Blockit vs Howie: Which AI Scheduler in 2026?
Blockit is an AI scheduling agent you CC on an email thread or message in Slack; when the person on the other side also runs Blockit, the two agents negotiate a time directly, calendar-to-calendar, with no booking links at all. Howie is an AI scheduling assistant with its own email address and phone number that you CC to run the booking thread with real people, proposing times, replying to the other party, and sending the invite like a delegated secretary. The one distinction that decides most of it: Blockit bets on a network where agents talk to each other, while Howie bets on a secretary that talks to humans. Name which of those two worlds your meetings actually live in and the choice is nearly made. If you’re weighing either against a broader assistant, see Blockit alternatives and Howie alternatives.
The One-Sentence Answer
Use Blockit if the people you schedule with already run scheduling agents and you want frictionless agent-to-agent negotiation; use Howie if you want a cheaper, human-facing secretary that books with anyone over email on Google Calendar.
Side-by-Side Comparison
| Dimension | Blockit | Howie |
|---|---|---|
| What it is | AI scheduling agent / “calendar network” | AI scheduling secretary you CC |
| How a meeting gets booked | CC by email or Slack; agents negotiate directly when both sides run Blockit | CC by email or text; assistant runs the thread with humans |
| Booking links | None by design — agents settle the time | None — Howie replies in the thread |
| Calendars | Unlimited Google and Outlook calendars | Google Calendar only (Outlook on roadmap) |
| Best when | Your counterparts also use Blockit | Your counterparts are ordinary email users |
| Pricing (2026) | $1,000/yr individual, $5,000/yr team; 30-day trial | ~$25/mo standard, ~$95/mo premium |
| Backing | $5M seed (Sequoia, Jeff Weiner) | $6M (Sequoia, Andreessen Horowitz) |

When to Use Blockit
- Many of the people you meet with are at agent-dense companies (Blockit cites use across 200+ companies including a16z, Brex, and Together.ai) and likely to run a scheduling agent too.
- You juggle several Google and Outlook calendars at once and want them all connected without per-account limits.
- You never want to send a booking link and would rather have a time settled agent-to-agent.
- You’re comfortable with a four-figure annual commitment for a polished, enterprise-leaning experience.
When both sides run Blockit, the back-and-forth genuinely disappears; when they don’t, it falls back to a capable but ordinary email scheduler, so the value tracks how much of your network is on it.
When to Use Howie
- You want the assistant experience at consumer pricing rather than a $1,000/year license.
- The people you book with are ordinary email users, not agent operators, so a human-facing secretary matters more than agent-to-agent negotiation.
- You want your assistant to have its own email address and phone number and to feel like a delegated person handling your calendar.
- You live in Google Calendar and don’t need Outlook today.
Howie leans into the “people’s secretary” framing: it negotiates with humans over plain email, applies your rules for buffers, travel time, meeting types, and VIPs, and nudges anyone who goes quiet.
The Network Bet vs the Secretary Bet
The real fork isn’t features, it’s which assumption you’re betting on. Blockit’s edge only fully materializes when the other side also runs Blockit, so you’re betting the scheduling-agent network keeps growing; until it does, you’re paying a premium for a fallback experience Howie delivers for a fraction of the price. Howie makes no network bet at all, which is its strength today and its ceiling tomorrow, since there’s no agent-to-agent shortcut when both parties are power users, and it’s Google-only for now.
There’s a limit both share: they book the meeting and stop. Neither one sends the recap afterward, updates the CRM, drafts the prep doc, or texts you before the call. That surrounding work still lands back on you. If what you actually want is the outcome handled rather than just the slot booked, that’s a different kind of tool. Carly is an AI assistant whose agents each have their own email address: they run the same CC-to-schedule motion, then keep going after the invite lands, replying to people, sending follow-ups, and updating your CRM on their own across Gmail or Outlook and 200+ integrations, set up by describing what you want in plain English. It starts at $35/month.

FAQ
Does Howie support Outlook? Not yet. Howie is Google Calendar only as of 2026, with Outlook described as on the roadmap. Blockit connects unlimited Google and Outlook calendars, so if you’re on Microsoft 365, Blockit is the one of the two that works today.
Do I need the other person to use Blockit for it to work? No, but that’s where its advantage lives. When both sides run Blockit, the agents negotiate the time directly with no email back-and-forth. When the other side doesn’t, Blockit falls back to scheduling with them over email, more like Howie.
Why is Blockit so much more expensive than Howie? Blockit is priced as a premium, enterprise-leaning product at $1,000/year individual and $5,000/year team, while Howie targets individuals at roughly $25/month (premium ~$95/month). You’re partly paying Blockit for the agent-to-agent network and multi-calendar support.
Can either one book by text or handle a phone number? Howie has its own email address and phone number, so you can text it to schedule and it can field calls tied to booking. Blockit works over email and Slack rather than SMS. If a phone-reachable assistant matters, that’s a point for Howie.

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."
