Write documents, work with spreadsheets and build presentations offline.
Write documents, work with spreadsheets and build presentations offline.
Create and edit everyday documents, spreadsheets and slide decks locally. Replaces the desktop document-creation slice, not Microsoft or Google email, meetings, cloud storage, tenant administration or exact complex-format/macro compatibility.
Proprietary software. No included hosted email, Drive/OneDrive replacement or live cloud collaboration. Advanced SoftMaker Office features are separate. Complex Microsoft formatting, macros and add-ins need compatibility checks; the cited hands-on review is of the older 2018 release.
Each comparison covers the workflow described above, rather than every paid feature.
