Frequently Asked Questions

What log types are supported?
Apache Spark, Java/Spring Boot, and generic application logs. Auto-detect picks the best mode from your paste.
Is my log sent to a server?
For AI-enhanced analysis, log text is sent to our API. Instant analysis uses local pattern matching. Redact secrets before pasting.
How is this different from Spark Error Explainer?
Log Analyzer supports multiple log types (Spark, Spring, generic) with auto-detect. Spark Error Explainer is Spark-only.
Does it work without AI?
Yes. Instant analysis always returns structured root cause and fixes even when AI capacity is busy.
