AI-powered knowledge tools are becoming a must-have for businesses, remote teams, employees and schools to keep track of information and find what they need quickly.

Older knowledge bases and search tools often struggle with scattered data, losing context, and slow results. This has led to the rise of advanced solutions and services like Glean, ChatGPT Teams, NotebookLM and Tanka.

Glean stands out as a leader in enterprise AI knowledge management, backed by $260 million in a funding round at a $4.6 billion valuation and trusted by 20 investors. At the same time, other tools like ChatGPT Teams and Claude Projects are also trying to tackle business problems, offering features for communication, reporting, workflows, and team collaboration support.

In this article, we’ll compare these tools and show how Tanka goes even further, offering the best solution for retaining knowledge, streamlining workflows, high performance and helping teams work better together.

Glean: AI-powered enterprise search platform

Glean is an AI-powered enterprise search tool that helps employees quickly find and retrieve key company information from various internal data sources. Using advanced natural language processing and machine learning, Glean enhances knowledge discovery across an organization's digital landscape.

Founded in 2019 by ex-Google engineer Arvind Jain, Glean has quickly become a leader in the enterprise search market. In September 2024, the company doubled its valuation to $2 billion in a new funding round, bringing its total raised to over $200 million. This significant investment underscores the growing importance and effectiveness of efficient information retrieval services in today's data-rich business environments.

The problem Glean addresses is crucial: employees can spend up to one-third of their time searching for information within their company5. This inefficiency not only hampers productivity but also leads to frustration and missed opportunities. As organizations accumulate vast amounts of data across multiple systems and platforms, the need for a unified, intelligent and accurate search solution has become paramount.

Key features of Glean enterprise search

• Enterprise-wide search: Glean connects to a wide array of applications including Google Drive, Slack, Notion, and over 100 other business tools, creating a comprehensive search index. This integration allows users to access information from multiple sources through a single interface.
• AI-driven recommendations: The platform uses AI to understand context, language, and user behavior, providing personalized search results and proactively suggesting relevant documents and conversations. This key feature helps users discover information they might not have known to search for.
• Security & permissions-based access: Glean respects existing permission structures, ensuring that users only see information they're authorized to access. This feature is crucial for maintaining data governance and compliance within organizations.

Limitations of Glean enterprise search

• Lack of AI memory: While Glean excels at retrieving information, it doesn't retain long-term context or learn from past interactions in the same way that Tanka does. This limitation can affect the tool's ability to provide increasingly personalized assistance over time.
• Limited collaboration tools: Glean's primary focus is on search and information retrieval. Unlike Tanka, it lacks advanced team collaboration features and smart replies that can enhance day-to-day communication and productivity.
• Focus on large enterprises: Glean's solution is primarily tailored for large organizations with complex data ecosystems. This focus may make it less suitable for startups or small teams looking for a more intuitive, AI-powered knowledge assistant that can grow with their needs.
