Hana: Empowering Teams withIntelligent AI Assistance
Developed by Hanabi Technologies, Hana is an AI-powered virtual teammate that integrates seamlessly with Google Workspace, using advanced RAG for knowledge recall and LLMs for contextual responses to streamline workflows and decision-making.
A Flagship Product Built for Impact
Launched as our flagship product, Hana addresses the need for efficient team collaboration in fast-paced environments. It functions as a 24/7 assistant, handling tasks like reminders, automations via Zapier, multilingual chats, image/PDF Q&A, and shared memory from sources like Google Docs, Jira, and Confluence.
Built as a multi-tenant product, Hana combines Google Chat, approved workspace knowledge, conversational workflows, administration, and production operations.
This case study highlights how we engineered Hana as a grounded AI product rather than a standalone chatbot demo.
