Calendar Pro
A small AI model that runs entirely on your PC. It turns a day's notes and events into a short diary entry, the week into a draft status email, a project's events into a plain-English summary, and a rough event title into a clean one. Nothing leaves your computer, and nothing changes until you click Copy, Append or Use this title. Part of Calendar Pro.

In Day view, click AI diary entry next to Day notes. The entry appears below; Copy it or Append it to the notes.
Choose Weekly update (AI) in the ··· menu for a draft email with a subject line, from the week's notes and events.
In Project Report, AI summary describes where the project is - the totals stay as Calendar works them out.
Click ✨ next to an event's title for a clean, short version. Use it, or dismiss it.
Calendar Pro help has every option in detail.
