For anyone who has ever manually switched Google accounts mid-conversation with an AI assistant, this update is the one you actually wanted. OpenAI has updated ChatGPT and Codex to support multiple Gmail, Google Calendar, and Google Contacts accounts within a single workspace, ending a restriction that had been a genuine pain point since the connectors first launched in mid-2025.
The change was confirmed by OpenAI DX engineer Gabriel Chua. It applies to Plus, Pro, Business, and Enterprise plans. Before this, users were capped at one connected Google account per workspace. That meant anyone managing a personal inbox alongside a corporate Google Workspace calendar had to either pick one or keep signing in and out. Not exactly what you want from a tool that’s supposed to reduce manual work.
Setting it up is straightforward. In the left sidebar, users open the Plugins or Connectors section, find Gmail, Google Calendar, or Google Contacts, and hit the gear icon to add a second or third Google profile through standard Google authorization. Once connected, the assistant can pull context across all linked accounts without merging them. So you can ask ChatGPT to scan your personal archive for a receipt while also checking your corporate calendar for open meeting slots, all in one prompt.
This matters beyond convenience. The request for multi-account support had been building on community forums and GitHub repositories for months, particularly from developers using Codex who needed cleaner identity boundaries between clients or projects. OpenAI has acknowledged that similar requests exist for Slack, Microsoft 365, and Google Drive, though those remain open for now.
- Gmail: search across personal and work inboxes in a single query
- Google Calendar: check availability across multiple calendars at once
- Google Contacts: pull contact details from different organizational profiles
On the security side, OpenAI is clear that connected accounts stay bound by their original app permissions. Corporate Google Workspace admins can still restrict or block third-party integrations based on internal policy. That’s an important note for enterprise buyers, because the flexibility here doesn’t mean your company’s data governance goes out the window.
Compared to where the product was a year ago, this is a meaningful step forward. Tools like Microsoft Copilot and Google’s own Gemini have had tighter native integration with their respective productivity suites from the start, which gave them a natural edge for users already in those ecosystems. This update helps close that gap for ChatGPT. It won’t flip any decisions on its own, but for power users already invested in OpenAI’s tools, it makes the daily workflow significantly less annoying.
