Texpander is a powerful, privacy-focused productivity tool that transforms the way you type on Android. By utilizing Android's Accessibility Services, Texpander monitors your custom abbreviation triggers in real time, instantly expanding them into full text phrases, invoking AI assistants, executing calculations, or running automated smart actions directly in any text field across your device.

CORE FEATURES
SMART TEXT EXPANSION (PHRASES & TEMPLATES)
• Custom Abbreviation Shortcuts: Instantly replace short triggers (like "/myaddr" or "@signature") with long blocks of text, multi-line emails, templates, or signatures.
• Dynamic Template Variables: Inject real-time contextual information like {date}, {time}, {clipboard} content, the active {app_name}, or the active chat recipient name ({sender}).
• Matching Precision: Set your shortcuts to be case-sensitive or case-insensitive, and toggle between instant expansions or trigger-on-delimiter (e.g., waiting for a double-space or punctuation).

ADVANCED AI WRITING ASSISTANT (PRO)
Inline AI Engine: Write prompts directly in your active typing field to ask the AI questions, summarize, or rephrase text.
• Configurable LLM Backends: Seamlessly configure your own API keys for Google Gemini or OpenRouter (supporting free models like ":free" or paid ones).
• AI Features: Enjoy smart capabilities like conversational contextual history, streaming word-by-word responses directly into your input fields, and AI memory.

REAL-TIME TRANSLATION ENGINE (PRO)
• On-the-fly Translations: Translate typed text instantly inside any messaging or social app.
• Auto-Language Detection: Automatically detects your source language and translates it into 18+ target languages (including Spanish, French, German, Chinese, Japanese, Arabic, Korean, and Hindi).
LOCAL UTILITIES & CALCULATORS (PRO)
• Live Math Solver: Evaluate math equations (e.g., "5 * 5 =") directly inside your text box.
• Currency & Unit Converter: Quickly convert metric/imperial values or switch between global currencies in real time.

NOTES & MEDIA VAULT (PRO)
• Text Snippet Storage: Access a dedicated vault inside the app to save notes and insert them using quick commands.
• Images Vault: Save, insert, copy, or view images straight from your database using keyboard shortcut expansions.

SYSTEM & UTILITY INJECTORS
• Location Injector: Automatically retrieve and paste your current device coordinates/location using simple trigger keywords. • Auto Alarms & Timers: Set device timers (e.g., "timer 10m study") or alarms (e.g., "alarm 07:30 Wake Up") directly from any typing field.
• Device Control Shortcuts: Launch frequently used apps or contact actions (make a phone call or search a contact) with quick shortcut abbreviations.
• Formatting Triggers: Apply markdown or text styles—including bold, italic, strikethrough, underline, reverse text, uppercase transformation, or sorting lists A-Z—with simple commands.

PRIVACY FIRST
• 100% Offline Processing: All core text expansion features, calculations, conversions, and vault storage are processed entirely locally on your device.
• Zero Data Harvesting: Texpander does not collect, store, transmit, or share any of your keystrokes, personal typing data, passwords, or messages.

ACCESSIBILITY SERVICE API DISCLOSURE Texpander requires enabling its Accessibility Service to function:
• Detection: It reads text input fields solely to detect when you type one of your predefined shortcut triggers.
• Expansion: When a trigger matches, it automatically replaces it with your saved phrase, note, or utility output.
• Security: The service never captures passwords, credit card numbers, or sensitive fields, and respects your privacy by processing everything locally.
