AI Scheduling Assistant: What It Is, How It Works (2026)
Setting up one call with three people at another company can take nine emails and two days. An AI scheduling assistant takes that thread off your hands: you CC it, and the next thing you see is the invite.
How well that holds up depends on which calendars the assistant can see and who it will email.
The quick answer: An AI scheduling assistant is an AI you CC on an email thread (or text) that finds a time, books it and sends the invite. The label also gets used for apps that plan your own calendar and for booking links with AI added. Carly is the pick for most people: CC it on any thread and it checks all of your Google and Microsoft calendars at once, proposes times, books the meeting, sends the invite and follows up, with free booking pages and group polls on top. Free Zapier-style workflows; AI agents from $35/month.

What an AI scheduling assistant is
An AI scheduling assistant does the back-and-forth of setting up a meeting: it reads the request, checks your availability, offers times, handles replies, books the slot and sends the invite. It is not Outlook’s Scheduling Assistant, the free/busy grid inside an Outlook invite. The name covers three kinds of product.
1. Assistants you CC on the thread
You add it to an email the way you’d loop in a human assistant, and it replies to the other people until the invite goes out. This is what most people mean by the term, and it saves the most time with people outside your company. Examples: Carly, Howie, Calendly’s Callie, Clara, SkipUp, Blockit and Skej. Howie vs Clara compares two of them.
2. Auto-schedulers that plan your own calendar
Motion and Reclaim place your tasks, habits and focus time into open slots and move them when a meeting lands. They don’t email anyone. Clockwise shut down on March 27, 2026. Motion vs Reclaim compares the two survivors.
3. Booking links with AI features
Calendly, Cal.com and Acuity give people a page to pick a time. The AI sits at the edges: Calendly sells Callie on its Plus plans, Cal.com sells Cal.ai phone agents, and Acuity’s Premium plan adds an AI Booking Assistant chatbot. The link still asks the other person to do the picking, and some (executives, big clients) won’t. Carly’s booking pages cover this kind for free.
How a CC’d scheduling thread works
Josh Whitaker runs a four-person data consultancy in Chicago. On Monday, Emily Carter, a director at Databricks in San Francisco, asks for 45 minutes next week with her VP, Michael Hayes, and Claire Donovan from procurement to scope phase two. Here’s the thread on Carly:
- Josh replies and CCs Carly. “Adding Carly to find us a time. 45 minutes, video.” That’s the whole instruction.
- Carly reads the thread. Three people at Databricks, 45 minutes, Emily on Pacific time and Josh on Central.
- It checks every calendar Josh has, at once. His Google Workspace calendar, the Microsoft 365 calendar from a client he’s embedded with, and his personal Gmail calendar with Thursday’s dentist appointment. Busy on any of them means busy.
- It proposes times in Emily’s time zone. Three options in Pacific time, all inside Josh’s working hours.
- It handles the reply. Emily writes back: “Michael’s out Wednesday, and Claire can only do mornings.” Carly drops Wednesday and offers Tuesday at 9:00am PT. When a thread has too many people to sort out by email, Carly sends a group poll instead.
- It follows up when someone goes quiet. Josh asked Carly to nudge after two days, so when Claire hasn’t answered, she gets a short reminder on the thread.
- It books and sends the invite. The event lands on Josh’s work calendar with all four attendees and his default Zoom, Meet or Teams link, and the thread gets a one-line confirmation.
- It does the work the meeting creates. Carly logs the call on the Databricks deal in HubSpot and opens a prep task in Asana. A workflow can do the same for every booking.
Nobody at Databricks installs anything or clicks a link. Running late on Tuesday, Josh texts Carly “ten minutes behind, let them know” and it emails the attendees.
What an AI scheduling assistant costs
The billing unit shapes the bill as much as the headline number:
- Per seat. Calendly’s Callie needs Standard Plus at $18 a seat per month billed yearly, or $24 monthly (Teams Plus is $24 or $32). Skej Pro is $15 per user per month billed annually. Reclaim Starter is $10 a seat billed yearly or $12 monthly.
- Per meeting bundle. Clara Standard is $80 a month for 30 meetings, about $2.67 each. SkipUp Pro is $49 a month for 30 meetings shared across a workspace. Blockit Lite is $83 a month billed yearly ($999 up front) or $145 monthly, for 40 meetings a month.
- Credits. Howie’s Team plan starts at $25 a month for a shared credit pool, with $25 in free credits to start. It doesn’t publish what a meeting costs in credits.
- Auto-schedulers. Motion has no free plan: one person pays $29 a month billed yearly or $49 monthly, and teams pay $19 a seat billed yearly. Reclaim’s Lite plan is free.
- Booking links. Calendly and Cal.com have free plans (Calendly’s covers one event type and one calendar connection). Acuity starts at $16 a month billed yearly ($20 monthly), and its AI Booking Assistant comes with Premium at $49 yearly or $61 monthly.
Carly: Free Zapier-style workflows; AI agents from $35/month. Booking pages and group polls cost nothing.
What to look for in an AI scheduling assistant
- Google and Microsoft at once. Plenty of people have a Microsoft 365 work calendar, a personal Gmail calendar and a client’s calendar on top. An assistant that sees one books over the others. Howie works on Gmail and Google Calendar, and Callie listens on a single mailbox. Carly works across all of your Google and Microsoft accounts at once (more on multiple calendars).
- Groups. Check what happens with five people across three companies. Clara, Howie and Blockit take group threads, Callie is built for one-on-one, and Carly adds free polls.
- Time zones. Times should arrive in the other person’s zone.
- Whose name is on the email. Most assistants reply under their own name, and changing it often costs extra: $20 a month for Howie at your domain, a $199-a-month add-on for SkipUp’s custom name and address, Enterprise for Blockit’s custom domain. Carly’s agents each have their own email address, and teams can send from their own domain (book a call).
- Follow-ups. Threads die when one person goes quiet. Howie and SkipUp chase by default. On Carly, you set the rule once.
- Privacy. Sign in through Google or Microsoft rather than handing over a password, and ask whether a human reads your email and whether the vendor trains on your data. Clara says no person reads your email. Blockit’s written no-training guarantee is an Enterprise feature.
AI scheduling assistants you CC, Carly first
Our best AI calendar assistant roundup covers the wider calendar category.
1. Carly
Carly is an AI assistant that works over email, the web app and text. Scheduling is where most people start, and Carly keeps going after the invite lands.
- CC it on any thread. Carly reads the thread, proposes times, books, sends the invite and handles reschedules.
- Every calendar. It works across all of your Google and Microsoft accounts at once, shared mailboxes included, so a request in your client Outlook mailbox gets the same treatment as one in Gmail.
- Groups. Group polls find a time across a crowd, free.
- Booking pages. Free booking pages check all your calendars, show guests their own time zone and add a Meet, Teams or Zoom link. Team pages too.
- Text Carly. “Move my 3pm to tomorrow and tell them” works by text as well as email.
- A scheduling address. Give recruiting or client intake its own inbox with an Email Agent that people write to directly.
- The work around the meeting. Carly connects to thousands of apps, HubSpot, Salesforce, Zoom, Slack and Asana among them, and acts on notes from Fathom, Fireflies or Granola to send the follow-up and book the next call.
- From ChatGPT or Claude. Add the Carly plugin in ChatGPT or the Carly connector in Claude and schedule from that chat.
Best for: Anyone who schedules across more than one calendar or more than two people, and wants the CRM update and follow-up done too. Pricing: Free Zapier-style workflows; AI agents from $35/month. Booking pages and polls free. Setup: Get started, then CC Carly on your next scheduling thread.
2. Howie
Howie schedules by email, iMessage and SMS, follows up when people go quiet, and can use an address at your domain for $20 a month extra. Team starts at $25 a month in shared credits. Pick it if you live in Gmail and Google Calendar and scheduling is the whole job.
3. Calendly Callie
You add callie@calendly.com to a thread and it replies within a minute with times.
One mailbox, one-to-one, English, and the plans that carry Plus. That is the shape of Callie: the address you sign into Calendly with, no shared mailboxes, To or Cc but never Bcc, and scheduling links still doing the work whenever more than two people are involved. Its replies offer three days of availability, five slots a day. Carly holds all of your mailboxes, answers from shared ones, and books across a group.
Pick it if you already pay for Calendly and most meetings are one-on-one from your login address. Our Calendly Callie guide has the detail.
4. Clara
Clara helped start this category in 2014, works with Google and Outlook, and handles group threads. Standard is $80 a month for 30 meetings after a 14-day trial. Pick it for a dedicated scheduler on Outlook.
5. SkipUp
SkipUp is built around follow-ups on stalled threads, for sales, customer success and recruiting teams. Free for 10 meetings, then $49 a month for 30.
6. Blockit
Blockit works over email and Slack with Google and Microsoft calendars, and when both sides use Blockit the agents book directly. Free covers 15 meetings a month; Lite is $83 a month billed yearly.
7. Skej
Skej is the low-cost option at $15 per user per month billed annually, with Google and Microsoft calendars and a free booking link.

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."
