For agents and the people who run them
Escalates the way you set it. Stops when you acknowledge.
Claude Code, Cursor, or any MCP host can schedule a reminder that reaches you by email, WhatsApp, SMS or phone call, in the steps and timing you choose. No agent? Set it up yourself on the web in two minutes.

Two ways in
My agent reminds me
Your agent already knows what is happening. NudgeBell is how it reaches you when it matters: a call, a WhatsApp, an SMS, or an email, escalating until you acknowledge. The chain runs on our servers, so it keeps going after the session ends.
- →
Your monitor sees production down. Your agent calls you through NudgeBell, then calls again if you do not press 1.
- →
A long build or eval finishes at 3am. Your agent sends a WhatsApp, then rings you if you do not tap it.
- →
Your agent spots a domain or certificate expiring next week. It books a chain for the day before.
- →
A pull request has waited on your review for two days. Your agent texts you, then calls.
- →
Anything else your agent can notice. It decides what matters. NudgeBell makes sure you hear about it.
I remind myself
Birthdays, renewals, tax deadlines, medication. Add it once on the web, pick the channels in order, and NudgeBell escalates until you acknowledge. No agent, no download, nothing to keep running.
Set your first reminder →For people who work with AI agents
Let your agent remind you.
Claude Code, Cursor, or any MCP host can create escalating reminders for you. Tell your agent “call me on Friday at 9am if I have not renewed the domain” and it schedules the whole chain through NudgeBell.
The reminder fires from our servers, not from the agent. Close the laptop, end the session, go offline. The phone still rings.

Any agent
Claude Code, Cursor, any MCP host, or your own code over the REST API.
Runs on our servers
Nothing to install, nothing to keep running.
Same escalation
Up to 5 steps, any channel in any order, and it keeps going until you acknowledge.
How it works
Set it once. We handle the rest.
Step 01
Add what you want to remember
A birthday, a renewal, a deadline. Give it a title and a date.
Step 02
Pick a channel
WhatsApp, SMS, email, or a phone call. Whatever you're most likely to see.
Step 03
Live your life
We'll nudge you on the day, where you're already looking. You won't miss it.
One product, every kind of reminder
Different things, different channels.
You pick what fits.
Birthdays & anniversaries
Days ahead, so you have time to plan the gift, the reservation, the flowers.
Subscription renewals
Heads-up three days before the charge. Cancel it, keep it, or decide.
Medication & health
For you or someone you care for. The nudge that actually lands, every time.
Tax & deadlines
Filings, submissions, consequences. The ones you cannot afford to miss.
Client follow-ups
The deal went cold because you forgot to reply. Not again.
School & kids
Parent-teacher meetings, fees, activities. Right before you walk out the door.
Loan & bill payments
Every payment, every month, on time. No surprise late fees.
Document renewals
Six months out. Passports, visas, licenses. Before they ruin the trip.
Travel & check-in
Check-in windows, hotels, insurance. The details that make or break the trip.
Want it louder?
Build a chain
Most reminders only need one nudge. But for the ones you truly cannot miss. Stack channels in any order, with your own delays between each step.
Example chain: you pick the channels and set the gaps
Send on the day at 9:00 AM
If no response in 8 hours
+8 hours later
If no response in 12 hours
SMS
+12 hours later
If no response in 6 hours
Phone call
+6 hours later
Stops the moment you acknowledge. No further nudges.
Don't take our word for it
People who kept forgetting, finally stopped.

One missed renewal pays for a year of NudgeBell.
