LogSage — Paste your logs. Know what broke and why.
AI-powered log analysis for developers and small teams.

What it does
- Auto-detects Serilog, NLog, Log4Net, standard, and plain text formats
- Groups similar errors by pattern automatically
- Surfaces root causes — not just what complained, but what actually broke
- AI analysis per error group (severity, root cause, fix suggestion)
- No account needed to start — paste logs, get answers
