Ethertext

Ethertext is a macOS application that lives in your menu bar and acts as an AI-powered clipboard. You copy text from any application, select a transformation from Ethertext's menu, and then paste the AI-processed result. The tool can rewrite text in different tones, explain code, translate languages, and even memorize content for later recall. It works with text you copy, text you select and clean with a keyboard shortcut, or text from screenshots and voice dictation.

What makes Ethertext stand out is its flexibility in AI model selection. You can use cloud-based models from OpenAI, Google Gemini, or Anthropic Claude by providing your own API keys. For privacy-conscious users, it also supports local AI models through Ollama and Apple's on-device MLX framework, allowing text processing without sending data to external servers. The app includes a growing library of built-in prompts for common tasks like improving grammar, making text more formal, or adding creative flair.

This tool is particularly useful for anyone who frequently works with text on a Mac. Writers can quickly refine their prose, developers can get instant code explanations, and students or researchers can capture and summarize information from various sources. The ability to memorize web pages, documents, or voice notes and then ask questions about that content later makes Ethertext a practical tool for knowledge management alongside its core text transformation features.
