yolog.dev Desktop is a desktop application designed to preserve and analyze AI coding sessions that would otherwise be lost in JSONL files. It specifically works with Claude Code and similar tools to capture the complete interaction history between developers and AI assistants.

The application offers session replay functionality with full playback controls and keyboard shortcuts for navigation. It provides comprehensive search capabilities across all sessions with full-text search and highlighting. Users can analyze their coding patterns through metrics including token usage, cost tracking, time spent, and productivity insights with features like vibe metrics, flow detection, and streak tracking.

The tool operates through auto-sync functionality that watches designated folders for new session files and indexes them automatically. It uses a local-first approach where all data remains on the user's machine without cloud dependency.

Benefits include the ability to review debugging sessions, track coding decisions made with AI assistance, and monitor project costs over time. The cinematic mode provides immersive full-screen playback for reviewing lengthy sessions.

The product targets developers using AI coding assistants like Claude Code, with support for more tools planned. It's built as a local desktop application that works offline without requiring signup, storing data locally using SQLite.
