DuckDuckGo has introduced optional chat sharing in Duck.ai, allowing users to send a link to an AI conversation without requiring the recipient to create an account. Recipients can read the shared content, continue it in their own chat, or save a copy. The feature is available at Duck.ai.
How sharing works
Users can select the share icon beneath an AI response and choose to share only that response or the conversation up to that point. A full chat can also be shared from its three-dot menu. Recipients receive an interactive copy: their follow-up messages remain separate from the sender's later conversation. Generated images can be included, but uploaded files are not shared.
Encryption: the decryption key lives in the link
DuckDuckGo says a conversation is encrypted on the user's device before being uploaded. A share URL contains a resource identifier and a decryption key stored in the URL fragment after the # character. Browsers ordinarily do not send that fragment as part of HTTP requests, so DuckDuckGo says its servers can retrieve the encrypted chat without receiving the key. The company also says it tested its telemetry and logging to avoid collecting the key. This architecture reduces provider access to shared content, although recipients who possess the full link can decrypt and read it.
Why shared chats are designed not to appear in Google
For SEO and AI Search, a notable design choice is that Duck.ai shared-chat pages include search-engine noindex directives both in the page and in the server response. DuckDuckGo says these pages are unlisted and use long, random URLs. The intention is to prevent publicly accessible share pages from becoming indexed search results. Noindex is a crawler instruction rather than a cryptographic privacy guarantee: anyone with the working link can still access the chat.
Links expire after 48 hours by default
The default expiry is 48 hours, with alternatives of 1, 2, 7 or 30 days. Users can review and delete links in Duck.ai Settings → Shared Chats, and the Fire Button can remove shared links. DuckDuckGo says encrypted shared chats are deleted from its servers when their links expire. A recipient who saved a copy before deletion can retain it.
Why DuckDuckGo built this feature
Sharing AI output by copying and pasting produces static text. Duck.ai's approach lets another person continue a conversation while keeping their new messages separate. DuckDuckGo frames this as a way to add collaboration without abandoning its privacy-focused architecture.
Privacy limitations users should understand
Encryption and expiration do not prevent a recipient from copying, screenshotting or forwarding information. Share links should therefore be sent only to intended recipients, particularly when chats contain personal or commercially sensitive information. Unlisted does not mean inaccessible, and expiration does not erase copies already saved elsewhere.
What this means for AI Search and publishers
Duck.ai is treating conversation sharing as a private distribution channel rather than a source of publicly indexable pages. That distinguishes shareable AI content from ordinary web publishing. For SEO professionals, the case illustrates how noindex, URL design and retention policies intersect with AI-generated content distribution. It does not establish a new Google ranking factor or imply that shared Duck.ai chats should be optimized for organic discovery.
The NetContentSEO takeaway
AI products are becoming more collaborative, but visibility and privacy are separate product decisions. Duck.ai's encrypted, expiring, non-indexed links show one approach: conversations can be portable and interactive without deliberately becoming searchable public documents.
