What Is the Notion HTML Block, and Who Can Open It?

Display is our product. We checked the facts against the Notion release notes on 14 October 2026.

What Notion released

The Notion 3.6 release note ("External Agents, HTML blocks, and more", 1 July 2026) says that Notion Agents can create interactive HTML blocks. The blocks live in the doc, so teammates can use them or change them. The note gives three examples:

• An ROI calculator for a customer.
• A quiz that scores the answers.
• An org chart from a people database.

The note names no plan and no limits for HTML blocks.

What the note does not say

The release note does not say who can open an HTML block outside the Notion workspace. It does not say how a block works on a published Notion page. Check the Notion help center before you depend on either one.

When the HTML comes from a different tool

A Notion Agent creates an HTML block inside Notion. HTML from Cursor, Codex or Claude Code is a file. To share that file with colleagues, tell your agent: "Publish roi-calculator.html to Display for my company."

Colleagues sign in with Google or Microsoft (Pro) or with a one-time password. The agent publishes each update at the same URL. Display has no seat fee for readers. Notion prices by member. Read Notion alternatives for the comparison.

When Notion is the better choice

• The calculator belongs inside a wiki page, next to other content.
• Your team already works in Notion and changes blocks together.
• You need databases and relations next to the HTML.
