Why this helps
A surprising number may reflect a data issue rather than a real business change.
- Catch unusual values before meetings
- Use a repeatable review prompt
- Keep the result in your chosen report channel
Setup
Build it in a few focused steps.
- 1Connect Google Slides and ClickHouse in Notis once.
- 2Create an automation named deck anomaly check.
- 3Tell Notis to accept slide text and metric context from a webhook, then query ClickHouse for unusual values and summarize evidence.
- 4Choose a Notis webhook trigger and select where run reports go.
- 5Test by sending one real slide context payload.
Questions about this workflow
What does the webhook need?
Provide the slide context, metric name, and any table or date details available to you.
Can it detect anomalies without a baseline?
It can use the comparison logic in your instruction, but a baseline or time window must be supplied when ClickHouse cannot infer one.
