Base Chat, a newly launched cloud service building on an existing open-source product, offers an intuitive way to interact with company knowledge bases by using advanced multimodal retrieval technology from Ragie, similar to that used in projects like JFK Files and Mearsheimer.ai. This platform integrates with various data sources such as Google Drive, Notion, and JIRA, and allows users to choose from AI models by Anthropic, Open AI, and Meta, providing personalized experiences with custom prompts and avatars. Administrators can manage user interactions and create public chatbots for sharing knowledge externally. Ragie customers can connect their data with Base Chat, enabling a conversational interface for data queries and the development of custom applications. The service is priced at $18 per user monthly, with different data plans and optional audio and video features available on a pay-as-you-go basis.
