Show HN: Quiz Coding – Teacher Mode for AI Agent in Python Notebook

3•pplonski86•1y ago
Hi everyone,

I’m working on a desktop app that helps people with domain knowledge analyze their data - even if they don’t know Python. It’s a great option for anyone who wants something more powerful than Excel or SPSS.

My cofounder and I presented our app at PyCon US’25, we have booth on StartUp Row. One of our extensions, is a chat panel next to the Python notebook, so you can just ask the AI to load your data or run analysis for you.

During the conference, a visitor (who is a lecturer) suggested a really cool idea: Instead of showing the full code, he wanted the AI to show code with a missing part. His students would then have to guess what goes in the blank. We liked the idea so much that we started building “teacher mode” right after the event!

Here’s how it works:

We updated the AI prompt so it returns code with a missing part (marked as ***). The AI also suggests three possible answers (A, B, C), and only one is correct. Our app then shows the question and three buttons. If the student picks the right answer, the full code is inserted into the notebook and runs automatically.

You can read more about Teacher Mode here: https://mljar.com/docs/ai-teacher/

And if you want to try it, you can download the app here: https://platform.mljar.com/

The app comes with Python, Jupyter Lab, and our extensions that makes data analysis much easier :)

Would love to hear your feedback or ideas!
