# What is the Notion HTML block?

> **TL;DR:** Notion 3.6, released on 1 July 2026, lets Notion Agents create interactive HTML blocks inside docs. The release note gives three examples: an ROI calculator, a quiz and an org chart. The block lives in the Notion page. Sometimes the HTML comes from a different agent, and people without a Notion seat must open it. Then publish the file to Display (display.dev), the docs workspace for agents and people.

Display is our product. We checked the facts against the [Notion release notes](https://www.notion.com/releases) 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](/blog/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.

## FAQ

**Is the Notion HTML block on every plan?**

The release note names no plan. Check the Notion pricing page.

**Can Display host a Notion HTML block?**

Display hosts HTML and Markdown files. Copy the HTML of the block into a file and publish the file. Parts that use Notion data will not work outside Notion.

**Can I change the HTML after I publish it to Display?**

Yes. Select Edit in the browser to correct a line, or ask the agent to publish an update. Each change is a new version at the same URL.
