Texpander AI

Texpander AI is a robust, Neo Zen-styled userscript that supercharges your typing experience across the web. It provides instant text expansion algorithms and integrates an AI model (Gemini 2.5 Flash Lite) for fast, context-aware text transformations like grammar fixing, summarizing, and expanding content.

This userscript is built with TypeScript and bundled using Vite.

Features

Text Expansion Palette (Alt + P): Define custom abbreviations (e.g., brb -> Be right back.) and trigger them globally.
AI Context Menu (Alt + G): Highlight text anywhere on the web, hit Alt+G, and instantly run AI prompts (Summarize, Fix Grammar, Make Formal) to manipulate your text. Supports custom API prompts.
Neo Zen UI: A beautifully clean, dark, and highly responsive user interface free of sluggish animations—engineered for immediate flow state.
Configurable Settings: Fully customize your AI preferences, API keys, and text expansion dictionary right in the browser.

Getting Started

Prerequisites

You will need a userscript manager installed in your browser:

Installation

Since this project is managed by Vite with the vite-plugin-monkey plugin, you can install the script locally while developing.

Clone & Install Dependencies
```
npm install
```
Development Runs the Vite development server. Your userscript manager will typically pick up the local file, updating automatically as you make changes.
```
npm run dev
```
Build target Compile down to a single minified userscript file inside the dist/ directory.
```
npm run build
```

Once built, you can drag and drop dist/texpander-ai.user.js into your userscript manager to install the production version of the extension.

Usage

Open the Text Expansion Palette: Alt + P
Open the AI Prompt Menu: Alt + G (Ideally, select some text before hitting this shortcut).

Adding your API Key: To use the AI text generation features, go to the settings panel (gear icon) in either menu and input your Google Gemini API Key.

Technology

TypeScript: Typed logic and configuration.
Vite & vite-plugin-monkey: Fast builds tailored specifically for userscript compilation and GM_* APIs.
Native Web Components: The UI renders directly into the DOM using pure vanilla JS and strictly scoped CSS for maximum compatibility avoiding heavy framework overhead scenarios.
