Bundle your files and directories into a clean, token-optimized context prompt for Claude, ChatGPT, and Cursor. Runs 100% locally in your browser.
No. This tool runs 100% locally in your browser using the native HTML5 File API and JSZip. Your files never leave your device, meaning confidential source code, proprietary algorithms, and sensitive internal scripts remain completely private.
Both Anthropic (Claude) and OpenAI strongly recommend using distinct XML tags (such as <file path="...">) to wrap multi-file codebases. Unlike markdown backticks, which can clash with existing code blocks inside your files, XML boundaries provide unambiguous separation between instructions, file metadata, and actual file contents.
To save valuable prompt tokens, this tool automatically filters out dependency directories (such as node_modules, dist, .git), lockfiles (like package-lock.json), and binary files (including images, audio, video, and fonts).
Progressier abstracts your manifest, service worker, and caching logic so you can deliver native-feeling web applications effortlessly.
