About NudgeBell

NudgeBell sends reminders through the channels you choose, in the order and timing you set, and stops once you acknowledge. Options are a phone call for things that must land, WhatsApp, SMS and email for low-stakes items, and the escalation chain runs on its servers, so it continues after an agent session ends.

It is built for AI agents and the people who run them: an agent running in Claude Code, Cursor or another MCP host can schedule a reminder, for example a call when production goes down that repeats if you do not press 1, a WhatsApp when a long build finishes at night, or a text and call about a pull request waiting for review. People without an agent can set reminders for birthdays, renewals, tax deadlines or medication on the web in about two minutes, with no download. The site has how-it-works, use cases and pricing pages.
