Frequently Asked Questions

How long does it take to build an AI agent internally?
Building an AI agent internally takes 4 to 6 months. The process spans planning, designing, coding, training, testing, and integration before deployment.
How long does it take to deploy a bought AI chatbot?
Deploying a bought and customized AI chatbot typically takes 2 to 4 weeks, depending on the level of customization required.
How much does it cost to build an AI chatbot from scratch?
Building an AI chatbot internally costs $7,500 to $20,000+ in initial build costs, $10,000 to $20,000 in operational costs, and $10,000+ in long-term investment — compared to implementation-only costs when buying.
Is it cheaper to buy an AI chatbot or build one?
Buying is approximately 10 times cheaper than building from scratch. A purchased solution incurs only implementation costs, while an internal build carries initial, operational, and long-term expenses.
What in-house expertise is needed to build an AI agent?
Building internally requires AI/ML Engineers, Software Engineers, UX Designers, and CX Specialists. Buying requires only a CX Team and a Project or Product Manager on your side.
Who manages maintenance when you buy an AI chatbot?
The vendor handles updates, support, and bug fixes. Minimal internal effort is required. Content maintenance — keeping knowledge bases and responses current — remains the customer's responsibility.
How hard is it to integrate a bought AI chatbot with existing systems?
Bought AI chatbots include pre-built integrations that typically need only minor adjustments. Integration costs are usually close to zero, compared to the complex, potentially expensive custom integrations required when building internally.
Who is responsible for security and compliance when buying an AI chatbot?
When you buy, the vendor manages compliance and security on your behalf. When building internally, you retain full control but must supply the expertise needed to meet industry standards yourself.
