ChatGPT vs Gemini
Two catalogue entries side by side. Not a benchmark: we have not tested these products against each other.
Catalogue checked September 23, 2026.
ChatGPT
Plan price reference: Plus $20/month; API usage is billed separately
- Can produce confident but wrong answers
- Available models and limits depend on the plan
Gemini
- Plan names, prices and limits vary by region
- Consumer-plan coverage of programmatic API charges remains unverified
Monthly and annual billing are different commitments: the annual figure is a prepayment, and an annual equivalent is not a monthly price. Nothing on this page is a test of output quality, and the list below names the official sources this entry uses with the date each was read - check them against the plan and the use you have in mind.

| Price | DocumentedPlus is US$20 per month billed monthly. OpenAI lists Go, Plus, Pro, Business and Enterprise as paid plans and states that they are priced per user per month, with monthly billing for Go, Plus and Business and annual billing for Business and Enterprise; the pricing page we read did not show the plan amounts.Source: OpenAI Help Center - What is ChatGPT Plus? · ChatGPT plans and pricing | DocumentedLists a free tier plus Google AI Plus, Google AI Pro and Google AI Ultra as the paid consumer plans, with availability varying by country.

| Availability | DocumentedOpenAI publishes a supported-country and territory list for ChatGPT on web and mobile. It includes the United States, United Kingdom, Japan and Singapore; access from outside listed regions may lead to an account being blocked or suspended. This is a declared support policy, not a per-plan sales guarantee or a test of local network access.Source: OpenAI Help - ChatGPT supported countries | DocumentedGoogle lists the Gemini web app in more than 70 languages and more than 230 countries and territories, but says mobile availability can differ. Its web country list marks Mainland China as Workspace only. This declared web support does not establish consumer access in Mainland China, eligibility to buy AI Pro or Ultra, or tested local network/account access.Source: Google Help - Gemini web availability |
| Commercial use | DocumentedThe ChatGPT FAQ permits commercial use of outputs, including reprinting, selling and merchandising, for both free and paid plans, subject to OpenAI’s Content Policy and Terms. That permission does not remove the user’s obligations under those policies or establish rights in third-party material.Source: OpenAI Help - ChatGPT commercial outputs | Not establishedPlan-specific output commercial-use conditions were not established by the registered consumer data-use source.Source: Gemini Apps Privacy Hub |
| Training on your data | DocumentedOpenAI states that content from ChatGPT and Codex may be used to train its models; training can be turned off under Data controls or through the Privacy Portal and stops applying to later conversations; temporary chats are not used to train models; submitted feedback may still be used; and Business, Enterprise, Edu and API inputs and outputs are not used for training by default.Source: OpenAI Help Center - how your data is used | DocumentedRead on 12 October 2026. States that activity is used to develop and improve services including generative AI models, that human reviewers read some data, that Keep Activity can be turned off to stop later chats being reviewed or used for training, that activity is auto-deleted after 18 months by default, and that reviewed data is disconnected from the account and kept up to three years. Does not state commercial-use conditions per plan.Source: Gemini Apps Privacy Hub |
| API billing | DocumentedThe API is a separate product with its own billing and is not part of a ChatGPT subscription.Source: OpenAI Help Center - What is ChatGPT Plus? | Not establishedDeveloper API billing through Cloud Billing and paid-key charges are documented, while Google AI plans advertise separate AI Studio and developer-credit benefits.

| Export formats | DocumentedCompleted Deep Research reports in ChatGPT can be downloaded as Markdown, Word or PDF. Deep Research availability and usage depend on the plan, supported country or territory, and workspace permissions. The Word label does not establish a particular filename extension here; the evidence does not cover every ChatGPT surface or verify the correctness of exported reports.Source: OpenAI help — Deep research in ChatGPT | DocumentedGoogle's 29 April 2026 Gemini app announcement lists generated Workspace Docs, Sheets and Slides, PDF, DOCX, XLSX, CSV, LaTeX, TXT, RTF and Markdown files. It says file generation is available to all Gemini app users globally and that most formats can be downloaded or exported to Drive; this is an official capability statement, not a tested export-fidelity guarantee.Source: Google — generate files in Gemini |
| Usage limits | DocumentedPlus subscriptions may include usage limits such as message caps, and those limits may vary with system conditions; because model availability and limits change over time, OpenAI directs readers to the model picker for the options on their account.Source: OpenAI Help Center - What is ChatGPT Plus? | DocumentedLists a free tier plus Google AI Plus, Google AI Pro and Google AI Ultra as the paid consumer plans, with availability varying by country.

What the listings already say
Taken from this site's own entries, so the wording follows the vendors' terms rather than ours; it is our summary of their published material, not their text.
How is Gemini different from ChatGPT?
Both are multimodal assistants with free tiers. API billing and subscription-linked credits require separate checks; this review does not establish Gemini’s complete inclusion matrix. The difference this page can establish is in what the plan pages publish: ChatGPT Plus is listed at $20 a month billed monthly, while Google localises its subscriptions page by country, so the copy read on 10 October 2026 quoted Japan at ¥725 for Google AI Plus, ¥2,900 for Google AI Pro and from ¥14,500 for Google AI Ultra, with no single global price to compare in one currency. On data, both state that consumer activity may be used to train models and both provide a switch that keeps it from applying to later conversations; the pages read here do not set out Gemini commercial-use conditions per tier, and this page does not rank the two.
