Most agencies looking at Multiply already pay for ChatGPT, and it is a strong assistant. This comparison, checked in October 2026, covers what each is built for, where they differ in agency work, and when staying on ChatGPT is the right call.
Multiply is an agency operating system. Every client gets a workspace that keeps its briefs, files and call transcripts together, and three always-on agents (Account Manager, Planner and Project Manager) work from that context, on a schedule as well as on request.
Choose Multiply when client work has to stay sorted by client and keep moving between briefs.
ChatGPT Business is OpenAI’s shared workspace for teams: chat, the ChatGPT Work agent, shared projects, Spaces and more than 1,400 plugins, with apps in Slack, Microsoft Teams and Office.
Choose ChatGPT when you want one capable assistant for everyone, on every kind of task, at a known seat price.
ChatGPT Business is a real, working setup, so this compares it as one. The rows that matter most to an agency are client separation, shared context and where the data sits.

In ChatGPT, context lives with a person or a project: their memory, their chats, the files they uploaded. When the strategist who knows the account is away, the next person starts cold.
In Multiply every client has a workspace. Brand guidelines, strategy, call notes and past work sit there once, and every project and task under that client reads from it, whoever runs it.
The Multiply recorder joins Meet, Zoom and Teams calls, and each transcript is saved to the right client’s workspace, where the next brief and every agent can use it.
ChatGPT’s Meetings plugin is a beta in the Mac desktop app. It writes notes into the attendee’s own Space, and getting them into a shared client project is a manual step.
ChatGPT now runs scheduled and team tasks, and they work well once someone sets each one up.
Multiply starts from the client instead. Every client workspace gets weekly brief proposals and client news with no setup, and Workflows take any other recurring job, from the competitor scan to the Monday status note, on the cadence you choose.
“I find that it's much better than ChatGPT. The answers are deeper and more professional.”
“I just used Multiply to get some creative thought starters, and man, I was pretty blown away...Whenever I’ve tried this in the past with ChatGPT, they have been pretty average, corny and generic, but this time felt different. I’m kinda in shock. They obviously aren’t final by any means but about 6/10 have some serious legs to them if we refine them.”
“Multiply works great. The real power of Multiply lies in having a shared place for the entire organization and the team. The UX is very inviting and straightforward, and as someone who does a lot of research and tests different strategic angles, I find that I get good results.”
“I was able to execute a short proposal in around 30 minutes… I shared a first draft with the team and they had no notes.”

For agency client work, yes. Multiply replaces the shared projects, prompt libraries and one-off scheduled tasks agencies build on ChatGPT with a workspace per client and agents that work from it. For general individual work, many agencies keep ChatGPT as well.
Yes. Connect Multiply to ChatGPT through MCP and ChatGPT can search your Multiply workspaces, projects, tasks and files, citing where each answer came from. You can also import your ChatGPT memory into your Multiply profile. Plenty of agencies keep a general assistant for individual work and run client work in Multiply.
It does, and they are good. The difference is what they belong to. A ChatGPT project or task belongs to the people who set it up. A Multiply workspace belongs to the client, and its context, calls, schedules and agents stay with it when the team changes.
OpenAI announced in September 2026 that custom GPTs are being retired and moved to plugins, so many agencies are rebuilding them anyway. A good GPT is a good specification: in Multiply it becomes an agent the agency owns, shared by everyone and improved in one place.
ChatGPT Business costs $20–25 per standard seat a month and $100–125 per premium seat; Enterprise is priced on request. Multiply is priced for the size and shape of your team after a walkthrough, and onboarding is done with you: we scope your workflows and build your first agents together.
ChatGPT Business doesn’t train on your data and has a SOC 2 Type 2 report; EU data residency needs ChatGPT Enterprise. Multiply keeps data in the EU and never uses it to train models. It isn’t certified yet: it works in line with GDPR, SOC 2 and ISO 27001 and monitors compliance continuously. The detail is on the security page.
