Kaggle Datasets

Kaggle started as a machine learning competition platform and grew into one of the largest open collections of datasets. Members upload data on everything from film ratings to satellite imagery, usually with a description, a preview, and often a few community notebooks showing how to load and explore it.

You can download datasets directly, pull them through the Kaggle API, or work with them inside Kaggle's free hosted notebooks. Files are typically CSV, JSON, or SQLite, so they are easy to drop into a pipeline. For RAG, Kaggle is most useful as a discovery layer: search a topic, find a dataset someone has already tidied up, and reuse the accompanying notebooks to save yourself the cleaning work.

Licences vary from dataset to dataset, so check the terms on each listing before you build on it. Quality varies too, since anyone can upload, but the community ratings and usage counts give you a quick sense of what is worth your time.
