## What it does

Visual Sentinel gives an AI assistant tools to check website availability, DNS records, TLS certificates, and loading speed. Ready-made prompts guide checks for site health, troubleshooting, and domain launch preparation. The service also monitors visual changes and content updates.

Public checks work without credentials. Account actions, including monitor management, incident history, and alert acknowledgement, require `VS_API_KEY`; keys are available on Business and Agency plans. Without one, the assistant can still run the public checks, but cannot use account tools.

## When to use it
- inspect DNS records for a domain
- check when a TLS certificate expires
- measure a site's loading speed
- trace a possible website failure
- review incidents and unacknowledged alerts

## Example prompts
- Check the availability, DNS, SSL, and speed of `example.com`.
- Investigate which layer may be causing trouble on `example.com`.
- List my monitors that are currently down.
