Sketch

If you've ever asked a generic AI assistant to help with pandas code, you know the pain — it has no idea what's in your DataFrame, so the suggestions often miss the mark on column names, types, or quirks in your actual data. Sketch is an AI code-writing assistant built specifically for pandas users that understands the context of your data, which dramatically improves how relevant its suggestions are.

It's usable in seconds and doesn't require adding a plugin to an IDE, so there's nothing to install or configure before you get value. Under the hood, Sketch uses efficient approximation algorithms (data sketches) to quickly summarize your data and feed that information into language models — it summarizes columns and writes these summary statistics as additional context into the code-writing prompt, so the AI sees your data, not just your question.
