Plug and play
Connect your assistant, bring your old tools across, and run it all on one stone.
Your assistant
The one connection that reaches the rest.
Claude
Add Millstone as a connector, sign in and approve. Works in Claude on the web, desktop and phone.
ChatGPT
Add Millstone as a connector, sign in and approve, and ask it about the studio in any chat.
Cursor and Claude Code
Paste one key from your settings, for the people in the studio who already work there.
Any MCP client
Millstone speaks MCP, the open standard, so an assistant that supports it can connect.

Recipes
Leave no stone unturned. One sentence to your assistant, across Millstone and another tool, each run on our own studio before it went on this page.
- Google Calendar and Millstone
Turn last week's calendar into time
“Go through my calendar for last week, match each client call to its project in Millstone, and tell me which have no time logged.”
When we ran it: Matched every work call to the right project, left the personal events out, and found one client call with no time against it.
- Gmail and Millstone
Check what you invoiced by email
“Find the invoices I emailed this month and check each one against Millstone.”
When we ran it: Found an invoice sent by email whose copy in Millstone was still an unnumbered draft, so the inbox and the books disagreed.
- Gmail and Millstone
Find who is missing from your contacts
“Who has emailed me about client work this month who is not in Millstone yet?”
When we ran it: Found a client's assistant writing in about a live project: named in a task, but with no contact record of their own.
Built in
Connected inside Millstone, no assistant needed.
Moving from
Export a file from the tool you are leaving. Millstone recognises which tool wrote it and maps the columns, and your assistant can walk you through it.
Coming
From the roadmap. No dates: a date on a roadmap is a promise made before the work.
Email from your own domainNow
Proposals, invoices and booking emails already carry your name and come back to your inbox. Next they go out from your own address.
Sign in with GoogleNext
Continue with Google on the sign-in page. Access stays by invitation.
Pay by card or transferLater
Clients settle an invoice from its link by card, or by a Wise transfer for international work, and the payment lands on the invoice.
Xero and QuickBooksLater
Send an invoice and its payments to your accounts when you choose, so the books stay in step without retyping.
Dropbox foldersLater
Link a project to a Dropbox folder and its files sit beside the portal's own, without uploading them twice.
E-invoicingLater
Send an issued invoice straight into a client's accounting software over PEPPOL, beside email.
Outlook and iCloud calendarsLater
Booking links read availability from calendars other than Google.
Lighten the load
Early access opens a few studios at a time, each onboarded personally. Put yours forward and put some of the weight down.
