Build a branded AI chatbot that qualifies leads, answers customer questions, collects requirements, and hands conversations to your team.

  • Website visitors cannot quickly find the right service, product, or next step.
  • Support staff repeatedly answer common questions while high-value requests wait.
  • Generic chatbot tools do not follow your qualification rules or connect cleanly with your CRM and support process.
  • Conversation data is not captured in a structured way your team can act on.

FAQ

Questions clients usually ask

How is a custom AI chatbot different from a chatbot plugin?

A custom chatbot is designed around your conversation goals, data, integrations, qualification rules, escalation process, and reporting instead of a fixed plugin workflow.

Can the chatbot capture and qualify leads?

Yes. It can collect structured requirements, score or route the lead, update a CRM, notify the right person, and offer an appropriate next step.

Can it transfer a conversation to a person?

Yes. Human handoff can use email, CRM, helpdesk, WhatsApp, or another channel, with the transcript and collected details included.

Can you add the chatbot to an existing website?

Yes. We can integrate with an existing React, Next.js, WordPress, WooCommerce, or other website after checking the deployment and security requirements.

How do you prevent incorrect chatbot answers?

We use clear instructions, approved knowledge when needed, refusal and escalation rules, output testing, logging, and human review for sensitive workflows.

Can the chatbot support multiple languages?

Yes, where the selected model and your approved source content support those languages. We validate important language and handoff cases before launch.
