Your Source to Prompt is a single .html file that runs entirely in a modern browser and lets you locally select files and folders to combine into a single, structured prompt for LLMs. Everything runs client-side, so your code never leaves your machine.
Key features
- Fully local & secure: uses the File System Access API; no servers or tokens required.
- No install: just download the HTML and open it in a Chromium-based browser.
- Presets & export: save/load selection presets and export/import JSON for reproducible workflows.
- Selection & minification: powerful string filters, bulk selects, and optional minification to reduce context size.
Use cases
- Prepare private codebases or sensitive projects for LLM-assisted refactoring without uploading source code.
- Quickly combine multiple files into a single prompt for review, debugging, or documentation generation.
Technical notes
- Builds a file tree using the browser File System Access API and respects
.gitignore-style filtering. - Shows size/line-count tallies and warnings when selected content may exceed common LLM context windows.
- Uses client-side minifiers (Terser, csso, html-minifier-terser) to reduce payload size when needed.
