KartikChugh/Otto — reverse-engineered prompt

Build me a friendly web app called Otto that helps beginners do machine learning by chatting in plain English.

I want someone to be able to type things like “I want to label flower species by petal length” or “detect fraudulent credit card activity” and have the app figure out whether that sounds like classification, regression, or language analysis. Then it should guide them through choosing a dataset, recommending a model and useful preprocessing, and explaining the choices in simple words instead of jargon.

It should work well for people with little or no ML background, include a few sample datasets so they can try things instantly, and also let them describe their own data. I’d like clear visualizations for sample data, a simple neural network builder for more advanced cases, and support for language tasks like sentiment and entity extraction.

Please make the experience feel conversational and educational, with generated Python code and helpful annotations shown in the browser. If anything is unclear, check the current docs or the project site and match that experience closely.
