Larsa AI – Built-in Call Tools

Larsa AI offers built-in “tools” that your AI assistant can use during a call. These tools help you shape the conversation flow and automate actions like transferring calls or scheduling appointments.

1. End Call Tool

Purpose: Allows the AI to politely wrap up the conversation.
How It Works: You can specify in the system prompt or logic, for example: “If the user says goodbye, end the call.”
Configuration: In the assistant’s settings, define the conditions that should trigger the end call.

2. Transfer Tool

Purpose: Moves the caller from the AI assistant to a human agent or another phone number.
Use Cases: Warm leads on a sales call, escalations in support calls, or connecting to a specific department.
Settings: In the assistant’s configuration, add the phone number or department for the transfer, and optionally include a short hold message.

3. Appointment Scheduler

Purpose: Lets the AI check your calendar availability (e.g., via Cal.com or Google Calendar) and book an appointment.
Typical Flow:

1. AI offers scheduling.

2. Caller selects a date and time.

3. AI confirms and sends a confirmation (via email or SMS if set up).

4. No-Code Automation Platform

Purpose: During or after calls, the AI can trigger actions in the automation platform (e.g., update a CRM, send an email, or log data in Google Sheets).
Setup: Link your assistant with the Automation tab, choose triggers (like “Call Ended” or “Customer Agrees”), and pick the action (such as sending a Slack notification or adding a row in Sheets).

5. Custom Mid-Call Tools

Purpose: Create your own custom API integrations for the AI to use during calls.
Use Cases: Checking inventory, verifying customer data, fetching real-time information, or integrating with your internal systems.
Setup: Define API endpoints, parameters, and the conditions when the AI should use them.

Note: Tools can be combined. For example, the AI can use a custom tool to check availability, then schedule an appointment, and finally transfer the call to a human agent if needed.
