TextSeek 2.5.1583 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This Mac application is a product of Zest Company.
From the developer:
Character-level desktop search tool for document contents on Windows and Mac OS within seconds, 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.
