TransKit - Power Inline Translate Kit

Tracking since Apr 1, 2026.

Changelog

• Apr 11, 2026
  description

  TransKit is a Chrome extension that brings instant, AI-powered translation directly to your input fields. No more switching tabs or copy-pasting - just type, command, and translate.
  
  What's new in v1.2.2?
  
  Enhanced Text-to-Speech (TTS)
  
  • New TTS Configuration Tab: A dedicated tab in the popup allows you to manage TTS providers.
  • Custom TTS Providers: You can now add your own TTS services using custom URL templates, giving you more flexibility beyond the default Google TTS.
  • Improved UI: The speaker icon now features a modern sound wave animation during playback, replacing the previous spinner.
  • New: Line-by-Line Translation - Default granularity changed from "block" to "line" for more precise hover translations.
  • New: Smart Boundary Detection - Intelligent detection of message boundaries on chat platforms (Discord, Slack, Telegram). No more accidentally selecting entire conversations.
  
  CORE FEATURES
  
  • Inline Translation
  Select any text - in inputs, text areas, or anywhere on the page - and translate instantly without leaving your workflow. TransKit understands code syntax, preserves formatting, and translates context-aware.
  
  • Domain-Aware Translation
  Configure which domains auto-translate. Visit docs.ic.org, GitHub, or any documentation? TransKit remembers and translates automatically. No manual work, just smart defaults.
  
  • Offline-First
  Translate for free using Chrome's built-in AI (window.ai). No API key needed. 
  No internet? No problem. Works completely offline.
  
  • Privacy-Focused
  Open source. No tracking. Your data stays on your device. We don't log, store, or sell your translations.
  
  • Optional API Integration
  Need higher quality? Upgrade to Gemini, OpenAI, or your preferred API for production-grade translations. Your choice, your cost.
  
  • 100+ Languages
  Supports every major language pair. English ↔ Vietnamese, English ↔ Spanish, and 100+ others.
