It’s all about consistency
Consistent documents make a better impact
Documents that have inconsistencies in things like spelling, numerals, hyphenation, and capitalization look sloppy and unprofessional and can affect your reputation. A tiny mistake can have big consequences. Consistency checks are time-consuming but essential.
PerfectIt saves you time finding and fixing mistakes
PerfectIt scans your whole document for difficult-to-locate errors, such as missing acronym definitions, capitalization inconsistencies, and common misspellings. This saves hours of manual checks and frees you up to focus on more substantive work.
