Clean data by talking, not typing code.
Get a messy real-world dataset and an AI agent that writes and runs Python for you. Your job is to think like a data scientist: find the problems, ask the right questions, and fix the data.
A data science contest where your thinking is what counts
Nobody wins by typing faster. You win by spotting what's wrong with the data and knowing how to fix it.
Plain-language commands
Type "fill missing ages with the median" and the agent turns it into working pandas code.
Your own private sandbox
Every participant gets an isolated cloud computer with the dataset loaded. Nobody else can touch your data.
Charts on demand
Ask for histograms, bar charts or scatter plots and see them right inside the chat.
Fair and cheat-proof
The agent only does what you ask. Requests to reveal answers or bypass the rules are blocked.
Timed sessions
You have 60 minutes. A live timer and action counter keep you on track.
Instant AI scoring
When you're done, an AI judge reviews your whole session and gives a score out of 100 with feedback.
