# ExisEcho - Fuzzy Logic Deduplication System

> ExisEcho is the world's most flexible and fastest fuzzy logic based deduplication system. Find duplicates in any data source with advanced matching algorithms.

## What is ExisEcho?

ExisEcho is a powerful duplicate detection software that uses fuzzy matching algorithms to find similar records in your data. Unlike exact matching, fuzzy matching can identify duplicates even when there are typos, abbreviations, name variations, or formatting differences.

## Key Features

- **Trigram Similarity Scoring**: Advanced algorithm that compares text patterns for accurate matching
- **Jaro-Winkler Algorithm**: Optimized for short strings like names and codes
- **Phonetic Matching**: Finds matches that sound alike (Smith = Smyth)
- **Configurable Preprocessing**: 11+ options including synonym expansion, title removal, case normalization
- **Multiple Data Sources**: Excel, CSV, SQL Server, PostgreSQL, MySQL, SQLite, and more
- **Cross-Source Matching**: Compare records between two different data sources
- **High Performance**: Process millions of records efficiently
