Complementary: Zotero plugins and built-ins

paperful

  • Sites: GitHub · this repo

  • Fit: CLI gap-filler. Routed OA stack (including CORE with API key), optional EZProxy and Scholar cookies, opt-in Sci-Hub, collection-mirrored out/ tree, manifest.jsonl, attach on Zotero 10+. Identifier verify (Crossref/OpenAlex/PubMed) + lint + fix-metadata on disk, then adapter write-back.

  • With others: StorScan or Attanger when paths and linked files are wrong; zotero-agent for dedupe.

  • Not a substitute for: In-app plugin UX, or .bib hygiene tools.

Zotero built-in

  • Sites: Zotero · custom PDF resolvers

  • Fit: Per-item Find Available PDF, identifier lookup, duplicate merge UI.

  • With paperful: Built-in capture on save; paperful for batch backfill.

zotero-zotadata

  • Sites: GitHub

  • Fit: Plugin combining attachment validation, multi-source PDF retrieval, and metadata updates.

  • With paperful: Overlapping PDF mission; zotodata stays in Zotero.

StorScan

  • Sites: GitHub

  • Fit: Attachment operations — scan, fix misplaced linked files, merge duplicate files.

  • With paperful: paperful fills missing PDFs; StorScan repairs layout.

ZotMeta

  • Sites: GitHub

  • Fit: Bulk metadata from DOI, ISBN, arXiv; PDF cache identifier extraction.

  • With paperful: Overlaps lint / fix-metadata; ZotMeta is in-app.

Attanger and ZotMoov

  • Sites: Attanger · ZotMoov

  • Fit: ZotFile-era workflows on Zotero 7+ — match downloads, rename/move linked files.

  • With paperful: Incoming-file organisation vs remote PDF hunt.

zotero-agent

  • Sites: GitHub

  • Fit: Local-first CLI and MCP via bridge plugin — search, dedupe, merge, enrich, pdf-fetch.

  • With paperful: Agent for hygiene; paperful for collection runs with manifest and folder mirror.

zotero-mcp ecosystem

ZotFile (legacy)

  • Sites: zotfile.com

  • Status: Not compatible with Zotero 7+. Use Attanger / ZotMoov.

BibTeX, Mendeley, and scripts

bibcite and bibtex-tidy

  • Sites: bibcite · bibtex-tidy

  • Fit: Resolve papers to canonical BibTeX, dedupe, tidy, upgrade preprints.

  • With paperful: Orthogonal until a bib-file LibraryBackend exists.

bibmanager

  • Sites: Read the Docs

  • Fit: Unified BibTeX database, ADS integration, optional PDF fetch from ADS.

Mendeley

  • Fit: Reference Manager Duplicates smart collection; Desktop merge UI. paperful’s manager = "mendeley" is not implemented yet — import or sync into Zotero first.

paperscraper

  • Sites: GitHub

  • Fit: Python metadata + save_pdf from DOIs; publisher TDM API keys.

  • With paperful: paperscraper when the input is a DOI list, not a collection tree.

Choosing in one glance

Need to export PDFs already in Zotero storage to a folder?
  → pyzotero dump (not paperful)

Need tablet send/get after ZotFile died?
  → ZotMoov custom menus (+ Attanger)

Need LLM to fix one paper’s metadata while writing?
  → zotero-mcp

Need reproducible .bib for a paper submission?
  → bibcite fix / bibtex-tidy
