If your AI receptionist is not capturing complete details, such as full names, phone numbers, or addresses, you can improve accuracy by updating the prompts in your call flow. This is called prompt tuning.
Prompt tuning helps make your questions clearer and more specific, so callers know exactly what information to provide.
When to use prompt tuning
You may want to update your prompts if:
The AI is receiving incomplete names (e.g., first name only)
Phone numbers are missing digits
Addresses are incomplete
Callers seem confused by a question
How to update your call flow detail prompts
Step 1: Open the Joist app
Step 2: Select the AI Receptionist. You will find the AI Receptionist tab on:
Web: the left-side menu bar, then click AI Receptionist, and click Go To Your Assistant
iOS: click More in the bottom right corner of your page, and then click AI Receptionist from the list
Android: click Manage in the bottom right corner of your page, and then click AI Receptionist from the list
Step 3: From the main screen, click Visit this Page on the Make Changes tab
Step 4: Select Test AI Receptionist
Step 5: Use the navigation at the bottom of the page and click Next (twice) until you get to the call flow prompt page titled “Here’s the information AI Receptionist will collect from customer calls”
Step 6: From the list of detail prompts, click on the one you want to edit and make your changes
Step 7: Save your changes
