OG Image

You can set a custom OG image by:

  1. Clicking the OG Image field in the sidebar.
  2. Uploading a new image or pasting a URL.
  3. The recommended size is 1200×630px.

If no custom OG image is set, the system uses paper.thumbnailUrl first, then falls back to the default app logo.


How Custom Values Override Auto Tags

When a paper has custom metadata set, the system uses those values directly for the corresponding fields. Fields not explicitly set in custom metadata still use auto-inferred values.

The resolution priority for each field:

  1. Custom metadata value (if set and non-empty).
  2. Inferred value from paper body/title.
  3. Framework default.

Viewing the Result

After saving custom metadata:

  1. Check the Auto Tags page for details on the full output structure: Auto Tags.
  2. View the page source or use your browser's DevTools to inspect the rendered <head>.
  3. Use the Facebook Sharing Debugger or Twitter Card Validator to preview social shares.
