DevKit - Dev Swiss Army Knife

A local-first desktop toolbox: JSON formatter, password hashing, Lorem Ipsum, word counter, text formatter, encoding/decoding, AES encrypt/decrypt, digital signatures, image→PNG, plus 4 Gemini-AI tools (grammar fixer, Banglish→Bangla, commit writer, PR writer).

Run it

npm install
npm run start

Make the Windows installer

npm run dist

Produces dist/DevKit Setup 1.0.0.exe — share that single file, nothing else is needed. First build downloads ~150MB of packaging tools; later builds are fast.

Other commands

Command	What it does
npm run start	Open the app in development mode
npm run dist	Build the Windows installer (dist/DevKit Setup *.exe)
npm run dist:dir	Fast unpacked build (dist/win-unpacked/) for testing
npm run make-icon	Regenerate assets/icon.ico from assets/icon.png

Notes

• AI tools need a free Gemini API key: open the app → gear icon (topbar) → paste key, optionally set a model ID (default gemini-flash-latest). Stored only in your localStorage.
• Everything else works fully offline.
• Ctrl + / Ctrl - / Ctrl 0 zooms; Ctrl + wheel too. Theme, font, and text size are in the topbar and the settings modal.
• The installer is unsigned, so Windows SmartScreen shows an "Unknown publisher" warning — click More info → Run anyway.
