Calendly Callie vs Clara (2026): Which AI Scheduler?
Clara has worked one way since 2014: copy an assistant on the email, and it trades times with the other person until a meeting lands on your calendar. Calendly’s Callie, in beta since August 19, 2026, brings the same move to the biggest name in booking links. Same move, very different reach.
The quick answer: Pick Callie if you already pay for Calendly and most of your meetings are one-on-one calls requested at your Calendly login address. It costs a fraction of Clara and comes with Calendly’s Notetaker. Pick Clara if you schedule groups over email, get requests at more than one address, or run on Outlook and want a dedicated scheduler that chases people on a timer, at $80 a month for 30 meetings. If requests also land in a shared inbox, or you want the work after the call done too, Carly is the third option: CC it from any of your Google and Microsoft mailboxes and it books groups, takes requests by text, and sends the follow-up. Free Zapier-style workflows; AI agents from $35/month.

Setup: what each one needs before the first thread
Callie. A Standard Plus or Teams Plus seat, an English-language account, a one-on-one event type, and default event type settings for Callie to fall back on when you don’t specify. Our Calendly Callie guide breaks down the plans.
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.
Clara. Sign up without a card, connect your Google or Microsoft calendars, and paint your week into Preferred, Flexible and Do Not Schedule blocks. Then set buffers, how often Clara follows up, and whether coworkers get booked straight onto their calendars. Booking Types let a phrase like “recruiting call” swap in a different set of rules.
Carly. Get started, connect every Google and Microsoft account you use, and CC Carly on your next scheduling thread.
How one thread goes on each
Claire Donovan is an employment lawyer in Chicago. Her firm runs on Microsoft 365, and her firm Outlook address is her Calendly login. Two days a week she is of counsel at a second firm on Google Workspace, and some clients write to her there. On Monday, Michael Grant, head of HR at a Denver freight company, emails her Google address: “Could we get 45 minutes next week with you and whoever handles wage-and-hour claims?” That’s Josh Bennett, an associate at her main firm.
With Callie
Callie answers only at Claire’s Outlook login, so the conversation has to move there first. Then it’s a three-person call with two hosts on Claire’s side, which Calendly’s own help center assigns to a scheduling link. Claire sends Michael a link to a team event instead.
Had it been Claire and Michael alone, from her Outlook address, Callie is quick. Within a minute it sends Michael up to three days of times, five a day, plus a link to see more, with a green dot on mutual free times if he uses Calendly too. He replies “Thursday at 2” and the invite goes out.
With Clara
Claire has both calendars connected and both addresses on her Clara profile, so she answers from Google: “Clara, please find 45 minutes next week for Michael, Josh and me, on Zoom.” Clara reads both of her calendars. Josh is the catch. On Microsoft, Clara can see a colleague’s calendar only if that colleague also uses Clara, so unless Josh has a seat, Claire’s internal-meeting setting has Clara email him for his open windows first.
From there Clara offers Michael times in Mountain time if the thread shows where he is, nudges him on Claire’s schedule when he goes quiet, and sends the invite once all three agree, from the Google address Michael wrote to if Claire turned that setting on. The Zoom link is the personal one she saved, since Clara’s help center lists automatic Zoom links as still in development.
With Carly
Claire answers from her Google address and CCs Carly: “Adding Carly to set up 45 minutes with Josh and me next week.”
- Carly reads every calendar Claire has connected: the firm’s Microsoft 365, the Google Workspace one and her personal Gmail. Busy on any of them blocks the slot.
- It offers times in Michael’s Mountain time zone and keeps Josh on the same thread.
- It chases the quiet ones. Claire’s rule is a nudge after two days, and that’s what Michael gets.
- It books with her default Teams or Zoom link.
- It handles what the call creates. Claire takes notes in Granola. Carly reads them, drafts the email to Michael with the agreed next steps and the engagement letter, logs the matter in Clio, and puts the follow-up review on all three calendars. A workflow can run those steps after every new-client consult.
Requests that land in the firm’s shared intake@ mailbox get the same treatment, with no forwarding first. Stuck in a deposition, Claire texts Carly “push Michael 30 minutes and tell him,” and it emails the attendees.
Group meetings
Callie handles one guest at a time. Calendly’s guidance for multiple hosts, group scheduling or team coordination is a booking link, and if two people on a thread each add Callie, only the first one responds.
Clara was built for the crowded thread. Copy it with up to seven participants, say who’s optional, and it contacts everyone, tracks responses, follows up and confirms once a time works. For coworkers it can Autobook straight onto their calendars, ask for their general windows, or treat them like outside guests. The limits are one meeting per thread and, on Microsoft, visibility only into colleagues who also use Clara.
Carly works group threads the same way and adds free group polls when a crowd needs to vote. For people who’d rather click a slot, Carly’s booking pages are free, team pages included. Our Callie alternatives roundup covers more group options.
Outlook and Microsoft 365
Callie works in Outlook when Outlook is your Calendly login, and Calendly connects Outlook/Office 365 and Exchange calendars. It won’t answer at a second Outlook address or a shared mailbox.
Clara treats Outlook and Exchange as first-class and pitches itself to law, accounting and financial advisory firms on Microsoft for that reason. It adds a Teams link by default when your domain is hosted by Microsoft. Its FAQ calls Clara the only assistant with native Outlook support; Callie works from Outlook too, though only from the one login address. Howie vs Clara compares it with a Google-first rival.
Carly works across Outlook and Gmail at the same time, shared Microsoft 365 mailboxes included.
Price: per seat versus per meeting
Callie is billed per seat, and the seat also includes Calendly Notetaker. Standard Plus is $18 a month billed yearly or $24 billed monthly; Teams Plus is $24 or $32. Calendly publishes no meeting limit for Callie. Free, Standard and Teams don’t include it, and Enterprise customers ask Calendly for access.
Clara is billed by volume. Standard is $80 a month for 30 meetings, about $2.67 a meeting, and the pricing page shows no annual option. The free plan covers 5 meetings in 14 days with no card; past that, Clara stops taking new meetings until you upgrade. Enterprise, with no meeting cap, a custom domain and an admin dashboard, is priced on a call.
For one person, that’s $216 a year for Callie billed yearly against $960 a year for Clara Standard. Clara’s premium buys group threads, timed follow-ups and several addresses. If you need none of those and already live in Calendly, Callie is the cheaper way to get CC scheduling.
Carly: free Zapier-style workflows; AI agents from $35/month, with booking pages and group polls free.
Who reads your email, and what trains on it
Callie. Calendly says Callie reads the thread for scheduling details, ignores the rest, and never uses your data to train AI models. Calendly staff and the service providers that power Callie can access it, and the data is stored in the US on Google Cloud and AWS. Calendly also says it isn’t HIPAA or GLBA compliant, which matters to health and financial practices.
Clara. “No human at Clara reads your emails. Not a reviewer, not a contractor,” its homepage says, and it says it never trains models on your data. That reverses how Clara started, routing tricky messages to human assistants, as our Clara Labs history covers. Clara reads only threads it’s copied on, writes from its own address rather than your mailbox, and sends invites from your calendar.
Carly. Carly connects through Google’s and Microsoft’s own sign-in, never sees your password, and states that your data, Google and Microsoft data included, is never used to train AI models.
Carly: one assistant for every inbox and the work after the call
Callie and Clara both stop once the invite goes out. Carly carries on.
- Every mailbox you connect. A request at intake@, sales@ or a second firm’s address gets the same treatment as one in your main inbox.
- Groups without a link. Group threads by email, free group polls for a crowd, and free booking pages for people who’d rather pick.
- A scheduling address of its own. Set up an Email Agent for client intake or recruiting, with its own name and address that people write to directly, on your own domain if you like (assistant@yourfirm.com).
- Scheduling by text. “Move my 3pm to tomorrow and let them know” works over SMS.
- The recorder you already use. Carly acts on notes from Fathom, Fireflies or Granola.
- The rest of the stack. Carly connects to thousands of apps, such as HubSpot, Salesforce, Clio, Slack and Zoom, so booking the consult, logging it and opening the task is one instruction.

FAQ
Is Callie better than Clara?
For one-on-one calls from your Calendly login address, Callie is far cheaper if you already pay for Calendly. Clara does more of the scheduling job: groups, timed follow-ups and several addresses. For shared inboxes and the follow-up work too, Carly covers it.
Is Clara still around, and does a human read its emails?
Yes. Clara is operating in 2026 under Clara AI, Inc. and taking signups. Its site says no human reads your emails, not a reviewer and not a contractor, which reverses the human-assisted model it ran in its early years.
Which is cheaper, Callie or Clara?
Callie, for most people. It comes with Standard Plus at $18 a seat per month billed yearly ($24 monthly), and Calendly publishes no meeting limit for it. Clara Standard is $80 a month for 30 meetings, and Enterprise is priced on a call. Carly: free Zapier-style workflows; AI agents from $35/month.
Do Callie and Clara work with Outlook?
Both do. Callie works from Outlook only if it’s your Calendly login address. Clara supports Outlook and Exchange natively across several of your addresses. Carly works across all of your Outlook and Gmail accounts at once, shared mailboxes included.
Can Callie schedule group meetings like Clara?
Not today. Calendly says Callie works best for one-on-one meetings and that scheduling links remain the tool for groups and multiple hosts. Clara handles group threads with up to seven participants per request. Carly handles group threads by email and adds free group polls.
What’s the best Clara Labs alternative?
It depends on why you’re leaving. If price is the reason, your meetings are one-on-one and you’re on Calendly, Callie is the cheapest way to keep CC scheduling. If you want scheduling plus the rest of your inbox, Carly works the same CC way across all of your mailboxes and goes on to the follow-up email, the CRM and your workflows. Our Clara alternatives list has more options.

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."
