ChatGPT is the most widely used AI assistant in the world, but “using ChatGPT at work” covers very different realities — from the employee logging in with a personal account to a company-wide ChatGPT Enterprise rollout with privacy controls, centralized administration, and connections to the organization’s systems.
ChatGPT options for business
ChatGPT Free / Plus (individual accounts): fine for personal exploration. The free version gives no guarantees that your data won’t be used for training. Not recommended for confidential company data.
ChatGPT Business: built for teams of 2 to 149 people. Conversation data isn’t used to train the models. Includes OpenAI’s most advanced models, image generation, and access to custom GPTs. A good fit for teams that want to start with basic privacy guarantees.
ChatGPT Enterprise: for organizations with more than 150 users. Adds SSO, centralized user management, a larger context window, usage analytics by department, and a data processing agreement (DPA) for GDPR compliance. Your data is never used to train models.
The most productive use cases at work
Drafting and polishing communications. Sales proposals, client emails, internal reports, executive presentations. In an experiment with 453 professionals published in Science, those who used ChatGPT finished their writing tasks 40% faster and quality rose 18% (Noy and Zhang). In a company setting, the effect depends on clear instructions and human review.
Document analysis and information extraction. Upload a contract, a financial report, or a technical document and ask for a summary, a list of problematic clauses, or the key figures. With OpenAI’s most advanced models and Enterprise’s extended context, this works on documents of up to hundreds of pages.
Coding assistant for technical teams. Writing, reviewing, and debugging code. On well-scoped programming tasks, a controlled experiment measured 55% less time (GitHub). With experienced developers working on their own codebases, however, another study measured 19% more (METR). The effect depends heavily on the type of task.
Meeting prep and information synthesis. Summarizing meeting transcripts, pulling out action items, and producing formatted minutes.
Custom GPTs (available on Business and Enterprise): assistants built around the company’s style, terminology, and documents. A GPT set up as “expert on product catalog X” answers with the precision of someone who knows the product inside out.
Privacy and GDPR: what you need to know
OpenAI is based in the US, which raises GDPR considerations for transfers of personal data. ChatGPT Enterprise includes a DPA that covers transfer safeguards. For especially sensitive data (health, regulated financial data, information about minors), we recommend models deployed on your own infrastructure or within the EU.
Frequently asked questions
Can employees use their personal ChatGPT accounts for work? It’s a security and privacy risk that company policy should address. Data shared through free personal accounts may be used to train models. We recommend providing corporate access with the right safeguards.
Is ChatGPT Enterprise GDPR compliant? OpenAI offers a standard GDPR-compatible DPA for Enterprise. Where EU data residency is required, there are alternatives such as Azure OpenAI Service, which hosts the models within Europe.
How do we measure the ROI of rolling out ChatGPT? The most common metrics are hours saved per employee, less time spent drafting documents, team satisfaction, and output quality. ChatGPT Enterprise’s usage tracking by department makes this analysis easier.
