FAQ
What can your AI voice agent do?
It can handle calls, answer questions, qualify leads, book appointments, update CRM/database records, use custom tools, retrieve business information, and perform other actions based on your workflow.
Do you build custom solutions or use no-code tools?
I build custom-coded AI systems using Python, FastAPI, APIs, webhooks, databases, and voice platforms such as Vapi. The solution is tailored to your business rather than being limited to a generic template.
Can you build a custom dashboard?
Yes. I can build a custom admin dashboard for managing call data, transcripts, leads, analytics, and other agent-related information, reducing your dependence on third-party dashboards.
Can you integrate the agent with my existing tools?
Yes. I can integrate your agent with CRMs, calendars, databases, REST APIs, webhooks, and other business systems, depending on your requirements.
Can the AI agent use my company’s knowledge?
Absolutely. I can integrate your business documents, FAQs, and knowledge base using RAG so the agent can provide more relevant and context-aware responses.
Can you build both inbound and outbound voice agents?
Yes. I can develop inbound or outbound agents for use cases such as reception, sales, lead qualification, customer support, reminders, and appointment management.
Will you provide the backend and integrations?
Yes. Depending on the project scope, I can build the custom backend, database, webhooks, API integrations, business logic, deployment, and supporting infrastructure required for your AI voice system.
