FAQs on Hiring Chatbot Developers
Should I opt for custom chatbot development or a no-code chatbot development platform?

You likely want to improve your customer engagement considerably, which is why you want to launch a chatbot. Delivering customer satisfaction often involves meeting customized and complex requirements. Custom chatbot development enables you to do that, however, no-code chatbot development platforms don’t allow customization. We recommend custom chatbot development.

Why do companies use Python for chatbot development?

Python offers many advantages to chatbot developers, e.g.: Python has extensive NLP capabilities. This open-source programming language offers comprehensive ML capabilities. You can integrate a chatbot with messaging platforms like Facebook Messenger using Python libraries. Python libraries also help Slack bot developers similarly.

Should I use a chatbot consulting and development company for complex projects?

Analyze your requirements and in-house capabilities first. Do you have complex requirements, e.g.: voice bots, integration with existing systems, managing large-scale business interactions with users of ERP systems, etc.? Do you lack in-house expertise? You should then engage a reputed chatbot development company with strong foundations and proven track records.
