The Short Answer

WhatsApp now has two reminder features, and neither one nudges a chosen person at a chosen time. Since January 2026 you can create an event in a group chat and set a custom early reminder, so everyone invited gets a ping before it starts. Separately, long-pressing any message gives you Remind me, which resurfaces that message for you after 2 hours, 8 hours, 24 hours or a time you pick. There is no way to say "remind Priya at 9am on Monday to submit her form", no repeating group reminder, and no way to add a reminder bot to an ordinary group: Meta's Groups API is limited to Official Business Accounts and caps a group at 8 participants. What works instead is reminding the person rather than the thread. NagMeLater's groups are a name list: you create one, the other person joins with a 6-character code, and "remind @Priya on Monday at 9am to submit her college application" fires on Priya's own WhatsApp.

What WhatsApp Itself Offers Inside a Group

Three separate things get called "group reminders", and it is worth knowing which one you actually found.

Event reminders (real, and genuinely useful)

WhatsApp Events live inside a group chat: a title, a date and time, and RSVPs. In January 2026 Meta announced that when you create an event you can also set a custom early reminder for the invitees, so people get nudged ahead of time rather than at the moment it starts. The same update added member tags and text stickers, and it was covered by MacRumors, 9to5Mac and TechCrunch on 7 January 2026. WhatsApp has also widened events over time: you can RSVP as "maybe", bring a plus one, give an event an end time, pin it in the chat, and create one in a one-to-one conversation as well as a group.

If what you need is "everybody in this group, remember the thing on Saturday", that is the built-in answer and you should use it. It is free, it lives where the conversation is, and nobody has to install anything.

Remind Me on a message (real, but only for you)

Long-press a message and WhatsApp offers Remind me, with 2 hours, 8 hours, 24 hours or a custom time. When the time comes, WhatsApp resurfaces that message with a reminder tag. It works in a group, but the reminder goes only to the person who set it, it needs an existing message to attach to, and it does not repeat. MacRumors' walkthrough covers the taps, and our own guide to the Remind Me feature covers what it can and cannot do.

Scheduled messages (not shipped)

A scheduled message would be the obvious way to post "submit the form today" into a group at 9am. WhatsApp is building it, tap and hold on the send button, 10 minutes to two weeks ahead, and it is expected to work in groups. As of September 2026 it has not reached beta testers for ordinary chats; the only scheduling that has is for channel admins. The dates and sources are in our guide to scheduling a WhatsApp message.

And why no bot can sit in your group

People often assume a reminder bot can simply be added to the family group. It cannot. Meta's Groups API, the only sanctioned way for a business number to send into a group, is open only to Official Business Accounts and caps each group at 8 participants including the business itself, with no endpoint to add a participant. That is built for a small support thread, not a 60-person class group. So any product promising reminders inside your existing WhatsApp group is either using an unofficial client, which risks the ban, or describing something else.

Which leaves the approach that does work: forget the thread, remind the person.

How NagMeLater Does It: Groups, Codes and @Aliases

A NagMeLater group is not a WhatsApp group. It is a small list of names and numbers that lets you address one person by alias. Nothing is posted anywhere; each reminder arrives as a private message on the recipient's own WhatsApp.

  1. One person creates a group and gets a 6-character invite code.
  2. Others join by texting that code to the bot with the name they want to be called.
  3. Any member can then remind any other member by alias.

Here is the whole flow, from both phones.

Two details in that last bubble are worth pointing out, because they are the two things people ask first. The reminder says who set it: the copy is literally "Reminder from Dad", with the group name in front of it. And it arrives from the bot, not from Dad, so Priya is not answering her father at 9am; she can just do the thing. From the moment it is set, the reminder is between Priya and the bot, and Dad only hears the outcome.

That outcome is the part that saves a phone call. When Priya replies done (or taps it, or replies to the reminder itself), Dad gets one line saying so. If an hour passes with no reply and no snooze, he gets one line saying she has not confirmed yet. Never both, and never more than one per reminder. If he would rather not hear either, reports off stops them for every reminder he sets, and reports on brings them back. Each person can have up to five reminders reporting back to them at once.

Who Actually Uses This

Families

Parents nudging teenagers who ignore phone calls. "remind @Rohan tonight at 10pm to take his medication" arrives on Rohan's phone at 10pm, and nobody has to stay awake to follow up.

Small teams: accountants, recruiters, agents

Accountants chasing clients for documents. "remind @Suresh on Monday at 10am to send the Form 16" lands when Suresh is most likely to be at his desk. The CA workflow post goes deeper on the filing-season version of this.

Event coordinators

"remind @Caterer on Friday at 2pm to confirm the final headcount." The caterer is in the group, the reminder fires on time, and the WhatsApp thread stays empty until there is something to actually discuss. For the wider job, see event planning on WhatsApp.

Business partners

"remind @Ankit every Monday at 9am to share the weekly report" sets a recurring reminder that keeps going without anyone chasing it.

Managing the Group

Three commands cover the housekeeping, and they are the ones the bot lists under help groups.

There is no member limit in the bot, and you can belong to several groups at once. If two groups contain different people using the same alias, the bot says so and asks you to name the group rather than guessing which person you meant.

One more thing worth knowing: a reminder somebody else set for you is never paused by our quiet-period rules. Our own reminders back off if you stop replying for a while, because every message costs us something and silence usually means the chain has stopped being useful. A reminder that came from a person in your group is exempt from that, because it is not ours to quieten.

Before You Start: Three Honest Limits

Both people have to have messaged the bot. Joining the group counts, and it is one message, so the setup is about thirty seconds per person. But you cannot remind a number that has never said anything to NagMeLater, and that is on purpose: nobody should get an unsolicited automated message because a stranger typed their number.

The recipient needs their own access. A reminder for another person runs on that person's account, so they need an active free trial or a plan of their own. If they do not have one, the bot tells you plainly that their trial has ended rather than silently dropping the reminder. Creating the reminder is also recorded against both accounts, yours and theirs, so a group reminder is not a way around anybody's trial.

It is not a group chat. Reminders go to one named person at a time. If you want the whole thread nudged, use WhatsApp's own event reminder, described at the top of this page. If you want the whole thread nudged about something that is not an event, the honest answer today is that you send a message and, if you want to be sure you remember to send it, schedule that nudge to yourself.

Everything else behaves like an ordinary reminder: cancel, edit and snooze work the same way, and recurring schedules repeat until somebody stops them.

Frequently Asked Questions

Does WhatsApp have group reminders?

Partly. Since January 2026 you can create an event in a group chat and set a custom early reminder for the invitees, which nudges everybody who was invited before it starts. You can also long-press any message and pick Remind me, but that resurfaces the message for you alone. WhatsApp has no way to send a reminder to one chosen person at a chosen time, and no repeating group reminder.

Can I add a reminder bot to my WhatsApp group?

No. Meta's Groups API, the only sanctioned way for a business number to send into a group, is restricted to Official Business Accounts and caps a group at 8 participants including the business number itself, with no way to add participants through the API. Anything advertising reminders inside your existing 50-person group is either using an unofficial client, which risks your account, or describing something else. NagMeLater reminds each person in a private chat instead.

Can I send a WhatsApp reminder to someone who does not use NagMeLater?

They join your group first, which takes one message: they text the NagMeLater number 'join AB3C7X as Priya' with your code. No app to download and no account to create. After that you can remind them by alias, and they need their own active trial or plan for the reminders to fire.

Do group reminders count against my trial or subscription?

The reminder runs on the recipient's account, so they need their own active trial or plan. Creating it is recorded against both accounts, yours and theirs, so setting reminders for other people is not a way around anybody's trial. If the recipient's trial has ended, the bot tells you so instead of quietly dropping the reminder.

Can the recipient see who set the reminder?

Yes. A group reminder arrives as '📌 [FamilyGroup] Reminder from Dad:' followed by the task, so the recipient always knows which group it came from and who set it. It still arrives from the bot rather than from your own number, so there is no conversation to answer at 9am.

Will I know if they actually did it?

You will know whether they said so. When the person replies done to a reminder you set, you get a one-line confirmation with the time they replied. If an hour passes with no done and no snooze, you get a one-line note that they have not confirmed yet. It reports their reply, not the deed itself, so it works best for people who will answer honestly. Send reports off to stop these updates, reports on to restart them.

Can I set recurring group reminders?

Yes. 'remind @Ankit every Monday at 9am to share the weekly report' repeats exactly like a personal reminder. Daily, weekly, monthly and interval schedules all work. The reminder lives in the recipient's list, so they can see it and cancel it from their own phone.

How many groups can I create?

There is no hard limit. You can create several and be a member of several at once. If the same alias exists in two of your groups and belongs to different people, the bot asks which group you meant instead of guessing.
