ChatGPT
ChatGPT is OpenAI's general-purpose AI assistant for web, mobile and desktop. It handles conversation, writing, images, voice, file analysis, web research and coding, with a permanent free tier and paid Go, Plus, Pro, Business and Enterprise plans.
What is ChatGPT?
ChatGPT is the conversational AI assistant published by OpenAI. It lives at chatgpt.com as a web application and ships as iOS, Android and desktop apps, while the company's institutional and legal documentation sits on openai.com. The product presents itself around three pillars. Chat covers questions, learning and everyday help: explaining a concept, drafting a message, searching the web, generating an image, comparing options. Work is aimed at finishing tasks rather than discussing them, and creates or edits documents, slide decks, spreadsheets, charts, PDFs and images using the tools, context and apps you already have. Codex is the coding side, described as one agent covering every step from understanding and planning through writing, testing, reviewing and shipping code.
Around those pillars the site advertises named capabilities: Deep Research for long sourced investigations, image generation, Study Mode, Voice and Voice with Video, Shopping, plugins, and conversations held directly with PDFs, presentations and spreadsheets. Connectors reach Microsoft 365, Google Drive, Slack, GitHub, Linear, Figma and Gmail, and in-chat apps include Canva, Spotify and PowerPoint. Optional persistent memory can be reviewed, edited, switched off or wiped, and projects, scheduled tasks and custom GPTs appear from the Plus tier upward. The pricing page captured on 8 August 2026 lists the models by name: GPT-5.6 Luna on the free tier, then GPT-5.6, GPT-5.6 Sol and GPT-5.6 Sol Pro higher up.
Commercially the range runs from a permanent free plan through Go, Plus and Pro for individuals to Business and Enterprise for organisations, alongside ChatGPT Edu for universities, ChatGPT for Healthcare, and ChatGPT for Teachers, free for verified US K-12 educators until June 2027. The iOS listing declares 59 interface languages. On security, OpenAI documents AES-256 encryption at rest, TLS 1.2+ in transit, a 24/7/365 security on-call rotation, a bug bounty and a public trust portal; SOC 2 Type 2 covers the business tiers and ISO 27001, 27017, 27018 and 27701 apply to Enterprise. Notably, the individual plans carry none of those attestations, and no plan price is published in the page's static markup.

When to use ChatGPT / When not to
A quick filter to help you decide if ChatGPT is the right fit.
When to use ChatGPT
- Students and teachers, who get dedicated Study Mode, classroom-oriented workspaces and a free plan for verified US K-12 educators
- Developers and engineering teams, who use the built-in Codex agent to plan, write, test, review and ship code
- Knowledge workers who need finished deliverables, since ChatGPT Work produces documents, slide decks, spreadsheets, charts and PDFs
- Small and growing teams, served by the Business workspace with SAML SSO, MFA, usage analytics and spend controls
- Large organisations with compliance duties, covered by Enterprise controls such as SCIM, EKM, data residency and 24/7 support
When not to use ChatGPT
- Anyone who needs guaranteed factual accuracy, because the terms promise none and outputs may repeat across users
- Teams that must keep data in a named jurisdiction on a budget, since data residency is an Enterprise-only feature
- Buyers who require SOC 2 or ISO certification on an individual seat, as those attestations cover only the business tiers
- Children under 13, who are excluded outright, and under-18s, who need a parent or guardian's permission
- Users in countries under US embargo or sanctions, whom the trade-control clause of the terms excludes
How to use ChatGPT
A typical end-to-end flow, from setup to results.
- Open chatgpt.com in a browser, or install the iOS, Android or desktop app
- Start asking straight away, or create a free account to keep your history
- Type your question, or switch to voice mode when speaking is easier
- Attach PDFs, spreadsheets or presentations and interrogate them directly
- Turn on web search, or launch Deep Research for a long, sourced investigation
- Connect Google Drive, Slack, Microsoft 365, GitHub or Gmail to unlock ChatGPT Work
- Open Data Controls and switch off training if you do not want your chats used to improve models
- Use a temporary chat for anything sensitive; it is deleted automatically within 30 days
- Upgrade to Go, Plus or Pro from the pricing page when you hit the usage limits
- For a team, open a Business workspace from two seats up, or contact sales for Enterprise
Pros & Cons
Pros
- A permanent free plan rather than a countdown trial
- Unusually broad coverage for one subscription: text, voice, images, files, web and code
- Available on web, iOS, Android and desktop, with 59 declared interface languages
- Granular privacy controls: temporary chats, a training opt-out, memory management, export and deletion
- Compliance paperwork actually published: DPA, sub-processor list, trust portal and transparency reports
- SOC 2 Type 2 on the business tiers and ISO 27001, 27017, 27018 and 27701 on Enterprise
- Data residency offered across ten regions for Enterprise customers
Cons
- No individual plan price is readable in the page markup: amounts are injected client-side and vary by country
- No support email address at all; every request goes through the help centre
- Individual plans get neither data residency, nor SOC 2, nor ISO certification
- Advertising is being tested in the United States on the Free and Go plans
- Consumer conversations feed model training by default, and the opt-out is yours to find and switch off
- Third-party contractors may read content when reviewing for abuse and misuse
- The ISO certificates stop at Enterprise and do not extend to Business
Pricing & Plans
There is a permanent free plan, open to everyone and not a time-limited trial. Paid tiers are priced per user per month: Go, Plus and Pro for individuals, Business and Enterprise for organisations. The individual plan prices could not be established: the pricing page renders its amounts client-side and localises them by country, so no figure appears in the delivered markup. The only amount we could read is ChatGPT Business at USD 25.00 per user per month billed monthly, taken from a footnote on OpenAI's business pricing page; the same page, requested from Switzerland, displayed CHF 15 per user per month billed annually with a two-seat minimum. Business is an organisation tier, not the cheapest paid entry point. Enterprise is quoted on request, with credit-based and token-based options available.

Data, GDPR & hosting
A consolidated view of how ChatGPT handles your data.
GDPR overview
GDPR implementation is documented rather than merely claimed. A dedicated European privacy policy names OpenAI Ireland Limited, Dublin, as the controller for the EEA and Switzerland, which means the publisher has an establishment inside the Union. A Data Protection Officer is appointed and reachable at dpo@openai.com; access, deletion and portability requests go through privacy.openai.com or dsar@openai.com. A Data Processing Addendum can be executed for Business, Enterprise and the API, standard contractual clauses are annexed to it, and a sub-processor list is published with an email subscription for change notices. Transfers outside the EEA are covered by safeguards, a copy of which is available on request. Data from children under 13 is not knowingly collected.
Who owns the data?
You keep what you bring and what you get back. The terms state that you retain ownership of your inputs and own the outputs, and OpenAI formally assigns to you whatever rights it might otherwise hold in them. In exchange, OpenAI may use your content worldwide to provide, maintain, develop and improve its services, comply with the law, enforce its policies and keep the service safe. Human review is possible: authorised employees, and third-party contractors bound by confidentiality, may read content when investigating abuse or misuse. On Business, Enterprise, Edu, Teachers and the API, customer data is not used for model training by default, and workspace administrators can view, export and delete members' conversations.
Reuse rights
Reuse is broad and explicit. Because OpenAI assigns you its rights in the output, you may use what ChatGPT produces without asking further permission, including commercially. Three limits matter. Outputs are not guaranteed to be unique, so another user may receive something very similar, and the assignment does not extend to other users' outputs or to content returned by third-party services. You may not present an output as human-written when it is not. And you may not use outputs to build models that compete with OpenAI, nor extract outputs programmatically. Sharing published content is further governed by the Sharing and Publication Policy, while Enterprise and API use falls under separate business terms.
Data retention & training
Hosting summary
OpenAI publishes a sub-processor list, last updated 9 July 2026. Cloud infrastructure comes from Microsoft Corporation, which alone declares processing across 23 countries, plus Amazon Web Services, Google Cloud Platform, Oracle Cloud Infrastructure and CoreWeave. Cloudflare provides content delivery and web hosting, processing at whichever data centre is closest to the end user. Within the group, data is handled by OpenAI OpCo LLC and OpenAI LLC in the United States, OpenAI Ireland Ltd in Ireland, OpenAI UK Ltd in the United Kingdom and OpenAI Japan Ltd in Japan. Data residency is an Enterprise feature, offered across ten regions - the US, EU, UK, Japan, Canada, South Korea, Singapore, India, Australia and the UAE - and unavailable on Free, Go, Plus, Pro and Business. Data is encrypted with AES-256 at rest and TLS 1.2+ in transit, and transfers out of the EEA rely on contractual safeguards available on request. One caveat on the network trace: the domain resolves to a Cloudflare anycast address, which marks a point of presence, not a place where anything is stored.

Things to keep in mind
Risks and trade-offs to weigh before adopting ChatGPT.
- Dependence and cognitive off-loading: used as a substitute for thinking rather than a support for it, the tool quietly erodes the skill it was meant to assist
- Confident errors: outputs can be fluent and wrong, and nothing in the terms guarantees accuracy, so anything that matters needs checking
- Training on by default for consumers: conversations feed model improvement until you go into Data Controls and stop it
- Human eyes on sensitive confidences: authorised staff and third-party contractors may read content when reviewing for abuse and misuse
- Persistent memory accumulates personal detail across sessions; review and purge it periodically or switch it off
- Ad personalisation, now being tested on Free and Go in the United States, is another profile to keep under control
- An account opened with a work email address can be absorbed into your employer's workspace, whose administrator can then reach your content
Setup & Integrations
Technical difficulty
Effectively none for an individual. Open chatgpt.com and start typing; you can use it without an account, or create a free one in seconds, and the iOS, Android and desktop apps are optional installs. Real effort only appears at the organisation tiers, where a Business or Enterprise workspace involves SAML SSO, MFA and, higher up, SCIM provisioning, encryption key management and domain verification - work for an IT administrator rather than an end user. App connectors add a small ongoing step: each one is authorised separately, and every user authenticates against the connected service before use.

Should you pick ChatGPT?
ChatGPT is the broadest assistant in this directory, and that breadth is the point: one subscription covers conversation, writing, images, voice, file analysis, web research and software engineering, on web, mobile and desktop, in 59 declared interface languages. The free plan is permanent rather than a countdown, which makes the tool unusually easy to evaluate before committing.
The reservations are worth stating plainly. No individual plan price could be established. The pricing page renders its amounts client-side and localises them by country, and the single figure we could read - USD 25.00 per user per month for ChatGPT Business - belongs to an organisation tier, not to the cheapest paid entry point. Anyone budgeting should check the price from their own country before deciding.
The privacy picture is two-speed. Business and Enterprise customers get a published DPA, a sub-processor list, SOC 2 Type 2, ISO certification on Enterprise, data residency across ten regions and no training on their data by default. Individual subscribers get none of those attestations, have training switched on by default, and are the ones seeing advertising tested on the Free and Go plans. The controls to fix that exist and are genuinely granular - temporary chats, a training toggle, memory management, export and deletion - but they must be found and used.
Two practical notes. Support runs exclusively through the help centre; no support email exists, so expect self-service. And the product moves fast: the model names, tiers and limits recorded here come from pages captured in early August 2026, and are the first things likely to have changed by the time you read this.
