Multi Calendar

Connect personal Outlook.com and Hotmail calendars to Claude alongside work Microsoft 365 and several Google accounts, each signed in with its own provider - one connector, one search for free time across all of them.

Ask in plain words: what's on this week across all my calendars, find an hour free everywhere on Thursday, move my 3pm to Friday, accept Anna's invitation. Claude reads events, finds free time, creates, moves and cancels events and answers invitations. Invitations go out from your own address, through Microsoft or Google.

A booking link offers one guest the times Claude picked. A booking page at lumman.co/book/your-name lets anyone book a time that is free within your working hours. A group poll lets several people tick the times that suit, then Claude books one. Guests need no account and see each time in their own zone beside yours.

A circle finds time with colleagues or family who also use Multi Calendar - each member shares only when they are busy, never what an event says. Busy everywhere shows busy time from one account as private blocks in another, so a work calendar knows when your personal one is taken.

Seeing events, changing events, and inviting and replying are switched on separately for every calendar account.

Lumman keeps no copy of your calendars. Events are read from Microsoft or Google when Claude asks, and the words of every event - an invitation from a stranger included - are screened for prompt attacks by Google Cloud's Model Armor before they reach Claude. Microsoft lists Lumman Ltd, London, as a verified publisher.

Free for every calendar, with one booking page and one circle; a plan adds more of both.
