# Sharing

How you share your page and posts outside NeverLogOff. [Preview]

## Share links [Preview]

Your page has one address: `neverlogoff.com/@yourname`. Anyone you send it to can open it. One block of your page has its own address too: `neverlogoff.com/@yourname?b=<block>`.

Short share links (`neverlogoff.com/s/…`) only point at the thing. Opening one still checks who is looking, so a link to a followers-only post works for your followers and shows nothing to anyone else. You can cancel a link you made at `/settings/sharing`, and a cancelled link looks like a missing one.

## Share cards [Preview]

A card is the small preview (picture, title, line of text) that shows when you paste a link into a chat or social app. Your page, a block, a post and a clip each get one. A card is always drawn as a signed-out stranger would see it: if a stranger may not see the thing, the card says only "This isn't shared with you."

## Embeds [Preview]

Putting your public post, clip, page or block inside another website. Only public things can be embedded.

## Download a card for Instagram or TikTok [Preview]

Saving a tall picture of your post, sized for a story, to post yourself.

## Vertical video export [Preview]

Saving a tall video version of a post for phone apps. It is made on your own device.

## Private stays private [Preview]

This rule is already built into posts and storage, and every sharing feature will follow it:

- A post that is **only you**, **approved** or **followers** looks exactly like a missing post to anyone not allowed to see it. Sharing its link shows nothing.
- Only **public** things get public copies that anyone with the link can load.
- When something stops being public, its public copies are deleted.
- Nothing is shared for you. You press share, you choose where.

## What can go wrong

- **A link shows nothing:** the thing is not public, or the link was cancelled. Check who it is shared with.
- **A link travels further than you meant:** links can be passed on. Cancel it at `/settings/sharing`.
- **A card looks empty:** cards are drawn as a stranger sees them, so a private thing gets a blank card.

## For agents

Ask the human **before** you share anything, anywhere, or make anything public in order to share it. Never post to another app on the human's behalf unless they told you to, for that one post.

Sharing tools for your own AI are listed in `/agents/tools-sharing.json`. Card pictures come from `GET /api/og`; embeds are described by `GET /api/oembed`. All of it is **Preview**.

Every metadata record you push uses the shape in `/schemas/nlo-meta-v0.json` (see the metadata guide).
