The short answer
ChatGPT is a broad AI workspace for individual and team work. ChatGPT Business includes shared projects, company knowledge and apps, collaboration, model options, and administration. Nema is a Slack-native coworker. It gives each channel a distinct set of instructions, memory, tools, and approvers.
Choose ChatGPT when teams want a general workspace for research, analysis, writing, coding, and long-running projects. Choose Nema when a task should begin in Slack, remain visible to the channel, and become recurring work without moving the team into another workspace.

Checked September 22, 2026. OpenAI's announcement of shared projects for business plans documents shared files, instructions, and connected team tools. Current plan details should be confirmed on the official pricing page.
A launch review example
A product channel needs to compare launch notes with the approved plan. The inputs include the plan, a supplied release checklist, recent channel decisions, and current customer messaging. The output should identify conflicts and assign decisions without inventing completion status.
With Nema, the team asks in the launch channel. The coworker follows that channel's source rules, checks the records, and posts a review in the thread. A product manager corrects an outdated requirement, and the channel retains that guidance. A scheduled follow-up can revisit unresolved items and report back. A change through a connected app, requested in the thread, waits for approval.
In ChatGPT Business, the team can create a shared project with the plan, files, and project-wide instructions. Members can collaborate across chats while using the same project context. ChatGPT can also draw on configured apps and company knowledge. This is useful when the project needs substantial analysis and artifacts that extend beyond one Slack conversation.
Choose Nema when
Choose Nema when the people responsible for the work already coordinate in Slack. The task stays with the channel's history and membership, and teammates can challenge a source or approve an action without opening a separate workspace. Different channels can maintain different coworker configurations.
Nema also fits organizations that want model choice across vendors or connected actions tied to the requester's app access. Verify the exact model, app, and action in the intended plan.
Choose ChatGPT when
Choose ChatGPT when broad individual and team AI work matters more than a single collaboration surface. Shared projects can hold files and instructions for ongoing work, and ChatGPT supports research, data analysis, writing, code, image, and voice experiences. Business and Enterprise plans add organization controls and connected company knowledge.
ChatGPT is not limited to private one-to-one chats. Shared projects and workspace features support collaborative use. Compare where the team wants the work record and how actions are governed.
Test the handoff
Give both products the same launch plan and one contradictory update. Ask a second teammate to continue the task, correct a requirement, and propose an external change. Observe what context carries over, who can see the correction, and where approval appears.
Also test data access under two users with different permissions. Review how apps enforce source access and whose identity performs an action. Product-wide security statements do not answer those workflow-level questions.
Common questions
Is ChatGPT only for private chats?
No. ChatGPT supports shared projects and workspace collaboration. Members can contribute files and instructions and work from shared context.
Can Nema use OpenAI models?
Nema supports model choice across providers when those models are configured. Its value proposition is not tied to one model vendor.
Can both products use company knowledge?
Yes, through different setups. ChatGPT Business supports company knowledge and apps. Nema uses Slack context and authorized connected sources for the channel's work. Test permissions and freshness against the sources that matter.
