These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For changelogs, announcements and blog posts shared as GIF or MP4. The full title is laid out first, so lines never jump while it types, and it holds complete for the last quarter of the clip. A still format shows the whole title with no caret.
Fields
Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.

accent and theme change per request. For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.
