Text Diff Tool

The Text Diff Tool computes precise differences between two input texts. It accepts two strings, normalizes options (case sensitivity, whitespace handling, diff mode), and returns a structured diff. It supports line-level, word-level, and character-level comparisons to match user intent.
The primary users are writers, software engineers, technical editors, and researchers who need to verify edits, track changes, or align versions without re-reading entire documents.

Under the hood, the tool implements a Myers diff-based algorithm to identify minimal edit sequences. It can produce a unified view (contextual insert/delete blocks) or a side-by-side representation highlighting changes. Outputs include a summary, a list of edits with location and type, and an export-ready diff in a machine-readable format.
The tool emphasizes deterministic results, reproducible patches, and clear provenance for each change, which is essential for audits and compliance in documentation workflows.

Unique value includes precise token-level control, configurable diff granularity, and robust handling of large texts. It suits version control workflows, content localization, and documentation audits. Scenarios include comparing product specs before release, verifying translation updates, and auditing policy changes. Diff results can be consumed by downstream AI agents for patch generation, patch verification, or automated review.
