Deep Service Report

Overview and Core Technology

Tanka represents a significant advancement in AI-assisted team collaboration, directly addressing the problem of “Organizational Amnesia” that plagues many businesses. Inspired by decades of neuroscience research, Tanka’s proprietary Memory Knowledge Graph and Multi-Agent Framework transforms scattered communications into a structured, evolving knowledge base. Unlike conventional AI assistants that forget past interactions, Tanka remembers and contextually retrieves critical workplace knowledge, ensuring seamless collaboration across teams and empowering informed decision-making. The system learns from user interactions and business context, creating an adaptive memory layer that grows more valuable over time.

Key Features

AI Long-Term Memory: Tanka’s standout feature is its ability to transform unstructured data from conversations, emails, and documents into an organized, accessible knowledge repository. This memory system retains institutional knowledge even when key employees leave-acting as a personalized work memory bank that captures achievements, insights, decisions, and tasks. Smart Reply: Based on analysis of conversation context, team structure, and business history, Tanka generates tailored responses for both messages and emails. This feature saves significant time in drafting communications and reduces repetitive typing. Users can also provide brief ideas that Tanka expands into fully crafted messages. AI Assistant: Beyond storing information, Tanka actively supports teams by summarizing threads, surfacing insights, setting reminders, and suggesting next steps. This assistant can pull information from both internal memory banks and external sources without requiring users to leave their chat environment. Universal Communication Hub: By integrating with various platforms (Slack, WhatsApp, Telegram, Gmail, Outlook, calendars, and Notion), Tanka creates a centralized communication system that synchronizes messages, schedules, and knowledge across platforms-reducing the need for constant context-switching.

Market Impact and Reception

Since its alpha pilot launch in October 2024, Tanka has attracted over 1,000 teams to its waitlist within just five months. Early users have sent over 35,000 AI-generated smart replies, reportedly saving an estimated 111 workdays of effort. The company officially launched on February 18, 2025, backed by Shanda Group, a global investment firm that operates the Chen Institute (TCCI)-a research institute focused on bridging human cognition and artificial intelligence.

Security Framework

Tanka is built with enterprise-grade security, featuring multiple protection layers including:

Encryption at rest using AES-256 and in transit using TLS 1.2+
Strict data isolation between organizations
Zero data retention by third-party Large Language Models
A commitment that user data is never used for AI model training

Country

Tanka is headquartered in the United States, with offices located at 303 Twin Dolphin Drive, #6054, Redwood City, California 94065.
