Skip the waiting. Let us make the call for you!
Instead of spending time calling restaurants, clinics, stores, friends, or service providers, you can ask CALL-E to handle the call for you.
It can make calls, ask questions, confirm appointments, leave voicemail messages, and report back with what happened. CALL-E is built for everyday tasks where a phone call is still faster than an email or message.

Top CALL-E use cases
1. Contacting acquaintances
Use CALL-E to pass a message, confirm plans, or coordinate with someone.
Example prompt:
“Call Jamie and ask if they are free for lunch tomorrow at 12:30 PM. If they confirm, ask if they want me to bring anything.”
Example call flow:
CALL-E: “Hi Jamie, Alex asked me to check if you’re free for lunch tomorrow around 12:30 PM.”
Jamie: “Yeah, that works.”
CALL-E: “Great. Do you want Alex to bring anything?”
Jamie: “No, I’m good.”
CALL-E: “Perfect. I’ll let Alex know.”
This is one of the strongest current consumer use cases because it helps with social coordination and simple everyday planning.
2. Leaving voicemail messages
If the person does not answer, CALL-E can leave a clear voicemail.
Example prompt:
“Call Sam and let them know their package will arrive tomorrow morning. Ask them to pick it up from the front desk.”
Example voicemail:
“Hi Sam, this is Alex’s AI assistant. Alex wanted to let you know that your package will arrive tomorrow morning. Please pick it up from the front desk.”
3. Restaurant reservations
CALL-E can call restaurants to book or change reservations.
Example prompt:
“Call Bella’s Bistro and reserve a table for 2 people on Saturday, May 16 at 7 PM. Ask for a window seat if available.”
CALL-E can also handle changes.
Example prompt:
“Call Bella’s Bistro and change my reservation from 7 PM to 8 PM.”
4. Order changes and merchant questions
CALL-E can call a merchant to check order details or request changes.
Example prompt:
“Call the bakery about order C1023. Ask them to change the frosting to half chocolate and half strawberry, and add the message ‘Happy Birthday Lily.’ Also ask if there is any price difference.”
5. Appointment confirmations
CALL-E can confirm appointments with clinics, salons, dentists, or other service providers.
Example prompt:
“Call BrightSmile Clinic and confirm my dental appointment tomorrow at 10 AM. Also ask if I need to bring anything.”
Example call flow:

Clinic: “Please bring your insurance card and arrive 5 minutes early.”
CALL-E reports the details back to you.
6. Urgent reminders for finance, gaming, or operations users
CALL-E can also support real-time reminders when a phone call is more reliable than a message.
Example prompt:
“Call me immediately if there is a transaction anomaly or account risk event.”
This is useful for financial analysts, traders, gaming operators, or operations teams who need fast phone-based alerts.

Tips for better CALL-E prompts
Give CALL-E:
1. Who to call and what number (including the country code)
2. The goal of the call
3. Key details like date, time, order number, or phone number
4. What to do if no one answers
5. What information to report back
A strong prompt looks like this:
“Call Bella’s Bistro to book a table for 2 people this Saturday at 7 PM. Ask for a window seat. Use my phone number for the reservation. If they do not answer, leave a voicemail and ask them to call me back.”
CALL-E works best when your request is specific, simple, and outcome-focused.
