An HTML block is a file displayed directly on the Canvas as a visual or interactive piece of content. Ask the agent to make a comparison, chart, diagram, or styled briefing from your sources.

​
Create a block

1

Select source material

Select the files, notes, or records the visual should explain.
2

Describe the result

Ask: “Create an HTML block comparing these three proposals. Show cost, delivery dates, and open questions, with a filter by vendor.”
3

Review the data and controls

Check the visual against its sources. Try each control and ask for changes to the content or layout.
See Build a useful visual for examples and a review process.

​
Interact, edit, or expand

Click a control to interact with the block. Use Edit for supported editable text regions. Editing requires write access; readers can use local interactive controls. Select the block and press Enter, or choose Expand, for a larger view. Press Escape to leave an interaction or return to the Canvas. HTML content can also use document presentation. Open the file to read or revise longer content in the document pane.

​
What is saved

The block’s file content and supported text edits are saved. Interactive controls such as filters, tabs, or calculators operate locally. Their temporary state isn’t shared with other readers or guaranteed to survive reloads.
HTML blocks have no network access, cookies, or persistent browser storage. They don’t independently read Connectors, send messages, or maintain a shared database.
For durable records, ask the agent to keep the source data in files or Canvas objects and update the visual from that data. For recurring refreshes, use an Automation.

​
Share or publish

Share the Canvas or the file for access inside your organization. Publish a Canvas snapshot or file snapshot for public readers. Check the published version after updating, including its sources and local interactive controls.
