Google is about to make talking to Gemini inside Workspace feel a lot less “single use” and a lot more like an ongoing back‑and‑forth you can actually rely on. Starting in March, conversation history is coming to the Gemini side panel in core Workspace apps, so those helpful chats you have in Docs, Sheets, Slides, Drive, and Gmail no longer vanish into the void when you close the pane.

At a basic level, this means you’ll be able to open the Gemini side panel in, say, a Google Doc, see your recent prompts and responses in that app, and pick up exactly where you left off. The scope is intentionally narrow and privacy‑conscious: history is scoped per app and per user. A chat you start in the side panel in Docs will not show up in Sheets, and a conversation you have in the side panel of a shared file is visible only to you, not to collaborators on that document. Conversations stay private to the account that invoked Gemini, even when you’re all staring at the same file.​

Google is rolling this out in stages, and admins get the first controls. As of February 25, 2026, Workspace admins can already configure how conversation history behaves for their organization, including whether people can manually delete their own chats and how long those chats should be retained. End users in Gemini Alpha and Workspace Labs will start seeing history in the side panel from March 3, 2026, with a broader rollout to standard Rapid Release and Scheduled Release domains beginning no sooner than March 17, 2026. That latter wave is labeled as an “extended rollout,” which in Google‑speak means it may take longer than the typical 15‑day window for everyone to see it.

The admin story here matters almost as much as the feature itself. Alongside side‑panel history, Google is introducing two key controls: manual deletion and auto‑deletion. Manual deletion is on by default, so unless an admin turns it off, users can prune their own conversation lists by deleting individual chats from the history view. Auto‑deletion is off by default, with history stored indefinitely unless an organization decides otherwise. If they do enable it, they can set retention windows—such as three months, 18 months, or three years—after which inactive chats are automatically removed. For regulated industries and risk‑averse IT teams, these knobs are essential: you get the productivity boost of an AI that remembers context, without accidentally building an eternal archive of prompts that no one thought about at the policy level.

It’s also notable that this initial Workspace side‑panel rollout deliberately stops short of full e‑discovery integration. Google is explicit that this release does not yet include Vault support or auto‑deletion controls for end users; those will come later. Vault is where legal, compliance, and security teams live, so you can read this as Google moving quickly to ship a user‑facing convenience while promising a second wave that plugs into heavier‑duty compliance tooling. For now, retention is handled by the new conversation history settings, not by Vault retention rules, which will keep some lawyers and admins watching this closely.

From a user’s point of view, the experience should feel like Gemini growing up from a disposable helper into something closer to a long‑term work companion. In the side panel today, Gemini can already summarize long email threads, draft replies, pull out key details from a doc, generate tables and formulas in Sheets, and even suggest images or layouts in Slides. With conversation history, that same panel becomes a place where you can revisit and extend those sessions: ask Gemini to refine the first draft you worked on yesterday in that same document, or continue the spreadsheet analysis you kicked off last week without re‑explaining the context. History only starts populating after the feature goes live for a given user, so anything you did with Gemini before the rollout won’t be retro‑saved into the new view.

There’s also a prerequisite that many people might not realize they’ve already agreed to: to use Gemini in Workspace at all, you need to have Google’s “smart features and personalization” turned on for your account. That’s the same umbrella setting that powers things like smart compose in Gmail or automatic email classifications. Gemini in Workspace rides on top of that, and conversation history does too. If those smart features are off, you don’t get Gemini, and by extension, you don’t get its new memory inside Workspace.

Zooming out, this isn’t happening in isolation. On the consumer side, the standalone Gemini app has already been learning to reference past chats so it can answer questions like “What did we decide for the birthday gift?” or “Summarize our discussions about the solar system,” pulling context from earlier conversations instead of treating every prompt as a cold start. In parallel, Gemini’s reach into enterprise content has grown: it can look across Gmail, Drive, Docs, Sheets, Slides, and now even Workspace Google Chat history to surface project details and synthesize what your team has been talking about. Bringing conversation history into the Workspace side panel is the logical next step—marrying that cross‑app awareness with a persistent, user‑scoped memory inside the tools people live in all day.

On the licensing side, Google is positioning this as a broadly available capability rather than a niche, top‑tier perk. Conversation history in the Workspace side panel is supported across the main business and enterprise SKUs—Business Starter, Standard, Plus, and Enterprise Starter, Standard, Plus—as well as Education Plus, the Teaching & Learning add‑on, Frontline Plus, and AI‑focused add‑ons like Google AI Pro for Education, plus consumer‑oriented Google AI Pro and Ultra tiers. Practically, that means if your organization is already paying for Gemini in Workspace or one of the AI add‑ons, this memory layer is very likely included, subject to admin settings and age requirements. Gemini in Workspace itself remains limited to users over 18 on eligible plans.

For admins, the next steps are fairly straightforward but important. First, you’ll want to review the new conversation history settings in the Admin console under the Generative AI → Gemini for Workspace section, decide whether to allow manual deletion, and set a retention policy that aligns with your data governance rules. Second, you’ll need to communicate to users what this actually changes: their side‑panel chats will start sticking around in each app, they’re visible only to them, and depending on your choices, they may or may not be able to clean up their own history. For users in Alpha programs, this all arrives earlier, so some organizations will effectively be piloting the feature before everyone else gets it.

The bigger story here is philosophical: Workspace is slowly shifting from “AI as a feature” to “AI as a layer that remembers.” Until now, working with Gemini in Docs or Gmail often felt like asking a very capable but amnesiac assistant for help in the moment. With conversation history in the side panel, Google is signaling that it wants Gemini to stick with you from one session to the next, while still honoring enterprise expectations around privacy, admin control, and data lifecycle. If Google can follow through on tighter Vault integration and keep improving how Gemini leverages that history—without turning it into a compliance headache—this could be one of the quieter but more impactful upgrades to how knowledge work happens inside Workspace.
