Cal Me Maybe

Selected text in, calendar events out.

Cal Me Maybe is a Chrome extension that turns text you select on any web page into an event in your Google Calendar. Highlight a date, a meeting time or an invite in an email, press a shortcut, and it becomes a calendar entry with the title, time, location and description already filled in.

You're reading an email that says "let's do the design review next Tuesday at 2, my office". Highlight it, press a shortcut, and there's a "Design review" event on Tuesday at 2pm with the location filled in and the email quoted in the description.

It works on anything selectable — a message in a web chat client, a line in a shared document, a paragraph of a conference agenda.

Three ways to capture

Magic Alt+Shift+C

The event is created straight away. For text that's already unambiguous.
Quick Alt+Shift+Q

A small box appears so you can add context first — "make it 30 minutes", "invite sam@work.com" — then the event is created.
Chat Alt+Shift+X

A side panel describes exactly what it will create, and nothing happens until you approve. Ask for changes as many times as you like.

Which model reads the text

You choose. Chrome's built-in AI runs entirely on your own machine, so the text never leaves your computer and there's no key to manage. Alternatively you can supply your own Anthropic, OpenAI or OpenRouter API key, which handles messier text and awkward relative dates more accurately. You pay that provider directly — there is no service in between.

What data Cal Me Maybe requests from Google, and why

Cal Me Maybe asks for the minimum access needed to put an event on your calendar, and uses it for nothing else:

See, edit, share and permanently delete all the calendars you can access using Google Calendar (calendar.events) — used only to create the events you have asked for. Cal Me Maybe does not list, read, modify or delete your existing events. This is the narrowest scope Google offers that permits creating an event.
See your primary Google Account email address (email) — used only to show you which account an event is about to be created on, so you can confirm it is the right one before anything is written.

Events are written directly from your browser to Google. There is no Cal Me Maybe server, no account to create, and no analytics. Your Google data is never sold, never used for advertising, and never used to train a model. Full detail is in the privacy policy.

Installing

Install from the Chrome Web Store, or build it from source.
Open the extension's settings and click Sign in with Google.
Pick a model provider. Chrome's built-in AI needs no setup; for the others, paste an API key.
Select some text on any page and press Alt+Shift+C.
