Claude vs Gemini for Work

Claude and Gemini cover the same ground at work: a chat assistant on the web, desktop and phone, a way to keep context for a piece of work, connections to your other apps, an agent for longer jobs and a coding agent. The differences that decide it are elsewhere. Gemini is built into Google Workspace, so in Gmail, Docs, Sheets and Meet it is already on the screen. Claude sits outside both office suites and reaches into them through connectors: Google Workspace on every plan, and Microsoft 365 with a work account. Claude also lets any plan add its own tools over MCP, while Gemini’s equivalent is limited, for now, to personal accounts in the US. And each treats your data differently on personal and business accounts. Everything below follows Anthropic’s and Google’s own pages as of September 30, 2026.

Two narrower comparisons have their own pages: reusable setups in Claude Projects vs Gemini Gems, and the terminal agents in Gemini CLI vs Claude Code vs Codex CLI. This page is the general comparison for work.

Claude vs Gemini at a glance

• Maker: Claude is made by Anthropic; Gemini by Google.
• Apps: both on the web, in desktop apps for Mac and Windows, and in iPhone and Android apps. Gemini is also built into Gmail, Docs, Sheets, Slides, Drive, Chat and Meet.
• Plans, by name: Claude has Free, Pro, Max, Team and Enterprise. Gemini comes with no plan, with Google AI Plus, Pro or Ultra on a personal account, or with a Google Workspace edition at work.
• Keeping context: Claude uses projects and skills. Gemini uses notebooks, and Gems, which are turning into skills.
• Other apps: Claude has connectors, including custom ones to any remote MCP server. Gemini has Connected Apps, and custom apps over MCP on eligible personal accounts.
• Longer jobs: Claude Cowork, now merging into ordinary Claude chats. Gemini Spark, an experimental agent on Google AI Pro and Ultra.
• Coding: Claude Code; Gemini CLI, Gemini Code Assist and Antigravity.

The apps

The chat apps look alike and do the everyday work alike: draft, summarize, analyze a file, search the web. The difference is where you open them. Gemini is a side panel in the Google apps you already have open, so a reply to a Gmail thread or a formula in Sheets starts from the document itself. Claude is a separate app you bring documents to, or that fetches them through a connector. Around the chat, Claude adds artifacts, documents and small tools you can share, and Cowork for jobs that end in a finished file; Anthropic is folding Cowork into ordinary chats, as what is Claude Cowork explains. Gemini adds Gemini Spark, an agent that runs multi-step and scheduled tasks across your connected apps, which Google labels experimental and limits for now to personal accounts on Google AI Pro or Ultra.

Projects, notebooks, Gems and skills

Both let you stop repeating yourself, in two shapes. For one body of ongoing work, Claude has projects and Gemini has notebooks, which sync with Gemini Notebook, formerly NotebookLM. For a behavior you reuse across unrelated tasks, Claude has skills and Gemini has Gems, which Google is turning into skills from November 2026 on personal accounts and during 2027 on Workspace accounts. The feature-by-feature comparison is in Claude Projects vs Gemini Gems, and the Gem changeover in Gemini Gems. One point matters for teams: skills in the Gemini app are not yet available on work or school accounts, so a Workspace team keeps using Gems until its switch date.

Connectors, connected apps and MCP

Both reach other services, and both use the Model Context Protocol to do it, but they open it to different people. Claude’s custom connectors take the address of any remote MCP server on every plan, with Free accounts limited to one and Team and Enterprise owners adding them for their organization. How that works is in Claude connectors explained.

Gemini starts from a fixed list. Google’s Connected Apps availability table↗ (opens in a new tab) lists Google’s own apps and partners such as GitHub, Dropbox, Linear, Monday.com, Airtable and Canva, and which account types each one supports. On a work account, the list is mostly Google Workspace itself: Gmail, Calendar, Chat, Docs, Drive, Keep and Tasks.

To add a tool of your own, Google’s page on custom apps in Gemini↗ (opens in a new tab) takes an MCP server URL, but only for people 18 or over in the US, signed in with a personal account, in English, with Keep Activity on, in the web or mobile app. It says Gemini asks for confirmation before any write action, and that Google does not control or secure third-party MCP servers. Inside Workspace apps, Gemini connects to partners Google chose, such as Asana, Salesforce and Monday, as Gemini for project management describes.

Google Workspace or Microsoft 365?

If your company runs on Google Workspace, Gemini is the shorter path: it is included in the business and enterprise editions, it works inside each app, and Take notes for me writes Meet notes into a Doc. Claude reaches the same files from outside. Anthropic’s page on Google Workspace connectors↗ (opens in a new tab) says Gmail, Google Calendar and Google Drive connect on every plan, asks for your approval by default before sending mail or sharing and moving files, and adds a beta pane where you and Claude edit the same Doc, Sheet or Slides file at once. On Team and Enterprise, an owner turns the connectors on first.

If your company runs on Microsoft 365, the picture reverses. Anthropic’s Microsoft 365 connector↗ (opens in a new tab) reaches SharePoint, OneDrive, Outlook and Teams on every Claude plan with a work or school Microsoft account, read-only by default, with sending mail, writing files and posting in Teams only when an administrator allows it. Gemini’s Connected Apps list has no Outlook, Teams, SharePoint or OneDrive entry. For a mixed company, Claude is the one assistant that reaches both suites; the setup is in Claude with Microsoft 365.

Data controls

• Claude, personal plans: Anthropic’s privacy center says it uses your chats and coding sessions to improve its models only if you choose to allow it↗ (opens in a new tab), and incognito chats are never used.
• Claude, Team, Enterprise and the API: not used for training by default.
• Gemini, personal accounts: the Gemini Apps Privacy Hub↗ (opens in a new tab) says that with Keep Activity off, and no feedback sent, future chats are not used to improve Google’s AI models and are kept for 72 hours. With it on, a subset of chats is read by human reviewers after being disconnected from your account.
• Gemini, Workspace accounts: Google’s Workspace pages say submissions are not used to train models and are not reviewed by humans.

One trade-off to know on the Gemini side: several newer features, including skills, Spark and custom apps, require Keep Activity on. On a personal account you choose between those features and the stricter data setting.

Coding CLIs, briefly

Both send serious coding to an agent in the terminal. Claude Code signs in with a paid Claude plan or a cloud provider account and reads CLAUDE.md. Gemini CLI is open source and reads GEMINI.md, but since June 18, 2026 it no longer accepts a personal Google sign-in; it needs a Gemini API key, Vertex AI or a Gemini Code Assist Standard or Enterprise license, and Google points individual developers to Antigravity. The full matrix is in Gemini CLI vs Claude Code vs Codex CLI, and the licensing change in Gemini CLI vs Gemini Code Assist.

Claude or Gemini? Pick by job

• Replying to mail, fixing a Doc or taking Meet notes inside Google Workspace: Gemini, which is already in the app.
• Working across Outlook, Teams and SharePoint: Claude with the Microsoft 365 connector.
• A company with some teams on each suite: Claude, which reaches both.
• Connecting your own tool on a work account: Claude, through a custom connector an owner adds. On Google’s side that takes Gemini Enterprise, a separate Google Cloud product, not Gemini in Workspace.
• Answers only from a fixed set of sources, with Audio Overviews: Gemini Notebook.
• One body of work returned to over weeks: a Claude project or a Gemini notebook.
• A task that ends in a file, such as a board-meeting deck: Claude Cowork, or Gemini Spark on an eligible personal plan. Try both on the same task.
• Changes to a codebase: Claude Code, or Gemini CLI with an API key or a company license.

Using both on one board

Plenty of teams end up with both: Gemini because it is in their Google apps, Claude for long documents or code. Then the list of work should sit outside either one. fenbs is a task board both can reach over MCP: Claude as a custom connector, and Gemini through Gemini CLI or the Gemini app’s custom apps where your account qualifies. Each signs in through the browser and acts under your role on the board. Tasks are features, enhancements or bugs with a note, a plan and a priority from 1 to 10, moving through To Do, Next Up, In Progress and Completed, and History records which assistant changed what. Standing rules go once on the Decisions and rules page, which every connected assistant reads first, instead of into a Claude project and a Gem separately. fenbs has no due dates, sprints or assignee field, and Gemini in Workspace cannot connect to it.
