A link you paste into a message expands into a card below it. Most links get a card built from the page's own metadata: host, title, description, and image. Some kinds of link get a card built for them.
GitHub
A GitHub link is recognised as one of seven kinds, and each shows different facts:
| Kind | Card | What it shows |
|---|---|---|
| Repository | GitHub repository | Language, description, stars, forks, last update |
| Issue | GitHub issue | Number, Open or Closed, author, comment count |
| Pull request | GitHub pull request | Number, Open, Closed, Merged, or Draft, branches, commits, files changed, lines added and removed |
| Workflow run | GitHub workflow run | Workflow name, run number, result, branch, who started it |
| Commit | GitHub commit | Short hash and commit date |
| File | GitHub file | Language, path, branch or ref |
| Release | GitHub release | Tag, name, Pre-release or Published, publication date |
Public repositories work with no setup. A link to a private repository needs two things: private previews turned on for Spaces by an administrator, and a GitHub connected account of your own. Without them the card offers Connect GitHub to preview this with Connect account, or one of GitHub App installation needed, Access restricted with Request access, or External previews are off for this room. A private-repository card is resolved for you alone and is never shared with anybody else in the channel; it answers at repository level, so a link to a file or a run inside a private repository shows the repository.
Other cards built for the source
- Research and reference: Scholarly article, arXiv preprint, PubMed article, Book, Wikipedia article, Clinical trial, research organizations, EUR-Lex acts, and security advisories.
- Media: YouTube, TikTok, Vimeo, Loom, and Spotify.
- Recognition only, with no content read from the site: X, Reddit, LinkedIn, Instagram, Microsoft 365, and Google Workspace. These cards name the kind of thing and offer Open on {{platform}} or Open in {{provider}}.
- Meeting invitations, shown as Meeting link with Open meeting link and no meeting detail.
- Evolve's own records: a decision you can acknowledge from the card, a ticket, a Drive file, and a link to another channel or thread.
Turning previews off
- For one message: a checkbox appears under the composer when your draft holds a link. Clear Show link previews before sending. It returns to on for your next message.
- For every message you see: open Spaces settings and clear Show previews for links shared in messages. under Link previews.
- For a message already sent: its actions offer Hide preview, Remove previews for everyone, and Restore previews.
When a card does not appear
- Preview blocked with This link is not eligible for a preview.
- No preview available with No Open Graph or Twitter Card metadata was available.
- This link is private, needs sign-in, or does not exist.
- Preview expired and Card type not supported ask you to reopen or update.
- Not shared with this conversation appears for an Evolve record the channel cannot read. The card offers a way to copy an access request for its owner.
