About this gig
A custom-built ChatGPT website integration from an agency starts around $3,000 and takes 6 to 8 weeks. As an AI Chatbot Specialist and Custom GPT developer, I build the same caliber of Claude API chatbot or ChatGPT API integration for a fraction of that cost and have it live within days.
Every week you run without one, visitors leave the second nobody answers. That's the real cost, not the invoice.
Free tip if your chatbot gives one-word answers, your system prompt is missing tone instructions, not facts. That single fix improves most bots overnight.
As a Chatbot Developer, I've built a GPT chatbot for website lead capture, a Chatbot developer for customer service handling refunds and order status, and a Chatbot for Real Estate that pre-screens buyers by budget. ChatGPT developer for lead generation work stays capped at 3 builds a month, premium attention over volume.
A clinic's Claude Chatbot now books 70% of appointments without staff involvement.
Tell me your site and budget range, I'll reply with a fixed quote in one message.

Google Ads: campaign structure audited and rebuilt, including accounts inactive for months.

Async by default. 24 hour first reply. Fixed scope, no scope creep.
Send your ad account and I'll flag two fixes within a day.
FAQ
What does an AI chatbot or AI agent build actually include?
You get a working AI chatbot or AI agent trained on your FAQs/data, connected to your website, WhatsApp, or Instagram, tested end-to-end, and ready to launch.
Can you connect my chatbot to a CRM, calendar, or Google Sheets?
Yes. I use n8n to connect your AI agent to tools like HubSpot, GoHighLevel, Google Calendar, or Sheets, so leads and bookings sync automatically.
Do you build AI voice agents, or only text chatbots?
Both. I build AI voice agents (Vapi, Retell, ElevenLabs) for calls and AI chatbots for website or messaging apps, depending on your package.
Can you build with Claude API instead of ChatGPT?
Yes. I work with Claude API, OpenAI, and other LLMs, and can recommend the best fit for your budget and use case during the build.
How fast is delivery, and is ongoing support available?
Basic builds typically ship in a few days. Standard/Premium timelines are set per project, and ongoing support or monthly optimisation is available after launch.
