## What people mean by a company brain

[Savant describes itself as an operational memory layer that turns scattered company knowledge into searchable operating context for people and AI.](https://heysavant.com/)

[Savant says it consolidates documented information and captures operational context that is not written down, including procedures, decisions, dependencies, and edge cases.](https://heysavant.com/) [It presents its offering as a context layer between company data and reliable automation.](https://heysavant.com/)

## Enterprise search across company tools

[Glean describes its platform as enterprise AI that understands a company, and describes enterprise search as a way to find answers across the company.](https://www.glean.com/) [It says context is integrated across enterprise tools and users see only information they are allowed to see.](https://www.glean.com/)

[Notion describes Enterprise Search as finding answers across connected apps, including Slack, Google Drive, and GitHub.](https://www.notion.com/product/ai) [It also describes Notion AI as a built-in teammate inside Notion, using workspace and connected-app context when enabled.](https://www.notion.com/product/ai)

## Governed knowledge for people and AI

[Guru describes itself as a governed knowledge layer for enterprise AI.](https://www.getguru.com/) [It says it structures, governs, and continuously improves company knowledge so AI tools and people can get answers they can trust.](https://www.getguru.com/)

[Guru lists permission-aware AI, full audit trails, citations on every answer, and enterprise SSO among its capabilities.](https://www.getguru.com/) These describe Guru's product.

## Knowledge base and enterprise search are not identical

The named products use these terms in different ways. [Savant explicitly distinguishes its offering from enterprise search, doc chatbots, wikis, and knowledge bases.](https://heysavant.com/)

[Glean and Notion describe finding answers across company or connected tools](https://www.glean.com/) [while Guru emphasizes governing and improving company knowledge](https://www.getguru.com/). These descriptions show how the products position themselves.

## A personal knowledge base with MCP

KnowMan saves articles and links, reads and tags them, answers questions with citations, and keeps saved claims, decisions, and playbooks. Its MCP server provides tools to search [saved items](https://www.knowman.io/guides/how-to-save-articles), ask questions, read an item, save a URL, see [recent items](https://www.knowman.io/guides/personal-knowledge-base), and access saved memories. [KnowMan AI knowledge base](https://www.knowman.io/guides/ai-knowledge-base) [KnowMan MCP server guide](https://www.knowman.io/guides/mcp-server-knowledge-base)

The MCP server runs locally over stdio or as a hosted remote server at https://api.knowman.io/mcp using Streamable HTTP. The hosted server supports OAuth sign-in or an API key. [KnowMan MCP server guide](https://www.knowman.io/guides/mcp-server-knowledge-base)

## Where KnowMan fits

KnowMan is built for one person's library today. It gives that person a way to save and ask questions about articles and links, then make that knowledge available to [AI clients](https://www.knowman.io/guides/connect-any-ai-to-your-notes) through MCP.
