No More Doodle extension by Benjamin Piwowarski

No More Doodle fills in scheduling polls for you, using the events already in your calendar.

Open a poll, and the extension lays your calendar side by side with the poll's time slots: a calendar view on a shared time axis, and a list view spelling out exactly which events clash with each slot. Every slot gets a proposed answer, you adjust anything you disagree with, and one click fills the whole form.

Supported scheduling sites:

• Doodle (doodle.com)
• Evento (evento.renater.fr)
• Framadate (framadate.org)
• Timeful (timeful.app)
• Rallly (app.rallly.co)

You choose which calendars are consulted, and what each one means: a calendar can mark a slot as unavailable, as "if need be", or be ignored entirely. The most restrictive answer among the events overlapping a slot wins.

Requires macOS. Calendar data is read locally through a small native bridge that talks to the macOS Calendar (EventKit) framework, and is installed separately - see the project homepage for setup instructions. Your calendar never leaves your machine: the extension makes no network requests with it.

Reading Thunderbird calendars is being considered, which would lift the macOS requirement.
