Summarizer Tool

The summarizer tool ingests English text and outputs a concise abstract that preserves core ideas. It combines extractive scoring to identify salient sentences and lightweight abstractive rewriting to improve coherence. The process emphasizes key points and reduces redundancy, making it suitable for briefs, abstracts, and study notes.
Conceptually, the tool first segments input into sentences, scores each by relevance and position, and selects a subset to form a draft. It then refines the draft to improve readability while maintaining factual fidelity. When a target length is provided, the system budgeted trimming to fit within the constraint.
The tool is useful for editors producing abstracts, researchers compiling literature notes, and students summarizing articles. It helps teams accelerate review, share core ideas, and reduce cognitive load. Optional features let you steer emphasis toward specified topics and adjust tone.
Core features include length control, optional focus topics, and export-ready plain-text outputs. Outputs comprise the final summary plus metadata such as word count and sentence count. The approach is designed to be deterministic for common domains and to gracefully handle long documents.
