How it works
Metadata comes from Crossref, which covers journals, bioRxiv and the newer openRxiv DOIs. Paste DOIs or article URLs, one per line — the DOI is pulled out of the URL automatically, and PMC links are resolved through NCBI first.
Paste the generated text into the Bluesky composer with the full URL — the composer shortens it for display, which is what the character count already assumes.
Set the hashtag per paper with the dropdown on each row.
