Turn Outlook calendars into paste-ready availability lists

Booking links make people schedule for you. OpenSlot hands them your free times instead. Pick people, a timezone and a window; it reads Microsoft 365 free/busy (read-only, nothing stored) and returns one clean, paste-ready list of every slot everyone is free. Works on the web and inside Outlook: insert into the email you're writing, or open it on a received message and hit Reply with times. Working hours, minimum slot and weekends are remembered. Free plan, 14-day Pro trial, no card.
Hi Product Hunt! I'm Jonathan, and I built OpenSlot because I was tired of typing "how about Tuesday at 3" and then eyeballing three people's calendars to check.
Booking links solve this by making the other person do the work. I wanted the opposite: hand them my free times, in plain text, inside the email I'm already writing.
OpenSlot reads Microsoft 365 free/busy (read-only, nothing stored), merges the people you pick, and gives you one paste-ready list in any timezone. It's an Outlook add-in and a web app. In compose it inserts at your cursor; open it on a received email and "Reply with times" opens a reply with your availability already in it.
It went live in Outlook's add-in store this week (search "OpenSlot" under Apps). Every account starts with 14 days of Pro, no card.
I'd love to hear what's missing. Which calendars should it read next?
