Common questions
Common questions about Sciwheel vs Zotero
Is Sciwheel the same thing as Lean Library Workspace?
+
As of this writing, sciwheel.com presents the product under the name "Lean Library Workspace" while the domain and underlying service are unchanged. Expect the rebrand to be inconsistently reflected across the vendor's own pages, third-party reviews, and institutional library guides for a while — check the vendor's current site directly if a specific feature or price seems out of date.
Does Sciwheel have a free tier?
+
Yes, a "Starter" tier is free but limited to up to 3 active projects, per sciwheel.com/pricing. Unlimited projects require the $6.99/month Premium tier or an institutional Lab Group license.
Can I migrate a library between Sciwheel and Zotero?
+
Both support standard citation interchange formats (such as RIS/BibTeX export), so a library's bibliographic metadata can typically move between them. Test a migration with a small subset first if the library has extensive annotations or highlights, since those are more likely to need manual cleanup than plain reference metadata.
Which has better Google Docs support, Sciwheel or Zotero?
+
Both currently offer a Google Docs add-on according to their own sites, so this is not a strong differentiator between the two the way it is between Zotero and Mendeley (whose citation add-in is Word-only). The bigger practical differences between Sciwheel and Zotero are cost model and storage, not word-processor coverage.
