AI Log Analyzer (MVP)

A minimal log analysis system that stores logs, groups recurring ERROR events deterministically, and generates on-demand AI summaries.

Overview

• Stores logs from multiple services
• Groups recurring ERROR logs deterministically
• Generates AI summaries only when requested

Design

• INFO / WARN → stored as logs
• ERROR → grouped into error groups
• AI explains error groups, not individual logs
