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.

Side-by-side comparison of the selected products. An empty cell means we have not verified that fact here - it is not a statement that the product lacks it, nor that the vendor has not disclosed it.

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	Not establishedThe hub lists Pro $20/month or $200/year and billing help explains web/mobile and local currency. A complete current country/currency/channel-specific purchasable quote is still unestablished; no account checkout was opened.Source: Perplexity hub - cost FAQ · perplexity official per-billing · perplexity official per-local
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	Not establishedOfficial pages link web, desktop, iPhone and Android entry points, but do not establish a full country-distribution and eligibility policy; app links are not proof of access from a country.Source: Perplexity hub - cost FAQ · perplexity official per-export
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	DocumentedRead on 12 October 2026 through a Wayback snapshot of this same URL dated 30 September 2026, because the live page returned a bot check (HTTP 403). Last updated 23 January 2026. Section 5.1 permits use "for your personal, non-commercial use only"; section 5.2 forbids you to "exploit the Services for any commercial purpose, including without limitation communicating or facilitating any commercial advertisement or solicitation". The opening scope states these terms "do not govern use of the Company's APIs" (separate Perplexity API Terms of Service) "or Perplexity Pro for Enterprise" (separate enterprise terms), and section 6.4 states the company "does not claim any ownership in Your Content". So consumer Free/Pro plans are personal, non-commercial, while commercial or business use sits on the separate API or enterprise terms.Source: Perplexity - terms of service
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	Not establishedThe plan table permits training opt-out for Pro/Education Pro/Max and says Enterprise data is not used for training. The privacy-policy body could not be read, so the full training treatment of general Free/Pro inputs and outputs, defaults and exceptions remains unestablished.Source: Perplexity - API privacy and security · Perplexity - privacy notice · Perplexity Help Center - Which plan is right for you?
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 establishedThe API Platform uses purchased credits/auto top-ups and has no complimentary API credits or web/app Pro entitlements. The explicit separate-API statement is in the Enterprise Max section; consumer-subscription API inclusion and all API operation charges remain unestablished.Source: Perplexity - API privacy and security · Perplexity Help Center - Which plan is right for you? · perplexity official per-billing
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	Not establishedAn official Enterprise tutorial documents PDF, Markdown and DOCX answer exports and CSV chart downloads. It does not establish Free/Pro consumer, mobile or every plan’s output-export eligibility, which remains unconfirmed.Source: perplexity official per-export · Perplexity Help Center - Which plan is right for you?
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?	DocumentedThe plan comparison lists Pro Searches at 3/day on Free and weekly limits on paid plans, and Research Queries at 1/month on Free with monthly limits above that. Education Pro prose describes unlimited Pro Searches.Source: Perplexity Help Center - Which plan is right for you?

Official site ↗ Perplexity hub - cost FAQ ↗ What this source supports The public hub lists core search plus Pro pricing/features and web-first products. It does not publish a country-by-country distribution matrix. Historical registered scope read on 2026-09-23, not rechecked in full on 2026-10-15: The cost FAQ states Pro at $20 a month or $200 a year. The same page markets unlimited Pro Search, which conflicts with the plan comparison in the help centre that lists weekly and monthly limits, so the narrower metered wording is kept on this site. The body of the dedicated pricing page was not returned to us and checkout was not tested. Read on October 15, 2026 Perplexity Help Center - Which plan is right for you? ↗ What this source supports Read on 2 November 2026: The individual Pro section lists up to 50 file uploads per project without specifying whether that means cumulative uploads or concurrent files; the plan table lists Free at 3 Pro Searches/day and 1 Research query/month, with weekly/monthly limits for paid individual plans. Education Pro prose says unlimited Pro Searches while the table describes weekly limits. Previously registered scope, not fully reread on 2 November: The plan table labels Pro, Education Pro and Max as permitting training opt-out and Enterprise plans as not used for training. Free is labelled Standard privacy without a complete training rule. API Platform is pay-as-you-go, has no complimentary API credits or web/app Pro entitlements; the explicit API-separate sentence is under Enterprise Max, so it is not broadened to every consumer plan. Historical registered scope read on 2026-09-23, not rechecked in full on 2026-10-15: The plan comparison lists Pro Searches at 3/day on Free and weekly limits on paid plans, and Research Queries at 1/month on Free with monthly limits above that. Education Pro prose describes unlimited Pro Searches. Read on November 2, 2026 Perplexity - API privacy and security ↗ What this source supports Read on 12 October 2026. States a zero data retention policy for the Chat Completions API, that no query data is retained and none is used for AI training, and that API credits are purchased in advance. It does not state whether a consumer subscription covers API usage. Read on October 12, 2026 Perplexity - terms of service ↗ What this source supports Read on 12 October 2026 through a Wayback snapshot of this same URL dated 30 September 2026, because the live page returned a bot check (HTTP 403).

The opening scope states these terms "do not govern use of the Company's APIs" (separate Perplexity API Terms of Service) "or Perplexity Pro for Enterprise" (separate enterprise terms), and section 6.4 states the company "does not claim any ownership in Your Content". So consumer Free/Pro plans are personal, non-commercial, while commercial or business use sits on the separate API or enterprise terms. Read on October 12, 2026 Perplexity - privacy notice ↗ What this source supports Requested on 12 October 2026 and answered with a bot check (HTTP 403). This URL redirects to /hub/legal/privacy-notice; the snapshot of that target dated 29 September 2026 is the text read. It is headed "Last updated: July 8, 2026" and, among data uses, states for the optional Email Assistant that "We do not use the content of emails to create, train, improve, or fine-tune AI models."

How is Perplexity different from ChatGPT?

Perplexity builds its replies from retrieved pages and cites them inline, and separates ordinary searches from metered Pro Search and Research modes. ChatGPT is a broader assistant that also handles writing, coding and image work. We have not benchmarked them, so this page claims no winner.
