## What is FlashTranslate?

Flash Translate
Your Truly Private AI Translation Expert.

【Core Features】

Custom AI Models: Support for major AI models like OpenAI (GPT-4), DeepSeek, Claude, and more. By entering your own API Key, you have full control over translation quality and costs, enjoying cutting-edge AI technology. Flash Translate does not provide its own cloud model service; all translation capabilities are provided by the third-party AI service providers you configure.
Automatic Language Detection: Intelligently detects the language of input text and automatically selects the source language, eliminating the need for manual switching and making translation more convenient.
OCR Text Recognition: Extract text from images and translate it. Supports capturing photos or selecting images from your photo library. Recognized text can be directly translated in multiple styles, making translation easier for menus, signs, documents, and other scenarios.
Five Translation Styles:
Standard Translation: Precise and rigorous, suitable for daily communication.
Colloquial Style: More natural conversation, without "translationese."
Social Media: Captures the essence of popular expressions, making social interactions more interesting.
Business: Professional and appropriate, facilitating international workplace communication.
Academic: Carefully chosen words, conforming to academic expression standards.
Custom Prompts: Modify system prompts to customize the AI's translation persona and behavior logic according to your preferences.
Comprehensive Language Support: Supports translation between 17 major global languages:
Arabic, Dutch, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, Spanish, Thai, Turkish, Vietnamese, and Chinese.
Privacy & Security: Your API Keys and translation history are encrypted and stored only on your local device, never uploaded to our servers. Translation content is sent directly via HTTPS to the AI service provider you choose (such as OpenAI, DeepSeek, Anthropic, etc.), and we do not relay or store it additionally.
Lightning-Fast Experience: Card-based UI design with one-tap paste and copy, making translation as fast as a flash.
This app has no official partnership or affiliation with service providers like OpenAI, DeepSeek, Anthropic (Claude), etc., and serves only as a third-party client compatible with these services.

This app supports the following accessibility features:
VoiceOver: All interactive elements have clear accessibility labels
Dynamic Type: Supports system font size adjustment (from XS to accessibility XXL)
High Contrast: Uses system semantic colors, automatically adapting to high contrast mode
Dark Mode: Supports system dark/light theme switching
