How to Connect Multiple Google Drive Accounts to Gemini
Every Gemini surface reads exactly the Google account you are signed into, and Carly is what puts a second one in the same conversation. No control anywhere in Gemini adds another identity, and multiple sign-in switches which account is active rather than federating them. Connect each Drive to Carly, add Carly to Gemini as a custom app, and one question can cross a personal Drive and a Workspace Drive. Carly holds your OneDrive accounts, and every mailbox and calendar on both sides, in the same place.
What one chat can do afterwards
- Search a personal Drive and a work Drive in the same request.
- Find every copy of a document, whichever account it lives in.
- Report the source account on every row of a result.
- Save a file to the account and folder you name.
- Rename and file incoming client documents to your convention.
- Start the work when a file lands, not when you next ask.
Nothing is merged. Each Google account keeps its own authorization and stays individually addressable.
1. Sort your accounts
| Your case | Reachable in one Gemini chat |
|---|---|
| Several folders in one Drive | Yes, no setup |
| Personal Gmail Drive plus a work Workspace Drive | Only through Carly |
| Two Workspace domains, two employers | Only through Carly, and each administrator approves separately |
| A client’s folder shared into your account | Yes, as shared files |
| A Project shared with your own second account | No, the collaborator still needs Drive permissions on the files |
That last row catches people out. Sharing a Project does not carry file access with it, so pointing your second account at a Project gives it nothing that account could not already open.
2. Connect each Google Drive account to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Google Drive and click Connect.
- Authorize the first Google identity.
- Repeat for every other account, choosing Use another account when Google preselects the first login.
- Confirm the full address after each authorization.
Personal and Workspace accounts sit side by side. If a Workspace account needs administrator review, ask that administrator to approve it, then finish authorizing.
3. Add Carly as a custom app in Gemini
- Go to gemini.google.com on a computer.
- Open Settings & help → Connected Apps.
- Under Custom apps for Spark, click Add a custom app.
- Enter
https://carlyassistant.com/mcp/. - If prompted, open Show more under Advanced features to enter credentials.
- Click Next and follow the on-screen instructions.
Google gates the custom apps channel. It needs a personal Google Account, since the feature “isn’t available if you sign in with a work or school Google Account,” plus being 18 or over and in the US, with Keep Activity switched on. Support has rolled out unevenly across Spark’s surfaces and tiers, so if Add a custom app is missing, check your plan and platform against Google’s availability documentation before assuming the connector is broken.
The personal-account rule does not block this setup. You sign in to Gemini personally and Carly holds the Workspace identities, so work files arrive through Carly rather than through Gemini’s own Google connection. Google notes that it does not control or secure third-party MCP servers and asks you to understand what a server does first: Carly’s actions are the Drive operations you authorized per account, revocable at carlyassistant.com/integrations.
4. Test each Drive read-only
One account per prompt until the routing is reliable:
In my personal Drive, find the newest signed PDF and give me the filename and date. Do not change anything.
In my work Drive, list every document added to the Databricks folder in the last two weeks. Read only.
Then the question that needs both at once:
Find every copy of the current rate card across both my Drive accounts, tell me which account each lives in, and flag any that disagree on price.
5. Reuse this routing prompt
Treat my personal Google account as Personal and my Workspace account as Work. Always state the target account and folder before saving, renaming or moving a file. Never write to an account I have not named.
Then name the target per action:
Save the countersigned agreement to the Work Drive under Clients/Adobe, and leave a copy in the Personal Drive archive folder.
Where Gemini’s own Drive reach stops
There are two doors into Drive on Google’s side, and they can do different things to your files, which is why advice on this contradicts itself.
Door one is the Gemini app with the Google Workspace app switched on in Connected Apps, covering Gmail, Calendar, Docs, Drive, Keep and Tasks together. Google’s list of what Gemini cannot do there is blunt: it cannot access pictures and videos in your Drive, cannot create, draft or delete spreadsheets, PDFs, documents and presentations, and cannot manage content in your Drive, such as creating folders or moving content between folders.
Door two is Ask Gemini inside drive.google.com, with a side panel of Sources, Projects, History and Gems. This door does organize files: Google’s Drive help documents a Suggest file moves flow where Gemini will suggest moving files into existing folders or creating new ones. It needs Editor access, runs on Drive on the web, is English only, and Google states plainly that it will not move any files without your permission. Both statements are current, and any advice that says flatly “Gemini cannot organize your Drive” is half right.
Neither door has an add-an-account control. The Gemini app reaches Drive only through the Google Workspace app, whose requirement is that you are signed in to the same account you use with Google Workspace. A personal account’s Gemini never sees your Workspace files, and a work or school account is a separate, administrator-gated product where Workspace apps can be turned off entirely.
Two more limits shape what you get inside one account. Sources must be Docs, Sheets, Slides or PDFs, and you need view permission on each. And files Ask Gemini produces land in My Drive root rather than the folder you were working in, which quietly scatters output.
Sharing a folder in from the other account is the one native cross-account route, and it is permission rather than connection. It works, and it is a list you maintain by hand forever, with a Workspace administrator on either side able to switch external sharing off and end it.
On triggers, be precise: Gemini’s scheduled actions cover time-based schedules, Gmail monitors that run a task when an email matching a Gmail filter arrives, and topic monitors. Gmail monitors are genuine event triggers, so it is wrong to say Gemini has none. There is no Drive monitor. Nothing starts when a file lands in a folder, which is the whole problem if your work arrives as a stream of client files.
Gemini versus Carly on Drive
| Need | Gemini | Carly |
|---|---|---|
| Search the signed-in account’s Drive | Yes | Yes |
| Summarize a long PDF in place | Yes, natively in Drive | Yes |
| Suggest folder moves inside one Drive | Yes, via Ask Gemini with Editor access | Yes |
| Hold a personal and a Workspace Drive at once | No | Yes |
| Answer one question across both accounts | No | Yes |
| Start work when a file lands | No, Drive has no monitor | Yes |
Carly authorizes per identity, several at once, personal and Workspace together, so one question spans both without anyone sharing a folder to anyone. It also fires on the event: a file lands in the client folder, it gets read, renamed to your convention, filed in the right place, and summarized to the person who needs it.

Quick fixes
| Problem | Fix |
|---|---|
| Add a custom app is missing in Gemini | Confirm a personal Google Account, US location, English, and Keep Activity on |
| The Google Workspace app will not connect | Check Keep Activity is on and smart features in other Google products is enabled |
| A work account shows nothing | An administrator may have turned Workspace apps in Gemini off; connect it at carlyassistant.com/integrations instead |
| A file will not attach as a source | Sources must be Docs, Sheets, Slides or PDFs, and you need view permission |
| Gemini will not move files for you | File moves are an Ask Gemini feature in Drive on the web, and need Editor access |
| Generated files vanish | Ask Gemini saves output to My Drive root, not your working folder |
Frequently asked questions
Can Gemini access two Google Drive accounts at once?
Not on its own. Both the Gemini app and Ask Gemini in Drive read the account you are signed into, and there is no control to add a second. Connecting each account to Carly and adding Carly as a custom app is what makes both reachable from one chat.
Can Gemini see my work Drive from my personal account?
No. The Gemini app reaches Drive through the Google Workspace app, and Google requires you to be signed in to the same account you use with Workspace. Work and school accounts are a separate product an administrator controls.
Can Gemini move or organize files in my Drive?
It depends which surface you mean. The Gemini app cannot create folders or move content between folders, but Ask Gemini inside Drive on the web can suggest file moves and create folders, with Editor access, and will not move anything without your permission.
How do I get a second account’s files into Gemini?
Connect that account to Carly and add Carly as a custom app. Sharing folders across also works and stays a manual list you maintain, with only the files you remember to share.
Does Gemini do anything when a file arrives in Drive?
No. Gemini’s scheduled actions cover time-based schedules, Gmail monitors that fire on an incoming email, and topic monitors. There is no Drive equivalent, so a new file starts nothing.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
