Do you use ChatGPT? Let it reach you outside the chat.
Ask ChatGPT to text, WhatsApp, email, or call you through CallUpOnIt. Send a thought now or schedule it for the moment you need it.
Sends only to destinations you verify and enable.
CallUpOnIt queues your request and handles delivery to the destination you verified.
A queued request is not a delivery confirmation. Your agent can check its status.
The idea
Useful conversations should reach you when they matter.
Your agent writes or organizes the message. CallUpOnIt schedules and delivers it through the channel you choose.
Text & WhatsApp
A quick nudge on the phone you verified.
Longer notes and plans in your inbox.
Phone calls
A spoken reminder in the voice you choose.
Depending on your agent and channel, you can also include links, small images or PDFs, choose a call voice, and make reminders recur.
Try saying
Prompts that turn into real reminders
A little surprise
“Text me one surprising language fact this afternoon.”
Turn a curious moment in chat into a message that arrives later.
A spoken nudge
“Call me tomorrow at 7:30 AM with a short pep talk. Use the Olivia voice.”
Choose a time and one of CallUpOnIt’s available call voices.
A plan in your inbox
“Email me the packing checklist we just made on Sunday evening.”
Keep the details you worked out together where you can find them.
A weekly check-in
“WhatsApp me every Friday at 5 PM to plan the weekend.”
Recurring reminders can bring a good intention back each week.
