Blockit

Blockit is an AI scheduling agent that books meetings for you when you copy it on an email or Slack thread, aimed at investors, executives and operators whose calendars are full of external meetings. It replaces the human assistant step of trading availability by email, and it is designed to handle messy cases such as group calls across time zones or deciding between a coffee and a video call. Its backers include Sequoia.

What is Blockit used for?

Blockit is used to remove yourself from scheduling threads. You stay in the conversation for the substance, and the agent handles finding and confirming the time.

• Booking meetings after you CC Blockit on an email thread
• Scheduling from Slack threads and DMs as well as email
• Combining availability from several Google and Outlook calendars
• Handling time zones, group meetings and in-person versus Zoom, Google Meet or Microsoft Teams formats
• Asking you for a decision when a request is unclear instead of guessing
• Running with different autonomy levels, from approving every invite to full autopilot

Who Blockit is best for

Blockit suits venture capitalists, founders, executives and sales leaders who book dozens of external meetings a week and value speed and polish. Companies that want a scheduling agent for a leadership team will look at the Enterprise plan for SSO and admin dashboards. Individuals with light schedules can use the free plan, but the paid tiers are priced for heavy users.

Blockit pricing

As of October 2026, Blockit has a free plan with 15 meetings per month, email and Slack agents and instant replies. Lite costs $83 per month billed as $999 per year and raises the limit to 40 meetings per month with a proactive agent. Infinity costs $395 per month billed as $4,740 per year and offers unlimited meetings. Enterprise starts at $20,000 per year and adds SSO, admin dashboards, a custom domain, a dedicated success manager and a SOC 2 Type II report. Blockit says plans begin with a 30-day trial that needs no credit card.

Blockit limitations

• Paid tiers are billed annually, and the top plan is a large commitment for one person
• It needs broad calendar and inbox access, which security teams may want to review
• Guests who dislike automated assistants may prefer a direct link or a human reply
• The free plan's 15 meetings a month will not cover a busy external calendar

Blockit vs alternatives

Reclaim AI is the better pick if you want automatic time blocking for tasks, habits and focus time rather than an agent that emails people. Motion fits people who want an AI calendar tied to project and task planning. Lindy is a general agent builder that can include scheduling alongside other tasks. Fyxer AI is focused on sorting email and drafting replies. Blockit wins when you need an agent that negotiates meetings over email and Slack with very little supervision.

Tips for getting started with Blockit

Connect every calendar you use, including personal ones, so Blockit does not book over private commitments. Start in review mode, where you approve each invite, and move toward autopilot once its choices match yours. Set clear defaults for meeting length, buffers and preferred locations for in-person meetings. Use the 30-day trial to count how many meetings you schedule, which tells you which tier fits.
