-You can create a _log anomaly detector_ for each log group. The anomaly detector scans the log events ingested into the log group and find anomalies in the log data. Anomaly detection uses machine-learning and pattern recognition to establish baselines of typical log content.
+You can detect anomalies in your log data in two ways: by creating a _log anomaly detector_ for continuous monitoring, or by using the [anomaly detection](./CWL_QuerySyntax-Anomaly.html) command in CloudWatch Logs Insights queries for on-demand analysis.

+A log anomaly detector scans the log events ingested into a log group and finds anomalies in the log data automatically. Anomaly detection uses machine-learning and pattern recognition to establish baselines of typical log content. For on-demand analysis, you can use the `anomaly detection` command in CloudWatch Logs Insights queries to identify unusual patterns in time-series data. For more information about query-based anomaly detection, see [Using anomaly detection in CloudWatch Logs Insights](./LogsAnomalyDetection-Insights.html).
