Question: I'm looking for a platform to build conversational AI chatbots that can integrate with multiple interfaces and support various languages.

If you're looking for a conversational AI chatbot that spans multiple interfaces and supports multiple languages, ChatBotKit is a good all-purpose platform. It lets developers and nondevelopers create AI chatbots that span multiple interfaces like Slack, Discord and WhatsApp. The platform supports multiple languages and comes with a variety of foundation models from companies like OpenAI and Anthropic. With tools like a coding assistant, custom datasets and integrations with popular chat apps, ChatBotKit is good for a variety of use cases like AI experiences, AI personas and AI support.

Another good option is the Microsoft Bot Framework, an open-source foundation for building enterprise conversational AI. It taps into Azure Cognitive Services for sophisticated natural language understanding and generation abilities. Among its features are a visual authoring canvas, custom language understanding models and integration with speech recognition and synthesis services. It's good for building virtual assistants, customer care and enterprise applications, with the flexibility to control data security and management.

It supports more than 100 languages, customizable conversation flows and integration with helpdesk and CRM systems, making Quickchat AI good for automating customer support, sales and eCommerce tasks. The service offers several pricing tiers and a 7-day free trial to let you try it out.
