TextSeek Personal 2.5.1853 (Win&Mac) was available as a giveaway on March 8, 2019!
Character-level desktop search tool for the document contents on Windows and Mac OS, supporting PDF, Word, Excel, PowerPoint and other formats.
The core feature is that TextSeek can perform search character-by-character with no omission, which is quite different from common indexing tools.
It's annoying that after long Windows Search you are told there is no results even some files are just under your nose. By introducing advanced indexing engine, TextSeek can overcome this problem. It performs full-text scanning within several seconds, and render the search results like Google.
Please note: the program includes the three year license!
Windows above XP (x32/x64); Mac OS (above EI Capitan, only 64 bits); 1 GHz or faster processor, 150 MB RAM and 300 MB hard disk space
