# Onlay vs Notion for sharing what your agent made

> Notion is a good home for a team's wiki and can now read comments through its MCP server. When an agent's page belongs in Notion, and when it belongs on Onlay.

Notion is where many teams keep plans and specs, and Notion's MCP server lets an agent read and write pages and comments. If the document belongs in your team's wiki, that is a good path. It is a weaker one for HTML your agent built, and for reviewers outside the workspace.

Checked against Notion's help and developer docs in October 2026; links below.

## Side by side

| | Onlay | Notion |
|---|---|---|
| Keeps your agent's HTML as it is | Yes | No: HTML import drops scripts, embeds and complex layout ([Notion help](https://www.notion.com/help/import-data-into-notion)) |
| Readers need an account to comment | No, unless you restrict the document | Commenting on a public page needs a Notion login ([Notion help](https://www.notion.com/help/share-your-work)) |
| What comes back to the agent | Edits as before and after with source lines, comment threads with quotes, page state | Comments through [Notion's MCP server](https://developers.notion.com/docs/mcp-supported-tools); suggested edits and resolving need a Business plan or above |
| Where the source lives | Your agent's file | The Notion page |

## Choose Notion when

- The document should live in the team's Notion wiki or databases for good.
- Everyone who reviews is a member of the workspace.

## Choose Onlay when

- The output is HTML whose charts, interactions or layout matter.
- Reviewers are outside the workspace: clients, another company, anyone without a login.
- You want rounds of review on the agent's own file: push, comment, pull, push again to the same link.
