Drag in a folder or individual source files (HTML, CSS, JS, Python, Swift and more) and get a properly formatted .txt deposit for U.S. Copyright Office filing per 37 CFR § 202.20. Auto-detects programs over 50 pages and extracts the first and last 25 pages as the rules require, and generates the title block with program name, version and author. 100% client-side — your code never leaves the browser.
On Mac, Windows, Linux or any computer: just click "Open Code Deposit" above — it runs right in your browser, no install needed. To keep it like a desktop app, click the install icon (⊕) at the right of Chrome or Edge's address bar, or use Safari's File → "Add to Dock" on a Mac.
On iPhone or iPad: open it in Safari, tap the Share button, then "Add to Home Screen." It behaves like a native app — full-screen, offline-capable, launches from your home screen.
