A Powerful Text Search Engine
SeekFast saves you time with its powerful text-based search capabilities, helping you find the files you are looking for in seconds.
Its unique logic shows you the most relevant results first, similar to that of a Google search. SeekFast technology has no equivalent in the world of file searching!
SeekFast is compatible with all modern Windows versions (Windows 7, Windows 8, Windows 10, Windows 11), and with all commonly used macOS versions.
Ease of Use
SeekFast allows you get the file names and sentences containing your search words immediately. For greater convenience, search terms are highlighted in red. You can open the corresponding file with one click. If you want to view only the text, you can click on the phrase and see the text surrounding it. This allows you to get a quick overview of the text in its file.
SeekFast is integrated with File Explorer - just right-click a folder and choose "SeekFast...". The application starts and you can immediately search the selected folder.
SeekFast is extremely useful for searching in large software projects. When thousands of files are available, it is extremely difficult to find a function, variable, or text throughout them. With SeekFast this happens in a second, which can save you many hours of digging and searching in the programming in your files.

SeekFast is the best doc searcher I have ever used in terms of speed and stability. Thanks for your great software to improve my productivity!

As part of my professional and also personal activities, I have to manage a very large quantity of documents in multiple formats. When you need to search for a document with a keyword in this mass of documents, your software does the job with incredible precision. The reliability of your software is almost perfect. In other words, this software, in the rapid search of documents represents for me an essential tool.

I find it hard to believe that in 20 years of hunting for a search engine that does what I want that SeekFast would be the ticket! I have downloaded at least a dozen programs over the years, but none did the job I needed and ALL of them did that tiresome indexing that was of little help for my needs. Now you have solved it for me!

Count me as a HUGE fan and endorser of the software!

I think I could sell it to anyone who wondered what it would do.
