SM Gray Tool Bench

Personal tool hub built with Next.js App Router. The current web bench includes:

• Auto Crop
• BJJ Fanatics Content Cleanup
• Contents.txt Creator
• Playlist Creator
• Audio Splitter via a local Windows helper

Run The Web App

npm install
npm run dev

Open http://127.0.0.1:3000.

Run The Audio Helper

The Audio Splitter keeps the desktop audio flow through a small local helper service.

npm run helper:build
npm run helper:run

You can also double-click start-audio-helper.bat from the repo root.

If you want to use the BAT file:

1. Open D:\Dev\SMGrayToolsWeb in File Explorer.
2. Double-click start-audio-helper.bat.
3. Leave that console window open while using Audio Splitter.
4. Go to the Audio Splitter page and wait for the Helper status to show online.

The helper listens on http://127.0.0.1:43127 and is only needed for the Audio Splitter tool.

Browser Notes

• Auto Crop and Content Cleanup work in any modern browser.
• Contents.txt Creator and Playlist Creator require Chrome or Edge because they use the File System Access API.
• Audio Splitter is designed for Windows and expects the local helper to be running.

Verification

npm run lint
npm run test:unit
npm run build
