ChatGPT handles conversational writing, brainstorming, planning, summarization and analysis, with web search that cites current sources, file uploads and analysis, image input and generation, and deep research for multi-step research with cited structured reports, with usage and availability varying by plan. Projects organize chats, files and context under a shared objective, and shared projects can serve as context hubs for ongoing work. Scheduled Tasks are available to some users for one-time or recurring future tasks. On eligible plans, ChatGPT Work can work across apps and files to create finished materials such as documents, presentations, analyses and sites, and connected apps and plugins can bring external tools and information into the workflow, with availability depending on plan, region, workspace, role and permissions. Voice capability exists on paid plans, with exact modes and limits varying. Business plans add connections to Google Workspace, Slack, GitHub, Microsoft 365 and more, along with SAML/SSO/MFA, centralized billing and admin, usage analytics and spend controls, and no training on business data by default. Model availability and limits change over time, so plan-level wording matters more than any single model name.
