Nexus Pad Desktop scratchpad for text transforms

Paste text.Run the right script.

Nexus Pad is a desktop scratchpad for the work people actually do all day: quick transforms, JSON reshaping, Markdown previews, JWT inspection, and custom scripts that stay close to the editor instead of disappearing into a plugin maze.

What it does

The whole scratchpad, organized around the text.

Nexus Pad is not a general-purpose suite. It is a focused desk for the transformations that keep showing up: open text, run a script, inspect the result, keep moving.

↔Permanent drawer

The left rail keeps tools and scripts visible, searchable, and one click away. Recents, favorites, and the full library all stay in reach.

□Plain text editor

The center pane stays simple: paste, edit, transform, and keep the native undo stack intact while scripts rewrite the buffer.

{}JSON screen

Format, minify, expand, collapse, compare, and switch between tree, text, and type views without leaving the document.

Markdown preview

Write on the left, preview on the right. The sandboxed iframe keeps the rendered output isolated and predictable.

◌JWT tools

Decode and encode tokens, inspect the signature state, switch claim layouts, and keep secrets and timestamps close to the token itself.

⌘Keyboard-first flow

Search, scripts, tabs, and screens are built around shortcuts so the hands stay on the keyboard when the job is repetitive.

★Favorites and recents

Frequently used scripts rise to the top. Star the ones you trust and the drawer becomes a personalized toolbox instead of a long list.

⚙Preferences window

Theme, syntax palette, scripts folder, and shortcut bindings all live in a dedicated settings window instead of cluttering the editor.

Workflow

Drawer, editor, screens, scripts. Everything stays close.

Nexus Pad keeps the work visible instead of hiding it behind menus. You can browse scripts from the drawer, transform the current buffer in the editor, and switch to a focused screen only when the content calls for it.

Paste textEditor buffer
Pick a scriptTransform result
Open a screenJSON, Markdown, JWT
Tune settingsTheme, palette, shortcuts

That is the loop the release is built for: inspect the text, transform it, switch tools only when needed, and keep moving without losing the buffer.

Engine

Built like the app: Tauri on top, native work underneath.

Nexus Pad keeps the webview light. Scripts run off the main thread, the editor stays undo-safe, and the Rust side handles the native pieces the browser should not own.

That split keeps big scripts from freezing the editor and lets the release builds stay lean.

Honest scope

Nexus Pad is proud of what it already does: editor transforms, JSON tools, Markdown preview, JWT handling, shortcuts, and custom scripts. The homepage says that clearly instead of pretending the app is a generic platform.
