# ChatGPT vs Gemini for work: which should you use? > ChatGPT vs Gemini for office work: October 2026 prices, Gmail and Google Docs fit, data and training settings, and which assistant to pick for your team. Source: https://learn.ynteractive.com/content/compare/chatgpt-vs-gemini · Updated 2026-10-08 · Free from Stepthrough (https://learn.ynteractive.com) Quick answer If your team works in Gmail, Google Docs and Google Sheets, start with **Gemini**: it works inside those apps on Google Workspace plans, so it can summarize the thread or document you already have open. If you don't use Google Workspace, or want one assistant for everything in its own window, start with **ChatGPT**. Both have free plans, and their main individual plans cost about the same: $20 a month for ChatGPT Plus and $19.99 for Google AI Pro, as of October 2026. Last updated October 8, 2026 By [Robert Breen](https://learn.ynteractive.com/content/about) · Published October 8, 2026 · Prices and features checked as of October 2026 This comparison is for office workers and owners of small and mid-size businesses. You can practice the same job in both: the free [Gemini in Gmail lesson](https://learn.ynteractive.com/content/gemini-in-gmail-summarize-and-reply) summarizes a thread and drafts the reply inside Gmail, and [Reply Faster: Customer Emails](https://learn.ynteractive.com/content/chatgpt-reply-to-customer-emails) does it in ChatGPT. ## How do they compare at a glance? **ChatGPT and Gemini at a glance (as listed by OpenAI and Google, as of October 2026)** | | ChatGPT | Gemini | | --- | --- | --- | | Made by | [OpenAI](https://learn.ynteractive.com/content/glossary/openai) | Google, with models from [Google DeepMind](https://learn.ynteractive.com/content/glossary/google-deepmind) | | Free plan | Yes, Free | Yes, the Gemini app is $0 with a Google account | | Paid plan for one person | Go $8 a month (may include ads); Plus $20 a month; Pro from $100 a month | Google AI Plus (check price); Google AI Pro $19.99 a month; Google AI Ultra from $99.99 a month | | Team plan | Business: $25 per user a month, or $20 billed annually | Google Workspace: Business Starter $7, Standard $14, Plus $22 per user a month (flexible plan prices) | | Works inside | Its own app, with connectors to Google Drive, Microsoft 365 and others | Gmail, Docs, Sheets, Meet and the Gemini app on Workspace plans | | Main models, as of October 2026 | GPT-6 on paid plans; GPT-5.6 on Free and Go | Gemini 3.1 Pro, plus faster Flash models; Deep Think on Ultra | | Trains on personal chats? | Yes unless you turn off "Improve the model for everyone" | Yes unless you turn off "Keep Activity" | | Trains on business plans? | No, by default | No, without permission, per Google's Workspace privacy hub | | Saved workspaces | Projects | Gems and Gemini Notebook | Prices and features as listed on each vendor's own pages, as of October 2026.

If your email is Gmail on a Workspace plan, Gemini wins on convenience. In the [Gemini in Gmail lesson](https://learn.ynteractive.com/content/gemini-in-gmail-summarize-and-reply), you click **Summarize this email** on a six-message thread, ask **Ask Gemini** what you still owe and by when, then write the reply with **Help me write** and **Polish** without leaving Gmail. Google lists Gemini in Gmail on every Workspace business plan, including Business Starter at $7 per user a month. ChatGPT writes equally good emails, but you paste the thread in and copy the reply out. That is not a big cost for a few emails a day, and it works with any email system, including Outlook. The [Reply Faster lesson](https://learn.ynteractive.com/content/chatgpt-reply-to-customer-emails) shows the routine. ## Which is better for documents and spreadsheets? Gemini works inside Google Docs and Sheets on Workspace Business Standard and above, and Google lists a 1 million token context window on Google AI Pro and Ultra for the Gemini app. Gemini Notebook answers questions from only the documents you load, with citations, which the free [Gemini Notebook lesson](https://learn.ynteractive.com/content/notebooklm-gemini-notebook-cited-answers-briefing-doc) covers. ChatGPT handles uploaded Word, PDF and Excel files well and can turn data into tables and charts. OpenAI also lists Excel, Word, PowerPoint and Google Sheets extensions on its pricing page. For files that live in Google Drive, Gemini is the shorter path; for a mix of file types and systems, ChatGPT is the more flexible one. ## How much do ChatGPT and Gemini cost? For one person, ChatGPT Plus is $20 a month and Google AI Pro is $19.99 a month, as of October 2026. Google AI Pro also includes 5 TB of storage and Gemini in Gmail and Docs on a personal Google account. ChatGPT has a cheaper Go plan at $8 a month; Google has Google AI Plus, whose price varies by country. For a business, the comparison is different. ChatGPT Business is an extra $25 per user a month, or $20 billed annually. Gemini comes inside Google Workspace, which you may already pay for as your email system: Business Starter at $7, Standard at $14 and Plus at $22 per user a month on flexible plans, with lower annual and promotional prices on Google's page. ## Which handles my data better? On business plans, both say they don't train on your content by default: OpenAI for ChatGPT Business, Enterprise and the API, and Google for Gemini in Workspace. On personal accounts, both can. In ChatGPT, turn off **Improve the model for everyone** under **Data controls**. In Gemini, Google's privacy hub says personal activity can be used to improve its models, including with some human review, unless you turn off **Keep Activity**; with it off, Google says chats are kept for 72 hours. For client work, use the business account your company manages. The [AI acceptable use policy](https://learn.ynteractive.com/content/glossary/ai-acceptable-use-policy) entry explains what a good policy covers. ## Should my team use both? Many Google Workspace teams use Gemini inside Gmail and Docs for everyday drafting and keep ChatGPT for longer, standalone jobs such as research reports or images. That works, as long as the same data rules apply in both. If you can only fund one, the tool built into your email usually gets used more.

For everyday office work, yes. Both write, summarize and analyze well. The bigger difference is where they work: Gemini inside Google's apps, ChatGPT in its own app with connectors. ### Is Gemini free? Yes. The Gemini app is free with a Google account, and Google Workspace business plans list Gemini in Gmail. Google AI Pro is $19.99 a month for higher limits, as of October 2026. ### Can Gemini read my Gmail? On a Workspace account or a Google AI plan, Gemini can work with the email you have open and answer questions about your inbox. On a Workspace account, Google says it doesn't use that content to train models without permission. ### Do ChatGPT prompts work in Gemini? Yes. A prompt with a role, context, task and format works the same way in both, which is why the skills from the ChatGPT lessons carry straight over. ## Where do these prices and features come from?
