Sumy is a Python library and command-line utility for automatic extractive summarization of plain text documents and HTML pages. It implements multiple summarization algorithms (LexRank, LSA, TextRank, Luhn, Edmundson) with multilingual tokenizer support and a simple evaluation framework.

Use cases

• summarize long articles into key sentences
• extract summaries from HTML web pages
• summarize text in multiple languages
• evaluate summarization quality against reference summaries
• add extractive summarization to a Python application
• quickly condense a Wikipedia page from the command line

When to choose

• you need lightweight extractive summarization without GPU or deep learning models
• you want a CLI tool for quick one-off summarization of URLs or text files
• you need support for many natural languages including Czech/Slovak
• you want a simple, dependency-light Python API for summarization

When to avoid

• you need abstractive summaries that rewrite text in new sentences
• you need state-of-the-art neural summarization quality
• you need to summarize very long documents beyond its design scope
