What you can send

Muffin reads event details in the text of your email and in PDF, JPG, JPEG, PNG, HEIC attachments. Images may be attached or embedded, and a PDF may contain selectable text or scanned pages.

One MB means 1,000,000 decoded bytes. One supported image counts as one page, and one PDF page counts as one page.

Event details Muffin understands

  • Dates, times, and durations
  • Timezones stated in the content or set by a clear venue
  • Recurring schedules, including their end conditions
  • All-day events and deadlines
  • Locations, venues, and joining links
  • Several separate events in one email
  • Optional instructions you write yourself

Where Muffin stops

Unreadable or encrypted files
Muffin explains that the file could not be processed instead of guessing at its contents.
More than 20 calendar items
Muffin does not create invitations for a submission containing more than 20 items. Resend a narrower selection.
Material ambiguity
When a date, time, timezone, or recurrence is genuinely unclear, Muffin creates no invitation and tells you the one detail to add.
Canceling an item you already added
Muffin does not reach into your calendar. A cancellation email tells you what to delete or decline yourself.
Sharing an invite with other people
Muffin replies only to the sending address. Invitations are not sent to anyone else, including recipients found inside forwarded content.
Automatic calendar control
Whether an invitation is placed automatically or needs you to accept or open it is decided by your own email and calendar provider.

When an attachment cannot be processed

Muffin never silently picks the first page or one image out of a bundle that is over the limit. The attachment is not processed, the response says so, and any usable text in the email body is still read. You can resend a smaller selection.

Language

ToMyCal officially supports English at launch. Muffin may understand event information in other languages, but accuracy is not guaranteed.

Try it with something you already have

A confirmation email, a class schedule, or a photo of a flyer all work.
