TransFlow

Supports custom translation services and browser local translation

TransFlow is a flexible Chrome web translation extension that lets you read translations side-by-side while preserving the original webpage layout and interactivity. It supports full-page bilingual reading, text selection translation, and context-aware AI dictionary lookup, allowing you to freely choose between traditional translation engines, Chrome's built-in local AI, or your own custom LLM services. [Core Features] • Bilingual Page Translation: Translates web pages paragraph by paragraph, supporting both Bilingual Mode and Translation-Only Mode. • Original Layout Preservation: Keeps original DOM structure, links, inline code, and interactive elements intact. • Dynamic Content Tracking: Continuously translates dynamically loaded content, infinite scroll feeds, and expanded sections. • Text Selection Translation: Select any text on a page to quickly translate or look up words via a floating action button. • Context-Aware Dictionary Card: Displays context-specific definitions, phonetic symbols, parts of speech, inflections, and examples powered by AI models, with on-the-fly target language and model switching right inside the card. [Flexible Translation Engines & Custom LLMs] • Traditional Engines: Built-in support for Google Translate and Microsoft Translator out of the box. • Browser Built-in AI: Supports Chrome Translator and Chrome Prompt API (Gemini Nano) for private, on-device local translation. • LLM API Compatibility: Compatible with OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages protocols. • Custom Service Configuration: Configure custom API endpoints, API keys, model IDs, custom HTTP headers, and generation parameters. • Model & Connection Management: Fetch available model lists directly from your provider and test connection status with one click. • Prompt Management: Inspect built-in system prompts and create or switch between custom translation instructions. [Smart Workflow & Customization] • Auto-Translate & Navigation Continuity: Automatically translate new pages and keep translation active across page navigations and SPA route changes. • Site Rules: Manage "Always Translate" and "Never Translate (Disabled)" domain lists. • Floating Ball: Drag to reposition, click to toggle page translation, and optionally dock to the screen edge. • Custom Translation Styles: Choose from built-in visual presets or write custom CSS with a live preview. • Translation Cache: Local caching reduces redundant network requests and token usage, with one-click cache clearing. • Local File Support: Translate local HTML and text files (file:// URLs, when file URL access is enabled). • Multi-Language UI & Themes: Available in English, Simplified Chinese, Traditional Chinese, and Japanese, with Light, Dark, and System theme modes. Note: Browser built-in AI capabilities depend on Chrome API availability, device hardware, local model status, and supported language pairs.
