FAQ
Do you build voice agents or just text chatbots?
Both. I build text chatbots (website/WhatsApp/Messenger) and full AI voice agents that make and take phone calls using Vapi, Retell or ElevenLabs.
Which AI voice do you use?
I use ElevenLabs for natural, human-like voices on Standard and Premium — it's the best-sounding option available. Lower-cost voices (OpenAI TTS, Deepgram) are available if you want to reduce running costs.
Are you locked to one platform?
No. Vapi, Retell and ElevenLabs Agents each have strengths — I recommend the best fit for your use case, budget and call volume.
Will the bot use my own business information?
Yes — Standard and Premium train the assistant on your documents, FAQs, and website so answers are accurate and on-brand.
Can it book appointments into my calendar?
Yes. Premium connects to Google Calendar / Calendly and your CRM so bookings happen automatically.
What do you need from me to start?
Your goals, FAQs/docs, preferred channels, and API access (I'll guide you — it takes minutes).
Do I need paid OpenAI / Vapi / ElevenLabs accounts?
Yes, those run on your own accounts so you own everything. I'll help you set them up and estimate monthly costs.
Do you provide support after delivery?
Premium includes 7 days of post-delivery support; extended support is available on request.
