Simple pricing
One topic, two tiers, no surprises
Sentinel watches your topic across public RSS sources, ranks it, and sends a one-sentence take plus five headlines to your inbox every weekday. Starter is free forever; Pro unlocks the custom sources and the hour-of-day you actually read.
Pay once with any card. Your Pro tier activates the moment checkout completes — no subscription, no auto-renew.
Slack delivery is genuinely not wired yet — Pro lands on email-only today. You will get a dedicated note the day Slack ships. Reply to your Pro welcome email if you would like priority access.
