Agent Sonic
Automatic WhatsApp Group Reminders: Never Nag the Group Again
Quick answer: You can automate recurring WhatsApp group messages with an AI assistant added to the group. Tell Agent Sonic once — "post 'timesheets due today' in the team group every Friday at 10" — and it posts on schedule, forever. No one has to be the group's human alarm clock anymore.

Every group has an unpaid project manager
In every WhatsApp group there's one person who remembers: who posts "standup in 10", who chases the timesheets, who reminds everyone the rent is due. That job has no title and no salary, but it has a real cost — and when that person is busy or on holiday, the whole group's rhythm slips.
The tasks themselves are trivial. The problem is that they recur, and humans are bad at recurring.
Schedule the message once, let it post forever
With Agent Sonic in the group, the recurring message becomes a one-time instruction: "Every weekday at 9:25, post 'standup in 5 minutes'." "On the 1st of each month, remind everyone rent is due." "Every Wednesday at 19:00, post that practice is tomorrow at 18:30."
Sonic posts on time, every time — daylight saving included. The group stops depending on anyone's memory, and the person who used to do the nagging gets to just be a member again.
Where this pattern shines
Work teams: standup nudges, timesheet deadlines, end-of-sprint reminders, "send your weekly summary" prompts. Shared flats: rent, bills, cleaning rotations. Clubs and hobby groups: practice schedules, game-day logistics, equipment reminders. Family: the weekly call with grandma, whose turn it is to host dinner.
The common thread: a message everyone needs, on a schedule nobody wants to own.
Beyond the broadcast
Group reminders are the start, not the whole story. The same assistant handles your personal reminders and to-dos, chases individuals for answers ("ask Tom if he's joining Thursday and tell me"), reads documents, and searches the web — all from chat.
So the group gets its rhythm, and you get an assistant for everything around it.
Getting started
Add Agent Sonic to your WhatsApp group like any other contact, then tell it what to post and when — in plain language, no syntax. It confirms the schedule and takes over from there.

Frequently asked questions
Can WhatsApp send scheduled messages to a group natively?
No — WhatsApp has no built-in scheduling for groups. An assistant like Agent Sonic, added as a group member, posts your recurring messages on schedule.
Can I change or cancel a recurring group reminder?
Yes. Just tell Sonic in chat — "move the standup reminder to 9:45" or "stop the rent reminder" — and the schedule updates.
Does the whole group need to sign up?
No. One person adds Sonic to the group and sets the schedule. Everyone else just sees normal group messages.
