Before you start.
A Google account with Gmail. Work accounts may require administrator approval.
What you can do
- Search and read mail threads, with recent mail indexed locally.
- Read selected file attachments up to 10 MB. Create drafts, draft a reply within an existing thread, or send a message after approval.
Connect Gmail.
Find Gmail in Doppel.
Open Settings → Integrations → Add integration. Select Gmail, then Connect.
Choose the services you want.
In Connect Google, enable Mail. Mail, Calendar, and Drive share an account connection; leave any services you don’t want turned off.
Choose your Google account.
Sign in to the account whose information you want to use. Review Google’s requested permissions and approve your selected services. A work account may need administrator approval.
Return to Doppel.
Finish the browser authorization, then return to Settings → Integrations. Check that access was granted before trying the example below.
Choose what to remember.
With Pro or the trial, use Manage sources to remember selected content and assign it to a project. This is an additional, separately authorized connection.
Open Manage sources.
Go to Settings → Integrations → Manage sources. In Selected sources, choose Add account. This is separate from Add integration.
Add the source account.
Select the service and give the account a label. Sign in to the account that owns the source, or approve macOS access for Apple Calendar and Reminders. This account is stored separately from your primary integration connection.
Choose where the source belongs.
Select Choose source. Set Use in to the intended Doppel project, or All-work chats only. A source assigned to one project cannot be requested from another project’s chat.
Select what to remember.
Choose the Gmail label you want to import.
Check the import.
Choose Add source, then inspect its coverage and Last complete sync. Use Sync now to refresh it. Ask a question in the project you assigned, or an All-work chat if you chose All-work chats only.
What this imports
Original message bodies from the selected label. Completed scans reconcile edits, moves, and deletions. File attachments are read individually when requested, not imported in bulk.
Check each source’s coverage and Last complete sync. If access becomes unavailable, the source is excluded from answers until a complete sync succeeds.
Start with something you know
Check the connection.
Find the email thread about the Harbor launch deadline.
Use a subject you know exists. Open the source and check the sender and thread. Try a draft before sending anything.
Data and permissions.
Recent mail is downloaded and indexed on your Mac. Live searches go to Google. Saving a draft or sending mail sends the selected message content to Gmail.
Current limits
Local indexing is not an instant copy of your entire mailbox. Mail, Calendar, and Drive permissions are chosen separately.
Disconnect or change access.
Disconnecting any Google service disconnects the whole Google account: Gmail, Calendar, and Drive. Doppel removes locally indexed Gmail and stops requests through that Google connection. Calendar context already saved, retained chats, and exported files are separate. An account also connected through Apple Calendar can still supply events. To change selected services, use Change access instead; revoke the app in Google account settings if you also want to remove its provider-side authorization.
Selected-source accounts are separate. In Manage sources, remove an individual source or disconnect its account to remove those imported copies and credentials. Disconnecting the primary integration alone does not remove a separately authorized source account. Provider originals, saved chats, and exports are managed separately.
If something isn’t working.
Connected, but a recent message is missing
Check Mail is selected, inspect the sync status in Settings → Integrations, and try a live Gmail search with the exact subject.
Google blocks the connection
Confirm the account is included in your beta access. For an organization policy restriction, ask your administrator; for an app availability warning, contact Doppel support.
