ZeroTwo lets you share chats and canvases via a link. Before sharing, it’s important to understand how shared links work — who can see them, what they contain, and how to revoke them if needed.

​
How Shared Links Work

When you create a shared link for a chat or canvas in ZeroTwo:
  • The link is publicly accessible — anyone who has the URL can view the content
  • No login is required — viewers do not need a ZeroTwo account
  • No password protection — there is no access control on shared links
  • No access notifications — you will not be notified who viewed your link or when
This is by design for easy sharing, but it means you should be thoughtful about what you share and with whom.
Shared links are public. If your link is posted on a public forum, indexed by a search engine, or forwarded beyond the intended recipient, anyone can view the content. Treat shared links like public documents.

​
What Is Included in a Shared Link

A shared chat link contains:
  • The conversation text — all messages and AI responses in the chat
  • Any code blocks, tables, or structured output from the conversation
  • The general flow of the conversation
A shared link does not contain:
  • Your memory context — ZeroTwo’s knowledge about you is not exposed to viewers
  • Your custom instructions — your personalization settings are not included
  • Your uploaded files — the file itself is not accessible; only the conversation text about the file
  • Your account details — name, email, and profile information are not shared
Even though files themselves aren’t shared, the conversation may contain summaries, quotes, or analysis from those files. If your file contained sensitive information, the conversation text may still reveal it.

​
Risks to Consider Before Sharing

Review your chat for the following before creating a shared link:

Credentials & API Keys

Never share chats where you pasted passwords, API keys, tokens, or secrets — even if the conversation was about something else. Scrub these before sharing.

Personal Information

Be cautious with combinations of name + address + date of birth, or any information that could be used for identity theft or social engineering.

Confidential Business Info

Internal strategy, unreleased product details, financial projections, client data, or any information under NDA should not be in a public shared link.

Third-Party Information

If you discussed information about other people (colleagues, clients, contacts), sharing that conversation may expose their information without their consent.

Financial & Medical Data

Financial account details, medical records, health conditions, and similar sensitive data should never be in a publicly shared link.

File Contents

Remember that the conversation may summarize or quote from files you uploaded. Even though the file itself isn’t shared, its contents may be visible in the chat text.

​
Revoking Shared Links

You can revoke any shared link at any time. Revoking takes effect immediately — the link stops working the moment you revoke it. To revoke a shared link:
  1. Go to Settings → Data Controls → Shared Links
  2. Find the link you want to revoke (links are listed with their creation date and a preview of the chat title)
  3. Click Revoke next to the link
  4. The link is immediately invalidated — anyone who tries to visit it will see an error
To revoke all shared links at once:
  • In Settings → Data Controls → Shared Links, look for the option to revoke all links in bulk

​
Best Practices for Safe Sharing

Share via direct message, not public posts. When possible, send shared links directly to your intended recipient rather than posting them in public channels, forums, or social media where they can be indexed or forwarded. Revoke links after use. Once the recipient has reviewed the content, revoke the link. This limits the window during which the content is publicly accessible. Audit your shared links periodically. Go to Settings → Data Controls → Shared Links and review what you’ve shared. Revoke any links for chats that are no longer relevant to share or that contain information you’d prefer to keep private. For sensitive work, use alternatives to shared links. Consider exporting your conversation to PDF or copying the relevant text and sharing it directly (via email or a secure document) instead of creating a public link. This gives you more control over who receives the content. Don’t share links that contain credentials. If you realize after the fact that a shared link contains an API key, password, or token, revoke the link immediately and rotate the credential.

​
Business Plan Note

If your organization is on the Business plan:
  • Org admins may have visibility into member shared links per your organization’s data policy
  • Consider informing your team of your organization’s sharing policy so members know what they should and shouldn’t share
  • If your org handles sensitive data, establish a clear policy: what’s okay to share, what requires review, and what should never be shared via public link
