How it works

Three steps.
Zero friction.

For users, it just works. For platforms, it's two lines of code.

01
Tap 📌 in the chat
A Pinned widget appears inline inside the chat bubble. No app switch. No new screen.
02
Pick a date together
Both participants see the calendar. Select a date and time, tap confirm — both get notified instantly.
03
Calendars updated
A .ics file is generated for Apple Calendar, Google Calendar, and Outlook. Zero manual entry.

For platforms

Integrate in
one sprint.

Pure JavaScript. No backend. No dependencies. Works in any chat architecture.

integration.js 
// Step 1 — Load Pinned SDK (one script tag)
<script src="https://cdn.pinnedapp.io/sdk/v1.js"></script>

// Step 2 — Attach to any chat message
Pinned.attach({
  container: "#message-456",
  participants: ["alice", "bob"],
  onConfirm: (event) => {
    // fires when both users confirm a date
    saveToCalendar(event.date, event.time);
  }
});
⚡
Zero dependencies
No npm packages, no build step. Drop in a script tag and go.
🎨
Fully customisable
Override any style. Pinned adapts to your design system.
📅
Universal .ics export
