About

dialog is a high-performance desktop application for log file analysis and viewing, built with C++ and Qt6. This tool efficiently handles large utf-8 text files through memory-mapped I/O and deferred indexing, enabling fast navigation, realtime highlighting, and customizable rule-based filtering.

The application features include integrated AI analysis for contextual insights.
