What are AI Assistants?
AI Assistants are the core of Orato. Each assistant is a fully configured voice AI that can make phone calls, receive inbound calls, or be embedded as a voice widget on your website. You configure an assistant once and it handles unlimited simultaneous conversations. Every assistant shows an estimated cost per minute - typically ~0.09/min - covering Transcriber, LLM, Voice, Telephony, and Platform costs.
Creating an AI Assistant
From the AI Assistants page, click + Create Assistant. The creation flow has three steps.Step 1 - Setup: Name & Instructions

Enter a name and select a role
Give your assistant a name (this is what callers may hear) and choose a Role:
- Web Widget - embeds on your website as a floating voice button
- Phone - used for inbound or outbound phone calls
Use the AI Instruction Generator
Fill in two fields to auto-generate your instructions:
- “What does your business do?” - e.g.
We sell CRM software for real estate agents - “Call goal?” - e.g.
