

As answered by people managing SpeedCrunch and Class Cortex.

How would you describe the primary audience of your product?

Class Cortex's answer:

K-12 teachers, mainly in middle and high school (Years 5 to 10 is the sweet spot), who want a gamified classroom management system without student logins.

It suits teachers who run lessons on a projector, interactive panel or classroom TV, and schools with strict student privacy requirements, since no student data is sent to our servers. Single teachers can start on the free plan with no IT approval, and departments can share a school license.

What makes your product unique?

Class Cortex's answer:

Class Cortex combines a full classroom toolkit with a game layer in one browser tab, and students never need accounts.

  • 3D Boss Battles: the whole class joins from any device with a code and answers questions together to defeat a 3D boss on the projector, with Attacker, Defender and Support roles.
  • Persistent XP: every point counts for the student, their squad and the whole class, and the noise monitor feeds into XP automatically.
  • Privacy by design: all class data stays in the teacher's browser, so there is nothing for IT to approve.

Why should a person choose your product over its competitors?

Class Cortex's answer:

Most teachers juggle separate tabs for a timer, a noise meter, a name picker and a quiz game. Class Cortex puts them in one dashboard, with persistent XP tying them together.

  • vs ClassDojo and Kahoot: no student accounts and no student data on our servers.
  • vs Classroomscreen: the same everyday tools, plus XP, squads, Boss Battles, a seating chart and a full whiteboard.
  • vs Classcraft: XP, HP, Boss Battles, squads and badges, plus a noise monitor, seating chart and training games.

The free plan is permanent, not a trial, and it runs on the projectors and smart TVs schools already have.

What's the story behind your product?

Class Cortex's answer:

Class Cortex was built by Chris Migliore, a Digital Technology teacher in Western Australia who has taught since 2012. He was juggling five browser tabs every lesson: a timer here, a noise meter there, a name picker somewhere else.

So he built one dashboard for all of it, tested it with his own classes, and added the part his students love most: 3D Boss Battles, where the whole class teams up to take down a boss on the projector. Class Cortex launched in April 2026 and is still built and maintained by Chris as a solo developer.

Which are the primary technologies used for building your product?

Class Cortex's answer:

  • Vanilla JavaScript, HTML and CSS (no framework)
  • Three.js for the 3D Boss Battle bosses
  • PeerJS (WebRTC) for live Boss Battles and whiteboard collaboration
  • Fabric.js for the whiteboard
  • jsPDF for PDF export
  • Cloudflare Pages and Workers for hosting and licensing
  • Lemon Squeezy for Pro payments
