Glean, a leader in Work AI, has unveiled the third-generation Glean Assistant—an AI extension of employees at work—now capable of deeply personalizing results and actions uniquely for every employee, and accomplishing complex agentic tasks without advanced prompt engineering. The company also announced significant expansions to its Work AI platform, introducing new SDKs and MCP capabilities that provide enterprises with openness, interoperability, and context to build, extend, and operationalize powerful AI agents at scale. Underpinned by Glean’s new Enterprise Graph, these innovations advance organizations toward the superintelligent enterprise, where AI embeds into every workflow for faster, more accurate, and autonomous work.

Enterprise Graph: Core Context for Work AI

Glean’s vision is to enable AI that truly understands the enterprise—its data, people, and processes. At the core is Glean’s expanded Enterprise Graph, the intelligence layer that builds a dynamic understanding of how work happens across the enterprise. The Enterprise Graph captures relationships between people, content, workflows, and applications—combining Glean’s existing knowledge graph, which understands company-wide systems and information, with a personal graph for each employee that reflects their projects, collaborators, and work style. Together, this forms a living map of enterprise context. Though invisible to users, the Enterprise Graph powers every experience in Glean—from personalization to agentic execution—and makes Glean’s AI truly enterprise-ready, delivering the context, structure, and nuance needed to achieve meaningful outcomes with AI.

Glean Assistant: Personalized and Agentic Intelligence

Most AI assistants are generic, disconnected from enterprise context, and lack knowledge of users or ongoing work beyond a chat session. As a result, they answer questions and summarize information but rarely provide true guidance, often forcing employees to upload documents, master prompt engineering, and describe desired tone. Glean Assistant now delivers advanced personalization, contextual awareness, and true agentic intelligence—uniquely for every employee. It doesn’t just respond—it understands goals, creates plans, and carries out complex, multi-step work, adapting as it goes. Without requiring advanced prompt engineering, Glean Assistant acts as an intuitive partner that can think, decide, and execute, delivering complete outcomes tailored to each employee’s way of working.

Personal features include a personal graph that knows each user’s tasks, projects, collaborators, and work style for natural experiences. Writing reflects context and voice, learning tone for emails, documents, or messages from past work across 100+ connected applications to generate natural, authentic content. Canvas, a new interactive workspace, enables inline editing while guiding stronger writing skills, turning creation into dialogue for faster, polished output with improved clarity and equity. Employees control experiences with choices for faster responses or extended thinking, and LLM family selection based on preferences.

Agentic Capabilities and Platform Expansions

Agentic features leverage the second-generation Agentic Engine for performance gains in writing, data analysis, and tool use, using the Enterprise Graph for adaptive planning and cross-system execution. Glean Assistant reasons through multi-step challenges, gathers information, refines approaches, orchestrates sub-agents for parallel work, and deploys scouts for new insights. It handles tasks without multi-paragraph prompts, simply describing outcomes for results. When context is missing, it asks clarifying questions and adapts plans. It determines needed knowledge across company and web sources, including image content, consolidating into single responses.

For broader challenges, Glean enhances platform capabilities for powerful agents with richer actions, MCP directory and host support, and intuitive building. The upgraded builder enables vibe coding via chat for non-developers. It supports 100+ new native actions in apps like Slack, Microsoft, Salesforce, GitHub, and Google, plus MCP for larger operational surface. A curated directory of 20+ validated MCP servers simplifies configuration, and enterprises can add custom hosts for data, actions, and agent collaboration. Openness allows model, framework, and tool choices with enforced permissions, security, and governance. APIs and SDKs expose personalization and reasoning for embedding agentic intelligence into apps and workflows.

“The future of work is the superintelligent enterprise, where AI understands people and organizations deeply enough to transform how work gets done. At Glean, we’ve built the Enterprise Graph to make that future real, giving Glean Assistant the context to act as a true teammate. With today’s announcements, Glean is setting a new standard for AI at work - assistants that are deeply personal and adapt to every employee, and powerful, interoperable agents that drive work forward with trust and reliability.” - Arvind Jain, Founder & CEO, Glean

“Enterprise adoption of agentic AI is becoming a strategic pillar for CIOs seeking to modernize workflows and rethink productivity at scale. What distinguishes Glean’s latest assistant and platform evolution is not just the technical sophistication, but the emphasis on personalization, interoperability, and outcome-driven orchestration. This signals a shift from isolated use cases to scalable agentic intelligence embedded directly into enterprise systems, a core tenet of where enterprise AI is heading.” - Nick Patience, VP & Practice Lead, AI Platforms, Futurum

Availability includes today’s features like Enterprise Graph, Agentic Engine 2 in Assistant, schedule agents, and enhanced Chat API; beta for personalized writing and conversational builder; coming soon for Canvas and 100+ actions.

These advancements position Glean as a foundational platform for embedding AI into enterprise workflows, fostering innovation, efficiency, and the superintelligent enterprise vision through contextual, scalable intelligence.
