Blockit

Blockit

Blockit is an AI scheduling agent that you copy on an email or Slack thread the way you would copy an executive assistant. Blockit reads the thread, proposes times, negotiates with the other side, accounts for time zones and required-versus-optional attendees, and sends a calendar invite with a video link; when plans change it reschedules on its own. For colleagues it reads calendars directly, for outside guests it proposes and follows up, and it stops nudging after a set number of unanswered attempts. Blockit works with Google and Microsoft calendars, Zoom, Meet, Teams, and Slack, and the autonomy level runs from review-every-invite to full autopilot per person or meeting type. As of 2026 the free tier covers a small number of meetings a month, paid tiers add a proactive agent for conflicts and travel, and the company holds SOC 2 Type II.

Production credibility: SOC 2 Type II; January 2026 press including the headline 'Former Sequoia partner's new startup uses AI to negotiate your calendar for you'; on-site testimonials from Jeff Weiner (former LinkedIn CEO), Rich Miner (Android founder), and an Andreessen Horowitz managing partner; site states 2,150 scheduling emails written and 139 hours saved per exec per year.

Key Features

• CC the agent on any email or Slack thread; it handles the whole back-and-forth and sends the invite
• Group scheduling that reads colleagues' calendars directly and proposes to external guests, weighting required and optional attendees
• Saved preferences and memory: meeting templates, in-person days, movable versus fixed events, default locations
• Proactive rescheduling when someone declines, a flight lands late, or a counterparty goes quiet, with a stop after repeated no-replies
• Autonomy dial from review-everything to full autopilot, adjustable per person or meeting type
• Autoblocking: when both parties use Blockit the meeting books in under a second with no emails sent
• Google and Microsoft calendars, Zoom, Meet, Teams, and Slack; multiple calendars kept separate
• Enterprise tier adds SSO, RBAC, admin dashboards, custom domain (blockit@yourfirm.com), and delegate access for EAs

Ideal Use Case

Founders, investors, and executives who take many external meetings and either pay an assistant or lose hours a week to scheduling email. Blockit is the pick over a booking-link tool like Calendly when you do not want to push a link at people and would rather have the negotiation happen inside the existing thread, in your voice, with your rules.

How Blockit differentiates

Booking links push work onto the other party; Blockit does the negotiating itself and knows which decisions are yours, pausing on things like a conflicting board prep instead of moving it. The autonomy dial and per-meeting-type rules mean it can start in review mode and earn full autopilot. Its network effect is real: two Blockit users book against each other instantly with no emails. As of 2026 it is one of the few scheduling agents with SOC 2 Type II and a written enterprise no-training commitment. The honest trade-offs are that the paid tiers are priced like an assistant replacement rather than a SaaS add-on, the free plan caps meetings per month, and outside guests still receive emails from an agent, which some contacts may find impersonal.

FAQ

Q: Is there a free version of Blockit? A: Yes. A free-forever tier includes a limited number of meetings per month with the email and Slack agents, and every paid plan starts with a 30-day trial with no credit card.

Q: Does Blockit work with Outlook and Teams? A: Yes. It supports Google and Microsoft calendars, Zoom, Meet, and Teams links, and Slack, and can connect several calendars without mixing their data.

Q: How does Blockit compare to Calendly or Clockwise? A: Calendly hands the other person a booking page; Clockwise optimises your own calendar. Blockit negotiates inside the email thread with the counterparty and sends the invite, so nobody visits a link.

Q: Can I approve invites before they go out? A: Yes. You choose an autonomy level from review-everything to full autopilot and can change it per person or per meeting type.

Q: Is Blockit secure enough for a fund or law firm? A: The company holds SOC 2 Type II, encrypts data at rest and in transit, offers granular calendar permissions, and states that it reads only what it needs to schedule and never across calendars. Enterprise plans add SSO, RBAC, custom retention, and an MSA with DPA.

tl;dr

Blockit is an email-and-Slack scheduling agent that negotiates meetings on your behalf and sends the invite, with a real free tier and SOC 2 Type II. Excellent for executives with heavy external calendars; paid plans are priced like an assistant, not an app.
