Find it from what you remember.
Understand it. Build with it.
FIND
KeyLen Finder
You never lost the file. Only its location.
KeyLen Finder indexes the folders you choose, so you can start from a word you remember.
Local · Fast · Private. No network access of any kind.
Found. And now?
A file you can open is not yet a document you understand.
UNDERSTAND
KeyLen AI
From document to understanding.
KeyLen AI reads it and hands back structure — what it says, where the risk is, what to look at next.
Your PDF is parsed on your device. Only the extracted text is sent for analysis — the original PDF file is never uploaded, and the file name is not sent.
Understood. And now?
Understanding that is never captured is understanding that evaporates.
BUILD
KeyLen Studio
KeyLen Studio is the capability engine behind KeyLen AI — what lets its analysis keep evolving.
