Glean AI Chrome Extension Review: A Deep Dive Into Its Features

Allen

TL;DR

Glean AI's Chrome extension acts as a powerful enterprise search assistant, unifying your company's scattered knowledge into a single, searchable interface. It connects with apps like Google Drive, Slack, and Jira to make information discovery fast and intuitive, aiming to significantly boost productivity. While its core search functionality is highly praised by users for saving time, its more advanced generative AI features are still evolving and can sometimes struggle with industry-specific terminology.

What Is Glean AI and How Does the Extension Work?

Glean AI is a modern work assistant designed to solve one of the biggest challenges in today's digital workplace: information overload. Described by users on G2 as a tool that brings all your company's knowledge together, it functions like a private Google for your organization. Instead of manually searching through dozens of different applications, the Glean AI Chrome extension allows you to find exactly what you need from one central point, whether it's a document, a Slack message, or a Jira ticket.

The core of Glean's power lies in its ability to index and understand the context of your company's information. It goes beyond simple keyword matching by using artificial intelligence, specifically a technique called Retrieval-Augmented Generation (RAG), to comprehend the relationships between documents, people, and conversations. As explained in a review by Slite, this allows Glean to deliver highly personalized and relevant results based on your role, your team's projects, and your recent activity, all while respecting existing data permissions.

Users primarily interact with Glean through its seamless browser integration. The Chrome extension can transform your new tab page into a productivity hub, offering a search bar, recent documents, and calendar events. It also provides a sidebar for quick searches without leaving your current page. This setup is designed to integrate directly into your existing workflow, reducing the time spent switching between applications and breaking down the knowledge silos that can slow teams down.

Glean connects with a vast array of workplace tools to create its unified knowledge graph. Some of the most common integrations include:

• Google Workspace (Drive, Gmail, Calendar)

• Microsoft 365

• Slack

• Jira

• Confluence

• Salesforce

Core Features: AI Search, Agents, and Knowledge Management

The Glean platform is built on a foundation of powerful features designed to turn scattered information into actionable knowledge. Its primary function is its AI-powered knowledge search, which allows users to ask questions in natural language and receive answers synthesized from across all connected company apps. This contextual search engine understands not just what you type, but what you mean, surfacing the most relevant documents, conversations, and data points to save you time.

Beyond search, Glean offers "Glean Agents," a system for automating multi-step business processes. As detailed by TextCortex, these agents can be built to handle repetitive workflows, analyze data, and execute tasks independently. For example, an agent could be designed to automatically compile weekly project updates by pulling data from Jira, Slack, and Google Docs. The platform also includes an AI App Builder, enabling teams to create custom Q&A chatbots for specific needs, such as a bot in Slack that can instantly answer HR policy questions.

Glean also provides tools for active knowledge management and curation. Features like "Collections" allow users to group related documents and links for specific projects, creating a shared repository for team resources. "Go Links" act as custom, memorable shortcuts for frequently accessed pages or tools, simplifying navigation. These features, highlighted in the Slite review, help transform Glean from a purely reactive search tool into a proactive knowledge hub where important information can be organized and easily shared.

While Glean excels at helping you find and analyze existing knowledge within your enterprise, the initial creation and structuring of that knowledge often happens in dedicated collaborative spaces. For teams looking to enhance their content creation process, a multimodal tool like AFFiNE AI can be a powerful complement. It acts as a copilot for turning raw ideas into polished documents, visuals, and presentations, featuring capabilities like inline AI editing and one-click mind map generation. This makes it an excellent solution for the brainstorming and content development that precedes knowledge archiving.

Pros and Cons: A Balanced View from Real Users

Based on extensive user feedback from platforms like G2 and Gartner, Glean is a highly-rated tool, but it's not without its limitations. The consensus is that its core search functionality is a game-changer for productivity, while its newer AI capabilities are still maturing.

User reviews consistently praise Glean for its ability to save a significant amount of time. One reviewer on G2 stated, "The ability to search across all our workplace tools...saves me tons of time." This sentiment is echoed across many reviews, with users highlighting the ease of use and the immediate productivity boost from having a single source for information discovery. The intuitive interface and seamless integration into daily workflows are frequently cited as major strengths.

However, some users point out areas for improvement. A common piece of feedback is that the generative AI features can be inconsistent. One user on Gartner noted that the "gen AI feature does not really work for most searches and seems like a gimmick, at least for now." Others on G2 have mentioned that the AI can sometimes "hallucinate" or provide incorrect answers, and it may struggle to understand highly specific industry jargon. Minor issues like slow loading times for older documents or search results being occasionally too broad are also mentioned.

ProsCons
• Time-Saving: Drastically reduces time spent searching for information across multiple apps.
• Ease of Use: Intuitive interface with minimal onboarding friction.
• Unified Knowledge: Effectively breaks down information silos by connecting disparate data sources.
• Seamless Collaboration: Enhances team efficiency by making shared resources easily discoverable.
• Inconsistent AI: Generative AI features can sometimes be inaccurate or "hallucinate."
• Jargon Difficulty: May struggle with highly specific or technical industry terminology.
• Broad Results: Search can occasionally return results that are too broad, requiring extra filtering.
• Minor Performance Issues: Some users report slow loading times or occasional bugs.

Glean AI Pricing and Enterprise Suitability

A common question for prospective users is about the cost of Glean AI, but the company does not offer public pricing tiers. Instead, Glean operates on a custom quote model tailored to the specific needs of each organization. This approach is typical for enterprise-grade software where usage, complexity, and scale can vary dramatically from one company to another.

According to an analysis by TextCortex, the final price is influenced by several key factors. These include the size of the organization (number of employees or "seats"), the number and type of integrations required, the level of customization needed, and the selected support tier. While no official numbers are published, market analysis suggests that pricing can start at around $50 per seat per month, making it a significant investment geared towards businesses rather than individuals or very small teams.

The pricing structure and feature set clearly position Glean as a solution for mid-market and large enterprise companies. These are the organizations that typically suffer the most from knowledge silos, with information scattered across dozens of applications and thousands of employees. The user demographics on review sites like G2 confirm this, with the majority of reviewers coming from companies with over 50 employees, and a large portion from enterprises with over 1000 employees. For these businesses, the return on investment comes from reclaiming the hours employees would otherwise waste searching for information, leading to substantial productivity gains across the organization.
