Text-Snippet-Summarizer

Extract structured, concise summaries from news headlines and brief texts using pattern matching and LLM interactions.

This package helps researchers, journalists, and analysts quickly categorize and understand complex domain-specific issues (e.g., environmental crises, economic policies, geopolitics) by summarizing raw textual snippets. It avoids processing full documents, multimedia, or URLs, focusing on rapid, structured insights for decision-making or reporting.
