# Link previews and oEmbed

> What other tools show when someone pastes a Blueprintr link, and how to make it a live embed.

## Link previews

Paste a public blueprint's URL into a chat tool, a wiki or a social post and it
unfurls: title, description and a preview image of the diagram.

The preview image is generated from the blueprint itself, so it shows the
actual drawing rather than a generic card.

## oEmbed

Blueprintr is an oEmbed provider. Tools that support oEmbed can turn a pasted
link into a live, interactive embed rather than a static preview. It is the
same frame described in [embedding](/foliums/blueprintr-user-guide/sharing/embedding-blueprints),
with no iframe snippet to copy.

Support varies by tool. Where a tool does not recognise the provider, the link
falls back to an ordinary preview.

> [!NOTE]
> The embed URL is built from the **author's** handle. For an organisation
> blueprint that is not the same as the organisation's slug, so copy the URL
> from the Share panel rather than constructing it.

## Private content

Only public and unlisted content unfurls. A private blueprint's link shows
nothing beyond the URL. An unfurl in a chat channel would otherwise leak the
title to everyone in it.
