Private test build

MinSim

Build interactive software-training simulations — screenshot → hotspot → narration → play.

Open the builder

Everything runs in your browser. Save/load your work as a .json file — nothing leaves your machine.

Open the Builder →

Optional: the screen recorder (Chrome)

A Chrome extension that captures a real web workflow into MinSim steps — pixel-perfect screenshots + exact hotspots. It downloads a recording-*.json you drop into the builder with ↑ Load.

↓ Download the recorder
  1. Unzip it, then open chrome://extensions
  2. Turn on Developer mode (top-right)
  3. Click Load unpacked → pick the unzipped minsim-recorder folder
  4. Pin it, record a workflow → it downloads recording-*.json
  5. Back in the builder, hit ↑ Load and pick that file
It's a developer-mode install (not the Chrome Web Store), so it needs those few clicks once. Voice generation is off in this test build — the player narrates with your browser's built-in voice.
