Registering software copyright in China requires a source code exhibit: the first and last 30 consecutive pages, at least 50 lines per page, a running header carrying the exact software name and version. Miss one detail and the filing comes back for correction. Zhushou turns those rules into a local pipeline and flags the risks before you export.
Requires macOS 14 or later
Your source tree
Source code exhibit
Every requirement below is checked before you export.
Compiled from the published Regulations on Computer Software Copyright Registration and publicly stated review practice of the Copyright Protection Centre of China. This is not legal advice; the registry has the final say.
You see the result at every step. Nothing disappears into a black box.
Drop in a folder, then enter the full software name and copyright holder. Those two drive the header and the attribution check, so they come first. Multiple folders can go into one filing.
Tri-state selection over the directory tree, a breakdown by file extension, and a one-click keep-only filter. Entry files float to the top, or drag to order them yourself.
Strip comments and blank lines, expand tabs, hard-wrap at 78 columns, redact secrets. Change a rule on the left and the before/after diff updates on the right.
A4 simulation with real headers and page numbers, thumbnails marking the seam between the two halves. Pages holding trade secrets can be covered individually.
A three-level verdict: pass, warning, or rejection risk. Findings link to the offending file, and several can be fixed in one click. Then export docx and txt.

Scanning, cleaning, formatting and export all run locally; your source code is never sent anywhere. No account, no telemetry, and no server you have to trust, because Zhushou has no server at all.

The optional tip is handled by the App Store; we never see payment details
Detects API keys, passwords, private IP addresses and mainland mobile numbers, replacing them with placeholders. Add your own regular expressions as needed.
Pages containing trade secrets can be blacked out before submission. Cover more than half the pages and the app stops you, because that exceeds the allowed ratio.
Generates the chapter skeleton for the user manual and design specification from the software details you already entered; fill in the prose and screenshots in Word.
Store the copyright holders and incorporation dates you file under, and apply one to a project in a single click.
Projects you have worked on stay in the library. Settings travel with the project in a .zhushou.json file inside the folder.
Follows the system. The page preview stays easy on the eyes in the dark.
Zhushou will not tell you whether your filing will be approved. It makes sure the formatting is not the reason it is refused.
