Google Gemini vs Glean
A plain-English comparison to help you choose between them.
Both promise answers grounded in your work, and they mean different things by your work. Gemini means the Google surround: inside Gmail, Docs, Drive and Meet, holding very long documents in one session and grounding answers in live Search, with a genuinely capable free tier underneath. Glean means the whole estate regardless of vendor, indexing the organisation's applications and returning permission-aware cited answers across drives, wikis, tickets and chats. Pick Gemini when work really does live in Google and the integration advantage is free money; pick Glean when it is scattered across a dozen systems and finding things is the actual bottleneck.

Side by side
- Summary
Gemini is Google's AI assistant, with a genuinely capable free tier and paid plans that add deeper models, research and generation. It answers with images and files understood, drafts and analyses, generates imagery and video, and runs Deep Research for long, sourced investigations.
Its distinctive strength is the Google surround. Gemini works inside Gmail, Docs, Drive and Meet, holds very long documents in one session, and grounds answers in live Search. Gems let you shape reusable assistants for recurring jobs, and Gemini Live makes it conversational on the phone.
MoreLess
For anyone whose work already lives in Google's tools it is the shortest path to serious AI, and capability per pound is strong even outside them.

- Very long documents held and reasoned over in one session
- Deep Research reports with sources
- Image and video generation alongside everyday assistance
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- The consumer Gemini app treats data as consumer data; Workspace/Business Gemini keeps org data private and untrained. For a first-timer, avoid pasting confidential or personal financial data into the free consumer app.
- Summary
Glean is enterprise search that respects who you are: it indexes the organisation's applications and answers questions with citations, showing each person only what their permissions allow. The knowledge sprawl across drives, wikis, tickets and chats becomes one queryable surface.
Its Work AI direction builds on that foundation: assistants and agents grounded in company knowledge, with the permission-awareness that makes enterprise deployment survivable.
MoreLess
It is bought at organisational scale: the indexing, connectors and governance assume hundreds of seats and a real IT function.

- Assistants and agents on the same governed foundation

By area
Where each one pulls ahead, area by area.
| Area | Google Gemini | Glean |
|---|---|---|
| By job | ||
| Legal & compliance | Google Gemini compares provisions across documents in one session, which is reasoning over material you already hold rather than finding where it sits | Glean searches across systems without widening anyone's access, which is the condition a compliance function attaches before any search is allowed at all |
| Productivity & personal assistant | Google Gemini takes the automatic notes and summaries out of a Meet call, so the record of a conversation writes itself where the conversation happened | Glean identifies who has worked on something before you start, which is a question no amount of drafting capability answers |
| By task | ||
| Search & knowledge retrieval | Gemini's private-side retrieval inherits your Drive's tidiness, so a messy drive produces messy answers | Glean searches every connected system from one box, which is the shape of the problem when the answer exists somewhere and nobody can find it |
Common questions
If we are a Google shop, is Glean redundant?
Only if Google genuinely holds everything, which is rarer than it feels. Tickets, wikis, code hosts and chat tools usually sit outside Workspace, and that scatter is precisely what Glean indexes. The honest test is to list where last month's answers actually lived. If the list is one vendor, Gemini covers it; if it is six, that is the case Glean is priced for.
How do the two purchases differ in shape?
Almost completely. Gemini follows Workspace licensing, so capability and admin controls arrive with the plan rather than a project, and a capable free tier means anyone can start today. Glean assumes hundreds of seats, a real IT function and enterprise procurement, which makes it a programme with an owner rather than a subscription someone expenses.
Which is more useful outside the office?
Gemini, and it is not the point of Glean to compete there. Gemini generates imagery and video, runs Deep Research on the open web and is conversational on the phone, so it doubles as a general assistant. Glean is a search and grounding layer over company knowledge; asking it general questions is using an expensive index for something a free assistant does better.
