JUST Office is an integrated office suite from Just Systems Corporation that combines word processing (JUST Note), spreadsheets (JUST Calc), and presentations (JUST Focus) with PDF editing and advanced Japanese input tools.

The suite includes ATOK Pro, a sophisticated Japanese input system that adapts to different industries and work contexts, plus document proofreading that catches ambiguous phrasing and date errors.

Just Systems offers specialized editions for government (JUST Government), law enforcement (JUST Police), and healthcare (JUST Medical) with industry-specific dictionaries and templates.

JUST Office uses a perpetual license model with support extending through March 2033, allowing organizations to budget predictably without ongoing subscription fees.
