SimuLab is here
Published on August 5, 2026
For months SimuLab was the missing piece of the cycle. Reading with Theca, remembering with EON and explaining with Imagine already worked; practising was still pending. As of today SimuLab is open to every account at simulab.noxdragon.com.
What it does
- Problems built for you. Pick a topic and SimuLab writes the problem. If you would rather start from your own material, it can pull them from the books you already keep in Theca.
- Scenes that move. Many problems come with an interactive 2D or 3D scene inside the statement. You can rotate it, move it and watch what changes. Understanding a problem no longer depends on picturing it in your head.
- Hints when you get stuck. Ask for a hint and SimuLab nudges you towards the path without handing over the answer.
- Four ways to answer. A number, multiple choice, a written answer, or a step-by-step solution. Each one is graded on its own terms.
- Grading that explains. It is not a plain right/wrong: you get a score and written feedback telling you what worked and what was missing.
- Collections and the Market. Organize your problems by subject or by exam, and publish a collection for others to use, or clone someone else's.
What it means for the other apps
SimuLab closes the cycle. A book you uploaded to Theca can end up as a sourced summary, a deck of cards in EON, and a collection of problems in SimuLab, without typing anything twice. All on the same account and the same plan.
Where to start
The SimuLab documentation covers everything from your first problem to the language used to describe scenes. And if you would rather poke around before reading, open the app and create a problem on any topic: it is the fastest way to see what this is about.
