ChatGPT vs Gemini (2026)

Quick verdict: which one fits you

Price at a glance: personal plans

Google's paid plans are also storage plans, shared with up to five family members7. ChatGPT Plus has no annual option6. Prices are US prices as shown on 19 Oct 2026; tax may be added.

Price at a glance: business plans

This isn't quite apples to apples. A Google Workspace seat is your business email, storage, video calls and documents, with Gemini included. A ChatGPT Business seat is the AI only, so you keep whatever email you already use.

Annual Workspace plans lock in your seat count until renewal; flexible plans let you add and remove people any month2. ChatGPT Business lets you buy workspace credits for usage past the included limits, and API usage is billed separately3. Enterprise pricing for both is through sales.

What each can actually do as an agent

Both have moved past "chatbot". Here's what each one can do for you today, from their own help pages. One housekeeping note: ChatGPT's old "agent mode" is gone. OpenAI now points you to ChatGPT Work for multi-step tasks18, and dots for always-on work9.

Where ChatGPT pulls ahead

Finished work. ChatGPT Work goes from a goal to a document, spreadsheet, deck or website4, and on the desktop app it can use your local files and apps with your permission4. It's also the better fit for Microsoft shops: Outlook, Word, Excel and PowerPoint all work with it4. And dots, the always-on agents, are available to businesses on Premium seats today9.

Where Gemini pulls ahead

It's already inside Gmail, Docs and Drive, so there's nothing to connect for a Google company1. Gemini in Gmail can clean up your inbox in bulk, with a confirm step and 60 seconds to undo14. Google's plans also bundle storage, and Pro adds YouTube Premium Lite and Google Home Premium7. The catch for Google's most agentic features: many are limited by country. Chrome auto browse is US and India only, and Gemini Agent is US and English only7.

Privacy: is it training on your chats?

Personal plans

• ChatGPT: OpenAI may use your conversations to improve its models, and you can opt out any time6. Turn off "Improve the model for everyone" in Settings → Data controls. Temporary chats aren't used for training and may be kept up to 30 days for safety19.
• Gemini: with Keep Activity on, Google uses your activity to improve its services, including training its AI, and human reviewers read some chats. Reviewed chats are kept up to 3 years, even if you delete your activity16. Activity auto-deletes after 18 months by default16.
• The Gemini trade-off: turning Keep Activity off stops training on future chats, but Google Workspace stops working as a connected app until you turn it back on16. To use Gemini with your Gmail and Calendar, Keep Activity has to be on17.
• Ads: ChatGPT Free and Go may show ads84. Google says Gemini chats aren't used to show you ads16.

Business plans

• ChatGPT Business: OpenAI won't train on your workspace's data3, including data from connected apps, by default20. Admins can view, export and delete members' conversations and set how long data is kept20.
• Gemini with Workspace: your content isn't reviewed by humans or used to train AI models outside your domain without permission21. Licensed users' Gemini app chats aren't used for training and are never reviewed by humans22. Admins set Gemini app retention up to 36 months21.

One habit for both: connect only the apps a task needs, and don't hand over passwords in the chat. OpenAI gives exactly this advice18, and Google warns that Gemini can make mistakes like buying things or sharing your data unexpectedly, so watch its browsing16.

Security and admin for business tiers

• Certifications: ChatGPT Business has completed a SOC 2 Type 2 audit20. Google lists SOC 1/2/3, ISO 9001, ISO/IEC 27001, 27701, 27017, 27018 and 42001 for Gemini, plus FedRAMP High authorization21. OpenAI's ISO certifications for Business weren't stated on the pages we checked: unknown.
• Sign-in and admin: ChatGPT Business has SSO and multi-factor authentication12, with SAML SSO for enterprise-level sign-in20. SCIM, role-based access and data residency need Enterprise12. On supported Workspace editions, admins can turn Gemini features on or off per app, and Gemini audit logs are available21.
• Data protection: on supported Workspace editions, existing data loss prevention rules apply to Gemini output, and file restrictions can keep Gemini away from sensitive documents21. Gemini can't act on email and files encrypted with your own keys22.
• Healthcare: Gemini with Workspace can support HIPAA workloads22. For OpenAI, a BAA needs a contracted plan, not self-serve Business3.
• Prompt injection: Gemini checks content for threats before acting and blocks or excludes it21. ChatGPT offers Lockdown Mode, which limits web access to reduce data leaks from prompt injection, and admins can set it for members4.
