yolog.dev Desktop is a desktop application designed to capture and preserve AI coding sessions that would otherwise be lost in JSONL files. It allows developers to archive their interactions with AI coding assistants like Claude Code, providing permanent access to these valuable sessions for learning and reference purposes.

The application offers comprehensive session replay functionality with full playback controls and keyboard shortcuts for navigation. It includes powerful search capabilities with full-text search and highlighting to find specific moments across all sessions. Users can analyze their coding patterns through metrics tracking token usage, costs, time spent, and productivity insights. The auto-sync feature automatically imports sessions from designated folders without manual intervention.

The application operates on a local-first principle where all data remains on the user's machine, ensuring privacy and offline functionality. It uses SQLite for data storage and automatically watches specified directories for new session files, importing them as they appear.

Benefits include never losing valuable coding sessions, being able to review and learn from past AI interactions, and gaining insights into coding patterns and costs. Use cases include debugging sessions, learning from AI-assisted coding decisions, and tracking project progress over time.

The product targets developers who use AI coding assistants like Claude Code and Cursor. It's designed for macOS desktop use with plans to support more tools in the future, operating entirely locally without requiring cloud services or user accounts.
