Embed badges
Add a live preprints.ai grade badge to your paper page, profile, or preprint server with a single line of HTML. Free, unauthenticated, auto-updating.
Basic badge (SVG)
Drop this anywhere that accepts HTML. The SVG updates automatically — no JavaScript required.
<img src="https://preprints.ai/badge/10.1101/2025.01.15.633214"
alt="preprints.ai grade">Any DOI works. The badge shows "—" if the paper has not yet been assessed.
Clickable badge
Wrap the badge in a link so readers can click through to the full assessment:
<a href="https://preprints.ai/report/10.1101/2025.01.15.633214">
<img src="https://preprints.ai/badge/10.1101/2025.01.15.633214"
alt="preprints.ai grade">
</a>Variants
Add a ?style= query param to change the badge:
?style=flat— flat square (default)?style=large— larger badge for hero sections?style=compact— letter-only, no text?theme=dark— dark-background variant
Preprint servers
If you run a preprint server and want to add badges to every paper page, contact us — we can set up a partner integration that auto-matches papers and adds the badge without per-DOI configuration.
Open Graph image
Every assessment also has a shareable Open Graph card, suitable for social media previews:

Badges are free to use. No attribution or API key required. Please don't hotlink from very high-traffic pages without telling us — we'll happily whitelist you for unlimited rendering if you need it.
