Fabric vs Lattuce — AI second brain or cited academic writing?
Compare Fabric and Lattuce for AI workspace, deep search, and academic writing with citations and Word export.
Fabric is an AI workspace for notes, files, search, and agents — a cloud "second brain" with deep search, canvas, and apply-preview AI edits. Lattuce overlaps on notes, whiteboards, and Ask, but connects them to PDF sources, citation-verified compose, and Word export at lattuce.app.
If you love Fabric's unified capture and search, the question is whether you need a personal knowledge hub or research that ends in cited papers.

When to use both
Keep Fabric for visual bookmarking, meeting notes, and cross-cloud search. Use Lattuce when boards and notes should feed papers with real citations at lattuce.app.
Bottom line
Choose Fabric for a polished AI second brain with minimal setup and broad integrations. Choose Lattuce when research should end in cited writing and bilingual translation in the cloud.
