NextAI Translator (formerly OpenAI Translator, renamed after an OpenAI trademark warning) is an open-source, cross-platform translation tool that started as a Bob/Chrome plugin and grew into a browser extension (Chrome, Firefox) plus desktop apps for Windows, macOS, and Linux. It offers three modes (translate, polish, summarize) across 55 languages, with streaming responses, text-to-speech, screenshot/OCR translation, vocabulary book, and clip-extension integrations. Users bring their own provider API keys, configured in the settings UI. The repo ships dedicated engine implementations for a wide range of providers and confirmed OpenAI-compatible custom-endpoint support (used for local servers like Ollama and LM Studio, and providers such as MiniMax). It is AGPL-3.0 licensed, has ~24.9k GitHub stars, and is actively maintained (v0.6.20 released June 2026).
How your API key is handled
Your API key is stored in your browser's local storage. Requests are sent directly to the AI provider.
Setup
Open the extension/app settings, paste your provider API key (kept in your browser), and pick a model.
