Most calendar apps want a form for every event: title, date picker, start time, end time, calendar, save. For a week full of small meetings that adds up, and the tasks that come out of those meetings end up in a different app. osFoundry has a Calendar and a Todos screen side by side in the same desktop app, and both take plain sentences.
Calendar: one line instead of a form
osFoundry is a desktop app that puts chat, agents, files and tools in one window. The Calendar screen has the usual header (Today, back and forward, the date, a view switcher and + Create) plus Booking links, Polls, notifications, settings and print. Right under it is the quick-add bar.
You type the event the way you'd say it, for example "Meeting next Tuesday 3pm", and press Add. osFoundry turns the sentence into a proposed event with a title, start and end, and one click creates it. With your own model key in the desktop app, the parsing uses that model, which handles relative dates, durations and attendees well. Without one, a built-in parser that doesn't use a model still handles the common cases.
The sidebar lists your calendars under My Calendars, each marked Private or Workspace, so a focus-time calendar stays yours while a launch calendar is shared with the team. Add calendar creates another one, and Connect external links calendars you already use elsewhere.
Five ways to look at the same week
The view switcher has Day, Week, Month, Agenda and Year. Week is the working view. Month shows the events as colored chips for planning further out. Agenda lists everything from today onward, day by day, with times and locations, which is the quickest way to see what's coming without reading a grid.
Opening an event shows the full editor: start and end with time zone, calendar, location, travel time, a meeting link, attendees, repeat (none, daily, weekly, monthly or yearly), reminders, description, visibility and how the event shows you (busy or free). Reminders can be stacked, for example a popup 30 minutes before and another one a day before.
Two more tools sit in the header. Booking links let other people pick a free slot from a link you share, and the booking lands on your calendar. Polls let a group vote on time slots when you need to find a time that works for everyone.
Todos: Today, Upcoming, Overdue
The Todos screen sorts tasks into All, Today, Upcoming, Overdue and Completed, with your own lists (here Launch, Marketing and Docs) underneath. The same tasks can be shown as a List, a Board or a Calendar.
The add field takes shorthand as you type: #tag for a tag and !high for priority, so "Send the launch recap friday #launch !high" carries its tag and priority in one line. Press ⌘↵ instead of Enter and the line is parsed with AI using your model key, so "friday" becomes a due date. Without a key, it's added as plain text.
Clicking a task opens its details: status, priority, due date and time, tags, notes and subtasks that you tick off one by one. Mark done closes it.
The Board view puts the same tasks in To do, In progress and Done columns, for a quick look at where things stand.
Use case: a launch week
Sammy's team ships on Saturday. On Monday morning Sammy types "Launch readiness review Wednesday 10am" into the calendar's quick-add bar, adds Dari as an attendee in the event editor, and sets a reminder for 30 minutes before. The daily standup is a repeating event on the shared Launch calendar, and Sammy's deep-work blocks sit on a private Focus time calendar that the team can't see.
The tasks from the review go into Todos with tags and priorities typed inline. On Wednesday, Today shows what's due, Overdue catches anything that slipped, and the Board view shows the team where things stand. When a partner wants a call, Sammy sends a booking link instead of trading emails about times.
Questions people ask first
Do I need an AI model for quick-add?
No. Calendar quick-add falls back to a built-in parser that doesn't use a model. With your own model key in the desktop app, parsing is better at relative dates, durations and attendees. In Todos, ⌘↵ uses your model key, and without one the task is added as plain text.
Can I share a calendar with my team?
Yes. Each calendar is Private or Workspace. Workspace calendars are visible to your workspace, and private ones stay yours.
Can people book time with me?
Yes. Create a booking link, share it, and people pick a slot; the booking lands on your calendar. Polls collect votes on time slots from a group.
Is it free?
osFoundry is free to use on your own device. Work that runs on osFoundry's servers uses credits.
The desktop app is free to download at osfoundry.io/download.
