OpenAI Translator (by yetone) is an open-source word/sentence translation tool that also polishes and summarizes text across 55 languages. It ships as a Chrome/Firefox browser extension and a Tauri-based desktop app for Windows, macOS, and Linux. It is fully BYOK: users paste their own API key into the settings UI and pick a provider. The source registers 14 provider engines (OpenAI, ChatGPT web, Azure OpenAI, Gemini, Claude, Groq, Moonshot, Kimi, MiniMax, ChatGLM, Cohere, DeepSeek, Cerebras, Ollama), and supports a configurable custom API endpoint / OpenAI API proxy for OpenAI-compatible backends. No hosted account or vendor key is required, the user supplies all credentials.

Why this trust score (69/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Transparency 20/20: Source is public under AGPL-3.0, so anyone can check how the key is handled.
