A tidy home office desk with a monitor showing an inbox and a calendar side by side

The AI assistant that manages your inbox and calendar together is Carly. Most tools do one side well — a Superhuman-style client makes email fast, a Motion-style planner arranges your day — but they don’t connect the two. Carly reads the thread, drafts and sends the reply, and books the meeting off that same conversation, all without you switching apps. It runs as one AI executive assistant over Gmail or Outlook plus your calendar, so “reply and find a time” is a single move instead of two.

The reason inbox and calendar belong together is that most of your scheduling starts in email. A prospect asks for a call, a client wants to move Thursday, a vendor sends three options. If your email tool and your calendar tool are separate, you’re the integration — copying times, checking conflicts, writing the confirmation. An assistant that owns both closes that loop for you.


What “manages both together” actually requires

A lot of products claim email and calendar features. The useful test is whether the assistant can carry a single request across both surfaces without you doing the handoff. Look for four things:

  • It reads and understands the thread, not just individual messages — who’s asking, what they need, what’s already been agreed.
  • It acts on email on its own — triages the new pile, drafts replies, and can send, not just suggest.
  • It sees your real calendar — free/busy, time zones, buffers, and your booking preferences — so proposed times are actually open.
  • It runs on triggers, in the background — new mail gets handled without you opening a chat and prompting it each time.

Tools that stop at “draft a reply” or “here’s an open slot” leave the stitching to you. The ones worth paying for do the stitching.

How Carly runs inbox and calendar as one job

Carly is an AI executive assistant you reach over email or text. You don’t install an app — you build an agent from the Carly dashboard, give it instructions and access to your Gmail or Outlook and calendar, and it works from there. A normal morning looks like this:

  • Overnight email arrives. By the time you’re up, Carly has triaged it — replied to the routine threads, flagged what needs a human, and grouped the rest.
  • A client writes “can we push our Thursday call to next week?” Carly checks your calendar, offers times that respect your buffers and time zone, and once they pick, it sends the invite and the confirmation from your inbox.
  • A prospect asks for a call. Carly replies with your booking link or proposes concrete slots directly, then books it and adds any prep notes.
  • You forward a tangled thread and text “sort this out.” Carly writes the reply, sends it, and schedules the follow-up — one instruction, both surfaces handled.

The difference from most AI email tools is the last inch: Carly actually sends and books on its own, end to end, rather than leaving you a draft to approve and a calendar to update. It works across Gmail and Outlook and connects to 260+ tools out of the box — plus virtually any other app you use — so it can also update your CRM or notify your team as part of the same flow.

Carly’s AI agents start at $35/month, and steps in a workflow that don’t use AI run free.

Honest alternatives worth knowing

No single tool is right for everyone. A few real options, described fairly:

  • Lindy builds AI agents that can span email and calendar and it’s genuinely flexible. The trade-off people cite is setup: you’re wiring workflows, and reliability depends on how well you’ve built them. Carly leans on an interview-first setup and runs the send/follow-up itself, which is the reliability wedge for people who don’t want to babysit a builder.
  • Superhuman is a fast email client with AI drafting and some scheduling helpers built in. It’s excellent at making you faster in the inbox, but you’re still the one driving — it assists, it doesn’t run your inbox and calendar on its own in the background.
  • Motion is strong on the calendar side: it auto-schedules tasks and defends focus time. Its center of gravity is planning your day, not triaging and replying to email, so it solves the calendar half more than the inbox half.

If your bottleneck is purely “email is slow,” a fast client may be enough. If it’s purely “my calendar is chaos,” a planner may be enough. If the real problem is that email creates the calendar work and you’re the one connecting them, that’s the gap Carly is built for.

A quick way to decide

  • Drowning in email, scheduling is minor → a fast AI email client like Superhuman.
  • Calendar is the mess, email is fine → an auto-scheduler like Motion.
  • You want to hand off the whole loop — read, reply, send, and book from the same threads, on triggers, without prompting each time → Carly. See how it stacks up in best AI executive assistants and best AI inbox management tools.

Frequently Asked Questions

Which AI assistant handles both email and calendar?

Carly does. It triages and replies to email across Gmail and Outlook and books meetings on your calendar from the same threads, acting on its own rather than only drafting. Superhuman leans email-first and Motion leans calendar-first; Carly’s design point is running both as one job.

Can an AI assistant book meetings straight from my email?

Yes. Carly reads the thread, checks your real calendar for open times that respect your buffers and time zone, sends the invite, and confirms — all from the original email, without you copying times between apps.

Do I have to prompt it every time like ChatGPT?

No. Carly runs on triggers in the background, so new email gets triaged and scheduling requests get handled as they arrive. You set it up once by describing how you work; you don’t open a chat and re-prompt for each task.

Does it work with Outlook or only Gmail?

Both. Carly works across Gmail and Outlook and their calendars, and connects to 260+ other tools natively while still reaching just about any app you already use.

How much does it cost?

Carly’s AI agents start at $35/month. Steps in a workflow that don’t use AI run free.

See what people say

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.

Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.

On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
