Field notes
The homepage separates features labeled available now from a roadmap: scheduled checks can run every 5, 15, 30, or 60 minutes, with alerts by email, Discord, Slack, or a custom HTTP endpoint. Its current recording scope is deliberately narrow—the first spoken response only—while full transcripts, scenario tests, and turn-by-turn speech latency are marked coming soon. The page shows an in-progress test-call interface, but the supplied extract does not establish a live account's results.
