What our customers say

I've been looking for a program to do this literally for years! Great program! I have lots of different versions of notes and pieces of a writing project and this helps me find the relevant ones quickly. Well done!

SeekFast is amazing at finding keywords in PDFs. I've used it to find projects that used certain aspects in 100s of files. It has saved me a ton of time searching. I can only speak to PDFs, but it works fantastically!

The support I received from the SeekFast team is unparalleled. I’m just one customer, yet they worked patiently to help me restore the internet access I needed to activate my license.

I need to keep all drafts of all of my work electronically, so there are thousands of files in dozens of folders on my computer. Seekfast enables me to quickly locate specific as well as multiple versions of any of my works. It's an invaluable tool.

Almost all scientific articles are available in PDF format. SeekFast can search for text phrases and strings in such files, doing it better and faster than Windows and Adobe Acrobat.

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!

SeekFast is an excellent, simple-to-use application with a large array of file types that it can search. The ability to upload a list of keywords was also a time saver, as this allowed us to look through thousands of files.
