Blockit vs Skej: Which AI Scheduler in 2026?
People compare these two because both are AI scheduling assistants that book meetings for you, but they take almost opposite routes to it. Blockit is an autonomous AI scheduling agent that connects to your Google or Outlook calendar and negotiates times directly, and when the other person also runs Blockit their agents settle on a slot calendar-to-calendar with no booking link and no email thread. Skej is a persona-based conversational assistant you CC on an email or message in Slack, Teams, SMS, or WhatsApp, and it handles the back-and-forth with your guests the way a human EA would. The core distinction is the mechanism: Blockit bets on an agent network that talks calendar-to-calendar; Skej meets people in whatever channel the conversation already lives in. Name which of those actually fits how your meetings get booked and the choice gets easy. If you’re still weighing the field, our best AI scheduling assistants roundup has the wider view.
The One-Sentence Answer
Use Blockit if you want an autonomous agent that negotiates calendar-to-calendar, especially where colleagues also use it; use Skej if you want a named assistant you can CC or text across email, Slack, Teams, SMS, and WhatsApp.

| Signature move | Agent-to-agent negotiation when both sides run Blockit | Books over the channel where the conversation lives |
| Channels | Email CC and Slack | Email, Slack, Teams, SMS/iMessage, WhatsApp |

| Best fit | Agent-dense teams that want zero-touch scheduling | People who book across many channels on a budget |
When to Use Blockit
- You work somewhere colleagues and counterparties already run Blockit, so the agent-to-agent negotiation actually fires
- You want scheduling with no booking link and, ideally, no email thread at all
- You live in back-to-back meetings and the premium price is defensible for the time saved
- You’re on Google Calendar or Outlook and mostly schedule with other calendar-heavy professionals
- Your problem is the negotiation itself, and you want an agent to own it end to end
Blockit’s bet is a network: when both parties’ agents can talk, they settle a time directly and the human never touches it. It launched in early 2026 with a $5M seed led by Sequoia and backing from Jeff Weiner, and reports put it at around $1,000/year for an individual and $5,000/year for a team after the 30-day trial. When the other side isn’t on Blockit, it falls back to negotiating with humans over email or Slack, like other CC-based schedulers.
When to Use Skej
- You book meetings across several channels and want one assistant in all of them
- You’d rather CC or text a named assistant than route everyone through a booking link
- You want to start free or cheap and add the email assistant when you’re ready
- You like the idea of picking an assistant persona (or building a custom one) to match your tone
- You schedule with people who won’t be running any scheduling agent themselves
Skej’s bet is ubiquity of channel: it meets meetings where they already happen, whether that’s a Gmail thread, a Slack DM, or an SMS. It offers 13 named assistants plus a custom option, works in 80+ languages, and can even coordinate alongside a human EA. Its Free Forever tier covers a booking link and a short assistant trial; the paid email assistant starts around $15/month on the Pro plan, with custom assistants and unsupervised mode on Premium around $23/month. Note that texting, WhatsApp, Slack, and Teams sit on higher or contact-sales tiers rather than the entry plans, so confirm your channel is included before you commit.
The Question That Actually Decides It
It comes down to one thing: is the person on the other side of the meeting likely to be running the same tool? Blockit’s whole advantage — calendar-to-calendar negotiation with no thread — only exists when both agents can talk to each other, which is why it compounds at agent-dense firms and reads as an expensive email scheduler everywhere else. Skej makes the opposite assumption: the other person is a normal human reachable on email, Slack, or their phone, so it optimizes for showing up in every channel rather than for a network. Buy Blockit expecting universal zero-touch scheduling and you’ll be disappointed the moment you invite an outsider; buy Skej expecting fully silent agent negotiation and you’ll notice it still sends messages.
There’s also a ceiling both share. Blockit and Skej both stop at the booked meeting. Neither one writes and sends the follow-up email afterward, updates the record in your CRM, or runs the next step of the workflow the meeting was for. They arrange the time; the work around the meeting still comes back to you. If you’d rather delegate that outcome than just get the invite on the calendar, that’s a different kind of tool: Carly is an AI assistant whose agents each have their own email address, so they reply to people, book meetings, send follow-ups, and update your CRM on their own, working with Gmail or Outlook across 200+ integrations, and you set it up by describing what you want in plain English.

FAQ
Does Blockit work if the other person doesn’t use it? Yes, but without the headline benefit. Blockit’s agent-to-agent negotiation only happens when both sides run it. When the counterparty isn’t on Blockit, it falls back to scheduling with them over email or Slack, similar to how Skej and other CC-based assistants work.
Which one has more communication channels? Skej. It operates across email, Slack, Microsoft Teams, SMS/iMessage, and WhatsApp, while Blockit works through email CC and Slack. If reaching people by text or WhatsApp matters, check Skej’s tier gating, since those channels sit above its entry plans.
Is Blockit worth roughly $1,000 a year over Skej’s cheaper plans? It depends entirely on whether your network runs Blockit. At an agent-dense company where meetings settle calendar-to-calendar, the time saved can justify it. If most of your meetings are with outside people who won’t install anything, you’re paying a premium for a fallback that costs far less elsewhere.
What if I want the meeting’s follow-up work done, not just the booking? Neither tool does that; both hand the booked meeting back to you. An AI assistant like Carly is built to act after the invite lands — sending the follow-up, logging it in your CRM, and running the next step across your other tools. Pricing starts at $35/month.

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."
