[Reservation and Meeting Confirmation Directly from Phone Calls] Autonomous Phone AI Agent "SupaDen" Now Includes Scheduling Functionality in Standard Plan - General Availability Begins

Kaitaku Co., Ltd. (Headquarters: 19-6 Nakamachi, Shinjuku-ku, Tokyo / Representative Director: Tomonori Matsuki) will begin general availability of its phone AI agent "SupaDen" on March 19, 2026, with the addition of an automatic scheduling function that integrates with calendars in its standard plan.

With this new feature, the standard plan will allow for the immediate confirmation of schedules during calls, both for incoming and outgoing calls, without the need for transfers or callbacks. The AI will resolve inefficiencies in the field, such as "received a call but the person in charge was unavailable, so a callback was necessary" or "scheduling a meeting required multiple calls."

Background of the Release

"The phone was answered, but the schedule couldn't be set" - Lingering Inefficiencies in the Field

While many tasks are becoming automated with the spread of AI and various tools, scheduling appointments that start with phone calls still often relies on human intervention.

・When a customer calls to request a reservation or meeting, a callback is necessary if the person in charge is unavailable.

・When trying to make an appointment by calling out, the back-and-forth of scheduling takes a long time to finalize.

・Only a limited number of staff members can confirm the person in charge's calendar while handling calls.

In response to these challenges, the previous standard plan of SupaDen offered automatic handling of incoming and outgoing calls. With the addition of this new feature, it is now possible to automate the entire process, from real-time calendar reference during a call to immediate schedule confirmation.

1. Features Available on All Plans

The moment an outgoing call is completed, the call content is automatically posted to a Slack channel specified by a Webhook URL. This eliminates the need for staff to manually transcribe notes, allowing the entire team to grasp the response content in real-time.

Three Key Points of the Scheduling Function

1. Completion of Scheduling for Both Incoming and Outgoing Calls: Whether receiving a customer's call or making an outgoing call, the AI naturally handles scheduling within the flow of the conversation, confirming reservations and appointments on the spot. This eliminates the need for "I'll check with the person in charge and call you back."

2. Real-time Calendar Integration: The AI integrates with Outlook Calendar and references the availability of the person in charge in real-time, proposing and booking the optimal schedule without conflicts.

3. Easy to Start Using with Low Implementation Hurdles: Existing features such as bulk outgoing calls via CSV upload, automatic saving of call records, and integration with Slack/Teams remain, with the addition of the scheduling function.

Main Use Cases

[Use Case for Incoming Calls]

For inquiries from customers and business partners, the AI handles initial reception and confirms meeting or business negotiation schedules on the spot. This allows for capturing reservations without opportunity loss, even when the person in charge is unavailable or during busy hours. It can be utilized in all industries where reservations and appointments are handled, such as healthcare, beauty, real estate, legal services, and SaaS customer success.

[Use Case for Outgoing Calls]

For follow-up calls to dormant or prospective customers, the AI handles the entire process from contact to schedule confirmation. This streamlines operations by allowing staff to receive only high-intent appointments.
