# Share Canvas

> Generate a public read-only link for any canvas — anyone with the link can view the document without a ZeroTwo account.

Every canvas you create in ZeroTwo can be shared as a public read-only link. The link opens the canvas in a clean viewer — no login required, no chat history visible. Share reports, code, diagrams, or any canvas content with anyone, instantly.

<Warning>
  Shared canvas links are **fully public with no access control**. Anyone who has the URL can view the canvas — no password, no login. Do not share canvases containing passwords, sensitive personal data, confidential business information, or private keys.
</Warning>

## How to Share a Canvas

<Steps>
  <Step title="Open the canvas">
    Make sure the canvas panel is open. If it is not visible, click the Canvas pill in the prompt bar to reopen it.
  </Step>

  <Step title="Click Share in the canvas toolbar">
    In the top-right of the canvas panel, click the **Share** button (share icon).
  </Step>

  <Step title="Copy the link">
    A link is generated in the format `/share/canvas/:canvasId`. Click **Copy link** to copy it to your clipboard.
  </Step>

  <Step title="Send the link">
    Paste the link into an email, Slack message, document, or anywhere else. Anyone with the link can open and read the canvas immediately — no ZeroTwo account required.
  </Step>
</Steps>

## What Viewers See

When someone opens a shared canvas link, they see:

* The full canvas content rendered in read-only mode
* All formatting, tables, code blocks, diagrams, and other elements rendered correctly
* The canvas type displayed in its native viewer (Rich Text, Code, Spreadsheet, Diagram, HTML)

What viewers do **not** see:

* The chat conversation that created the canvas
* Your ZeroTwo account, profile, or any personal information
* Any edit controls, AI actions, or canvas toolbar buttons
* Other canvases or chats in your workspace

<Note>
  Sharing a canvas does **not** share the associated chat conversation. Only the canvas document itself is visible to viewers. The chat remains private to your account.
</Note>

## Share Link Format

Shared canvas links follow this URL pattern:

```
https://zerotwo.ai/share/canvas/:canvasId
```

The `:canvasId` is a unique identifier generated for each canvas. Each canvas has its own share ID. If you click Share again on the same canvas, you get the same link.

## Managing Shared Links

### Viewing All Your Shared Links

<Steps>
  <Step title="Go to Settings">
    Click your avatar or profile icon, then select **Settings**.
  </Step>

  <Step title="Open Data Controls">
    Navigate to **Settings → Data Controls**.
  </Step>

  <Step title="Find Shared Links">
    The **Shared Links** section lists all active canvas share links, including the canvas title and the date it was shared.
  </Step>
</Steps>

### Revoking a Shared Link

If you need to stop sharing a canvas — because the content is outdated, was shared by mistake, or contains information you want to retract — revoke the link at any time.

<Steps>
  <Step title="Go to Settings → Data Controls → Shared Links">
    Find the canvas link you want to revoke in the list.
  </Step>

  <Step title="Click Revoke">
    Click the **Revoke** button next to the canvas link.
  </Step>

  <Step title="Link is immediately deactivated">
    The link becomes dead instantly. Anyone who tries to open it sees a "not found" page. There is no delay.
  </Step>
</Steps>

<Note>
  Revoking a link does **not** delete the canvas. The canvas remains in your ZeroTwo workspace. Only the public share link is disabled. You can generate a new share link for the same canvas if needed.
</Note>

## Link Behavior

| Property                  | Behavior                                                                                       |
| ------------------------- | ---------------------------------------------------------------------------------------------- |
| **Expiry**                | No expiry by default — links remain active until you revoke them                               |
| **Authentication**        | Not required for viewers — anyone with the URL can open it                                     |
| **Access control**        | None — no password protection, no allowlist                                                    |
| **View tracking**         | Not available — you cannot see who viewed or how many times                                    |
| **Updates**               | The shared view reflects the current state of the canvas — edits after sharing will be visible |
| **After canvas deletion** | Link shows "not found" — cannot be restored                                                    |

| **Documentation drafts** | Share a document draft for async feedback before finalizing                                       |
| **Code review**          | Share a code canvas for review without needing to paste code into another tool                    |
| **Public resources**     | Share tutorials, templates, or reference materials broadly                                        |

## Privacy Considerations

<Warning>
  Before sharing, ask yourself:

  * Is this content appropriate to make fully public?
  * Could the URL be guessed or discovered by others? (Unlikely — the canvas ID is random, but not impossible to share accidentally.)
  * Does the canvas contain anything I would not want a stranger to read?

  If any answer gives you pause, export the canvas as a file (PDF, DOCX, etc.) and share it through a secure channel — email with access controls, a shared drive with permissions — instead of a public link.
</Warning>

<Tip>
  Revoke shared links when sharing is done, especially for content that is time-sensitive or sensitive-adjacent. This is good hygiene even when the content seems low-risk.
</Tip>

## Frequently Asked Questions

<Accordion title="Can viewers edit the shared canvas?">
  No. Shared canvas links are strictly read-only. Viewers cannot make any changes to the content, add comments, or interact with the AI.
</Accordion>

<Accordion title="Does the shared canvas update if I edit the canvas after sharing?">
  Yes. The shared link reflects the current state of the canvas. If you continue editing the canvas after sharing, viewers who open the link will see the updated content.
</Accordion>

<Accordion title="Can I share a canvas without being logged in?">
  No. You must be logged into ZeroTwo to generate a share link. However, the people you share the link with do not need a ZeroTwo account to view it.
</Accordion>

<Accordion title="What happens to shared links if I delete the canvas or the chat?">
  If the underlying canvas is deleted, the shared link will show a "not found" page. The link cannot be restored once the canvas is deleted.
</Accordion>

<Accordion title="Is there a limit on how many canvases I can share?">
  There is no enforced limit on the number of active shared links on Pro+ plans. Manage all active links from Settings → Data Controls → Shared Links.
</Accordion>
