Euphony

Euphony is an innovative visualization tool designed for AI engineers and teams working with chat data and Codex logs. It transforms complex Harmony JSON/JSONL conversations and CLI session logs into interactive, filterable timelines that can be browsed directly in the browser. This makes debugging and analyzing AI workflows more intuitive and accessible, especially for those building on gpt-oss models or managing multi-turn conversations. By providing a clear visual representation of AI interactions, Euphony helps streamline troubleshooting, performance tuning, and workflow optimization. Its focus on interactivity and ease of use sets it apart, enabling teams to quickly identify issues and understand AI behaviors without sifting through raw log files.
