Glean Alternatives in 2026: 8 Options Compared for Engineering and Product Teams

Disclosure: Memora publishes this article and Memora is one of the products compared. We have tried to describe every product, including our own, from its public documentation. Pricing and features change often; check the linked vendor pages before you decide.

What Glean does well, and why teams still compare alternatives

It's worth being accurate about Glean before looking at alternatives. According to its own documentation, Glean offers 275+ connectors (including Slack, GitHub, GitLab, Jira, Confluence, Google Drive and Notion), enforces the permissions of each source system, and provides both an MCP server and the ability to connect to remote MCP servers. It can run as Glean-hosted SaaS or in the customer's own GCP or AWS account. If you need broad coverage across a large company, that is a strong package.

The reasons teams compare alternatives are usually more practical:

• Pricing isn't published. Glean's pricing page asks you to book a demo. That's normal for enterprise software, but it makes early budgeting and small-team trials harder.
• You may already own something close. Microsoft 365 Copilot and Atlassian Rovo now include cross-tool search and connectors, and Rovo is included in paid Atlassian Cloud plans.
• Your questions are about engineering work. If most questions sound like "why does checkout retry payments three times?", what matters is how well a tool connects pull requests, tickets, threads and decisions, not how many connectors it has.

Comparison at a glance

Facts below come from each vendor's public pages, accessed 10 October 2026. "Not published" means the vendor asks you to contact sales.

The alternatives in detail

Microsoft 365 Copilot

What it is: Microsoft's AI assistant across Microsoft 365, which can search organizational content through Copilot connectors (formerly Microsoft Graph connectors). Microsoft-built connectors include GitHub, GitLab issues, Jira and Confluence.

Choose it if your company already runs on Microsoft 365 and most knowledge sits in SharePoint, Teams, Outlook and OneDrive. You avoid adding a vendor, and permissions follow your existing Microsoft identity setup.

Think twice if most of your knowledge lives outside Microsoft. Connectors need to be configured and maintained, and the $30 per user per month enterprise price adds up across a whole company.

Atlassian Rovo

What it is: Atlassian's AI search, chat and agents, built on its Teamwork Graph. Rovo is included in Atlassian Cloud Standard, Premium and Enterprise plans with monthly credit allowances, and it connects to Slack, GitHub and Google Drive with permission-aware connectors.

Choose it if Jira and Confluence are the center of your team's work. For many Atlassian customers it is the lowest-friction option because there's nothing new to buy.

Think twice if important context lives mostly in tools Atlassian doesn't connect well, or heavy usage would push you past the included credits.

Notion AI

What it is: Notion's built-in AI, now bundled into the Business plan ($20 per member per month) together with Enterprise Search, which reaches into Slack, Google Drive, GitHub and Jira (Jira is in beta). Results respect each connected app's permissions.

Choose it if Notion is already your team's main workspace. The jump from Plus to Business may cost less than a separate tool.

Think twice if your docs aren't in Notion, or you need connectors Notion doesn't list (we found no Confluence or GitLab connector).

Guru

What it is: A knowledge platform built around verified "cards" with assigned verifiers, plus AI agents that give cited, permission-aware answers. Guru lists connectors for Slack, GitHub, GitLab, Jira, Confluence, Google Drive and Notion, and offers an MCP server.

Choose it if you need curated, explicitly verified answers, such as support macros, HR policy or sales enablement, where someone must sign off on what's true.

Think twice if your team won't maintain verification. The model works best when ownership is clear. Pricing is now custom and not published.

Coveo

What it is: An AI search and relevance platform used heavily for customer service, websites and commerce, with a workplace offering. It supports Slack (Enterprise plan), Jira, Confluence and Google Drive, can replicate source permissions, and announced a hosted MCP server in February 2026.

Choose it if your main goal is customer-facing search or support deflection and you have the resources for a configured implementation.

Think twice if you mainly want an internal assistant for engineers. We couldn't confirm native GitHub or GitLab connectors (Coveo's connector directory was unavailable when we checked).

Sourcegraph

What it is: Enterprise code search and code understanding, with an MCP server on Enterprise plans. Pricing starts at a $16K minimum annual contract. Note the 2025 changes: Cody Free and Pro were discontinued in July 2025, and Amp became a separate company in December 2025.

Choose it if your hardest questions are about the code itself: where a symbol is used, what breaks if you change it, how a pattern spreads across hundreds of repositories. It also offers self-hosting.

Think twice if you need answers that combine code with Slack discussions, tickets or meeting notes. Sourcegraph focuses on code hosts.

Elastic

What it is: A search platform rather than a finished product. Elastic Enterprise Search (App Search and Workplace Search) is not available in version 9.0 and later. Its replacement is Elasticsearch with self-managed connectors (GitHub, Google Drive, Notion, Jira and Confluence Cloud are GA; Slack is in preview) and Agent Builder, which includes an MCP server.

Choose it if you have a platform team that wants full control, including self-managed deployment, and is willing to build and maintain the experience.

Think twice if you want something your team can use next week. You'll be running connectors, relevance tuning and the interface yourself.

Memora

What it is: Memora connects Slack, GitHub, GitLab, Jira, Linear, Confluence, Notion, Google Drive, Gmail, Microsoft Teams, Zendesk, Figma and Zoho, plus meeting transcripts from Google Meet, Zoom and Teams. It links related conversations, pull requests, tickets and documents, and answers questions in plain language with a link to every source. Answers only draw on content the person asking can already access. Memora also offers AI pull-request reviews and an MCP server for Claude Code and Cursor.

Choose it if you're an engineering or product team whose recurring question is "why was this decided?", and you want to try it without a sales process. There's a free plan, and paid plans are published on our pricing page.

Think twice if you need search across a whole enterprise with hundreds of systems, self-hosting, or third-party compliance certifications. Memora does not hold SOC 2 or ISO 27001 certification today. Our security page explains how data is handled, and we share documentation and a DPA on request.

Which alternative fits your situation?

• You're on Microsoft 365 and want one vendor: start with Microsoft 365 Copilot.
• You live in Jira and Confluence: try Atlassian Rovo first. You may already have it.
• Your team works in Notion: compare Notion's Business plan before buying something separate.
• You need human-verified answers for support or HR: look at Guru.
• Customer-facing search is the priority: evaluate Coveo.
• Code search across many repositories is the priority, or you need self-hosting: Sourcegraph.
• You want to build your own: Elastic.
• You need broad, permission-aware search across a large company and have the budget: Glean remains a strong option.
• You're an engineering or product team that wants decisions linked to their code, tickets and discussions: try Memora.

How to run a fair evaluation

1. Write down 15–20 real questions your team asked in the last month, including a few that need information from two or more tools.
2. Connect the same sources to each tool you trial, with the same user permissions.
3. Check every answer against its sources. Look at whether the citation actually supports the claim, not just whether a citation is present.
4. Test permissions deliberately: ask, as a restricted user, about a document that user shouldn't see.
5. Price it for your real team size, including add-on licenses, credit limits and the time someone will spend administering connectors.
