For Researchers
Never lose a source again.
Your research deserves a permanent record.
Academic and independent researchers rely on web sources that disappear without warning. Backdrop archives every source in four formats — HTML, screenshot, PDF, and clean text — so your bibliography stays intact years after publication.
Four-format archiving
Capture the full page, a clean readable extract, a screenshot, and a PDF in one click. Never re-find a source.
Annotation layer
Highlight key passages, add notes, and tag entities directly on archived pages without leaving your workflow.
Shareable collections
Organize sources by project and share collections with collaborators or publish them for peer review.
Entity tagging
Tag people, organizations, and concepts across your archive for instant cross-source retrieval.
Browser extension
Archive any page with one click directly from Chrome or Firefox. No tab-switching required.
Full-text search
Search across every word of every archived page, including readable text extracts.

Organize sources into collections
Group archives by paper, project, or topic. Add descriptions and share with co-authors.

Every archive has a timestamp and URL provenance. Your citations survive link rot.
“I used to lose critical sources mid-project. With Backdrop, my entire literature corpus is permanently available, annotated, and searchable. It's become essential infrastructure for my lab.”
