We’re excited to share something new in Calendrz that’s been quietly in the works for a while — the Smart Scheduler. It’s a natural-language agent that reads your calendars, figures out when you’re actually free, and turns a sentence like “find a 30-minute slot with Alice tomorrow afternoon” into a concrete proposed time — ready for you to confirm with a single word.
This post walks through how it works, who can use it today, and how it fits alongside the Calendrz MCP server that many of you already use from Claude.ai and Claude Desktop.
What the Smart Scheduler actually does
Calendrz has always been about protecting your availability across every calendar you’re connected to. The Smart Scheduler takes the next step: instead of you hunting through multiple calendars to decide when to meet, you describe the meeting in plain English and let Calendrz propose the time.
It understands your connected accounts, respects your working hours, reads attendee availability when it can, and writes the event back to the right calendar once you say go. Under the hood it’s powered by Claude Haiku 4.5 and has direct, audited access to the same calendar tools you already trust.
How to use it
Once the Smart Scheduler is enabled on your profile, just head to:
You’ll land in a simple chat interface. Type what you want, in your own words:
- “Book a 30-minute intro with alice@example.com next week, mornings preferred.”
- “Find me a lunch slot in San Diego next Tuesday.”
- “Schedule a 1-hour deep work block on Friday — anywhere I’m free after 2pm.”
- “Set up standup with the team on Monday morning.”
The Smart Scheduler replies with a proposed time and the full event details, then waits for your confirmation. Say “yes”, “go”, or “proceed” — and it writes the event to your calendar. Want it earlier? Different attendees? Add a video link? Just tell it, and it revises.
Conversations keep their context, so you can refine across multiple turns without starting over.
Which plans include it
The Smart Scheduler is available on Basic, Plus, Pro, and Ultimate plans. It’s an opt-in feature on your profile — once enabled, you’ll see the /scheduler entry become live for your account. If you’re on a paid plan and don’t see it yet, check the preview status below.
A few use cases we love
Cross-calendar meeting scheduling
You’ve got a work calendar, a personal calendar, and maybe a side-project one. Ask the Smart Scheduler to find time with someone and it considers all of them — no more booking over a kid’s school pickup you forgot was on your personal calendar.
Faster one-on-ones
“Schedule a 25-min 1:1 with Sarah every other Thursday.” One sentence, done — the agent proposes, you confirm, the recurring event lands on the right calendar.
Travel-friendly scheduling
Describe the location (“lunch in San Diego next week”) and the agent respects it when proposing times — no more accidentally booking a video call while you’re on a plane.
Reclaiming focus time
“Block two 90-minute focus sessions this week before 11am.” The Smart Scheduler finds the quiet spots and protects them with events that then mirror across all your connected calendars automatically.
Smart Scheduler vs. the Calendrz MCP
A lot of our users already reach Calendrz through our MCP server — the one you connect to from Claude.ai, Claude Desktop, or any other MCP-compatible client. So what’s the difference?
- The Calendrz MCP gives your external AI assistant a set of low-level tools — list calendars, find free slots, create an event, add attendees, etc. Your assistant decides how to combine them. The MCP also exposes
smart_scheduler_invoke, which lets it call the Smart Scheduler as a single one-shot request. - The Smart Scheduler inside Calendrz is a purpose-built agent with its own UI, multi-turn memory, and a scheduling-specific system prompt. It’s tuned end-to-end for the one job of booking meetings well — no general-purpose context to navigate, no tool orchestration to worry about, and every run is recorded in an audit log on your profile.
Put differently: the MCP is the toolbox — flexible, composable, and assistant-agnostic. The Smart Scheduler is the finished tool — focused, conversational, and built into Calendrz itself. Many of our power users use both, and that’s exactly the design intent.
Preview access and what’s next
The Smart Scheduler is currently in preview mode and enabled for a small group of hand-picked users while we collect feedback and tighten the experience. If you’re in the preview group, you’ll already see /scheduler active on your account.
We’ll be rolling it out more broadly across all paid plans in the coming weeks. If you’d like early access, drop us a note — we’re prioritising users who live across multiple calendars and can stress-test the edges.
As always, your calendars stay yours. The Smart Scheduler only ever writes events you’ve explicitly confirmed, and every run is logged so you can see exactly what happened and when.
More soon — and thank you to everyone in the preview who’s been helping us shape this.
