Contract.docx, Contract final.docx, Contract final (1).docx and the PDF you exported. SimilDoc reads the text of your documents, recognizes which ones are the same even when the name or format changes, and puts each document in its own folder. All of it happens on your computer.

A folder like yours: 10 files in a mess. Press the button to see how SimilDoc groups them.
SimilDoc is a desktop app for Windows and Mac that finds documents saying almost the same thing and sorts them. It is for that moment when five versions of the same file are scattered across a folder and you no longer know which one is the right one.
It does not look for files that match by name or size, the way duplicate finders do. It reads the text of every document and compares it with all the others, so it recognizes a contract even when it has another name or another format.
Four steps. Your disk does not change until the last one, and only if you confirm.
Drag it onto the window or browse for it. Include its subfolders too if you want.
It extracts the text of each document and compares it with every other one. Two documents land in the same group when they are 90% similar or more.
You see every group, with how similar each file is. Grouped too much or too little? Move the similarity slider and the groups rebuild instantly.
Copy leaves your originals where they are and builds the sorted folder next to them. Move actually tidies them. Either way, a report records everything that was done.
Files with no match go to “Únicos” and files that could not be read go to “No legibles”. Nothing is left loose, and your original files are never renamed. The folder names and tags (guardado means saved, clon means clone) are in Spanish, like the app.
SimilDoc has no server. We are not promising not to look at your files: there is simply nowhere for them to be sent.
Guaranteed by design
The app does not connect to the internet to work. The whole analysis runs on your machine, start to finish.
Guaranteed by design
It only copies or moves. If a name is already taken, it adds (2) instead of replacing the file.

Windows may show “Windows protected your PC”, because the app is not signed with a Microsoft certificate. Click “More info” and then “Run anyway”. It only happens the first time.

Unzip the file and drag SimilDoc to Applications. Since it is not signed with an Apple certificate, macOS will block it the first time: go to System Settings, Privacy & Security, and click “Open Anyway”. It only happens once.
The app’s interface is in Spanish for now. An English interface is planned.

Write to us and we will work out a professional license. Your documents would still never leave your computer.
This is a summary. The license text is what counts. Read the full license
Yes, for personal and nonprofit use. There is no paid tier, no trial period and no locked features. If you plan to use it in a business, write to us.
No. SimilDoc runs inside your computer and sends nothing to the internet. We have no server that receives documents, so there is no way for them to reach us. You can check it by using the app offline.
It never deletes or overwrites anything. It only copies or moves, and always after showing you the groups and asking you to confirm. On your first run, use Copy: your originals stay exactly where they are.
You see it before anything moves. You can ask for more or less similarity before files are grouped, and the groups rebuild on the spot. SimilDoc compares text, so it gets it right most of the time, but it is not infallible: you have the final say.
PDF, Word (.docx), TXT and Markdown. PDFs scanned as images have no text to read and end up in “No legibles”. Files over 100 MB are skipped.
Most likely, because the app is not signed with an Apple or Microsoft certificate. It is a normal warning for apps downloaded outside a store. The Download section has the steps; you only do it once.
Not yet. The app is in Spanish for now, and an English interface is planned. Grouping works the same with documents in any language that uses text.
It works the same. Just keep in mind that if you reorganize a synced folder, your service will sync those changes like any other file you move. To start, try Copy on a small folder.
The app keeps working. It does not depend on any server or on an online license that someone could switch off.
If something was grouped badly, a file was not read or the app closed, tell us and we will look into it.
Your email app opens with a template: your system, the steps and what happened. That is almost always enough.
Write the reportWe do not need them to fix a problem and we will never ask for them. The steps and the error message are almost always enough.
