Every tool in the DataTools research toolkit. Free, no signup, no stored data — each one runs as a stateless server function.
Verify every link in a reference list
Paste or upload up to 500 URLs, DOIs, or arXiv IDs. Each one is fetched server-side and classified by HTTP status, with Wayback fallback links for anything broken.
Pull URLs from BibTeX or RIS
Drop a .bib or .ris file and extract every URL field into a clean, deduplicated list ready to feed into the URL Checker.
Catch DOIs that resolve to a 404
DOIs can resolve successfully but land on a missing publisher page. We follow the full chain and flag the silent failures.
Best archive.org snapshot per URL
For any URL, find the closest Wayback Machine snapshot to a target date — useful for replacing rotted links in manuscripts.
Compare two reference lists
Diff two bibliographies and see what was added, removed, or changed between manuscript versions or review rounds.
Map sources to archives & repos
Group source URLs by hosting platform (GitHub, OSF, Zenodo, Dataverse, journal) so you can audit reproducibility coverage at a glance.
Read long README & .md files, beautifully
Open README, CHANGELOG, or any Markdown document and read it with clean typography, GitHub-flavoured tables, code blocks, and an auto-generated table of contents. Built for very large files.
