# Glean

Glean is an enterprise AI search and assistant platform that helps organizations find information across their internal applications and automate workflows using large language models.

Glean is an enterprise software company that provides an AI-powered workplace search and assistant platform. The service indexes an organization's internal applications and data sources, allowing employees to search across them using natural language queries. Glean's platform is built on large language models and aims to provide accurate, personalized answers grounded in a company's internal knowledge base.

The company was founded in 2019 by former Google engineers who sought to apply search and artificial intelligence techniques to the enterprise context. Glean positions itself as a solution for the challenges of fragmented information across modern workplaces, where data resides in numerous SaaS applications, internal wikis, and code repositories. The platform integrates with a wide range of tools, including slack, google-workspace, microsoft-365, and jira, to create a unified search index.

## Core Technology

Glean's technology combines traditional enterprise search with modern [large-language-model](https://www.wikiprompt.org/wiki/large-language-model) capabilities. The platform uses [machine-learning](https://www.wikiprompt.org/wiki/machine-learning) to understand the relationships between people, content, and context within an organization. It employs a graph-based approach, mapping connections between documents, conversations, and users to improve the relevance of search results. The system also leverages [generative-ai](https://www.wikiprompt.org/wiki/generative-ai) to synthesize answers from multiple sources, providing users with a single, coherent response rather than a list of links.

A key feature is its ability to respect and enforce existing access controls. Glean indexes content but ensures that search results and AI-generated answers only include information that the requesting user is authorized to see. This is achieved through a security model that mirrors the permissions of the underlying source systems.

## Products and Features

Glean offers two primary products: Glean Search and Glean Assistant. Glean Search provides a unified search interface across all connected applications, with features such as natural language queries, personalized results, and proactive recommendations. Glean Assistant is an AI-powered conversational interface that can answer questions, summarize documents, and complete tasks such as drafting emails or creating reports.

The platform also includes developer tools and APIs that allow organizations to build custom integrations and embed Glean's capabilities into their own applications. Glean supports a wide range of connectors, including popular enterprise software like salesforce, servicenow, and github.

The company is exploring ways to improve the accuracy and reliability of its AI-generated answers, including techniques for [retrieval-augmented-generation](https://www.wikiprompt.org/wiki/retrieval-augmented-generation) and [fine-tuning](https://www.wikiprompt.org/wiki/fine-tuning) on enterprise-specific data. Glean also plans to expand its platform to support more use cases, such as automated workflow execution and deeper integration with enterprise-resource-planning systems.

The company's long-term vision is to become the primary interface for all workplace information, enabling employees to access knowledge and complete tasks through a single, intelligent assistant.
