Automatic organization
Mouzi sits in your system tray and watches the folders you choose. When a new file lands, it applies your rules and moves it to the right place. You keep working; the folder stays clean.

What it does
Small app, sharp behavior.
Mouzi is a small Rust and Tauri tray application. It stays out of the way until a watched folder needs attention.
Custom rules, in your words
Match files by extension and optionally narrow the match with a regular expression applied to the full file name. Destinations can use placeholders such as {year} and {month} to create dated folders.
Read the docs
History and one-click undo
Every successful move is recorded in a local SQLite database. If a rule sends a file somewhere unexpected, open History and undo that entry.
Read the docs
Privacy and security, by design
No cloud, no account and no telemetry. Releases are built in public CI. Mouzi also uses a grace period, skips browser temporary files and checks for file locks before an automatic move.
Read the docs
Privacy
Your files never leave your computer.
Mouzi has no server side. There is nothing to sign up for, nothing to sync and nothing to leak.
No cloud processing
Every rule runs on your CPU, against your disk.
No account
Download, install, done. Mouzi never asks who you are.
No telemetry
The app sends nothing home. You can verify this in the source.
No file names transmitted
File names, paths and contents stay on your machine.
Rules and history stored locally
Configuration and history live in a local SQLite database you can delete anytime.
Open to inspection
The full source code is on GitHub under the MIT license.

Rules
One condition, one destination. That's a rule.
These are real rules from real setups. Click through them to see how Mouzi resolves each destination.

Documentation
Everything you need to make Mouzi yours.
From your first rule to advanced regex patterns and managed deployments.
Security
Releases you can verify.
Public Mouzi releases are built from tagged commits by workflows that anyone can inspect on GitHub.
GitHub Actions builds
Releases are compiled in public CI from tagged commits. The workflow files are part of the repository.
SignPath Foundation
Code signing approval in progress with SignPath Foundation.
Verify the file you received
The security guide explains how to inspect Windows signatures and calculate a local SHA-256 hash. A trusted comparison value is required before a hash can verify a download.

Building a trusted release pipeline for an open-source Windows app
How Mouzi turns a public git tag into Windows and Linux packages, why the Windows executable is signed before the installers and where manual approval fits.
5 practical rules to organize your Downloads folder
A small Mouzi setup for documents, images, screenshots, invoices and installers, with working regex examples and an explanation of rule order.
Why Mouzi processes every file locally
Mouzi watches a folder that may contain invoices, photos and private documents. This is what the app reads, what it stores and why none of it leaves your computer.
