The default AI assistant. Check your tier before using client data.
ChatGPT needs little introduction as a general assistant, but the detail that matters for marketers is what each tier actually permits. The paid consumer tiers add deep research, advanced reasoning models, image and video generation, custom GPTs, projects and connectors to tools like Google Drive and SharePoint. Business and Enterprise add admin controls, SSO, shared workspaces and, critically, a different data posture. On the agent side OpenAI now ships an Agents API and a plugin model where you host an MCP endpoint and OpenAI lists it after review. That is worth being precise about: ChatGPT consumes MCP servers, it does not publish one you can call, so despite appearances it does not belong in the MCP filter as a provider. Ads now appear on the free and entry tiers.
Still the default for most people and there is no serious argument against having access to it. The thing we would most want a marketer to take from this listing is not a feature, it is a data point: on the free and consumer paid tiers there is no data processing agreement, and your conversations are used for training by default with opt-out rather than opt-in. Business, Enterprise and the API do not train on your data. If you are putting client material, unpublished campaign work or anything commercially sensitive into ChatGPT, you want Business, and a surprising number of agencies have not made that switch. Two other UK specifics. The UK data residency option covers storage only, not inference, which OpenAI's own UK material does not make clear. And some newer agent features are not available in the UK, EEA or Switzerland at all. On MCP, ChatGPT is a client rather than a server, which several directories get wrong.
Best for: Everyday research, drafting and analysis, with the important caveat that the tier you choose determines whether your inputs train the model.
