What is better-write?

Better Write is an extension for Raycast, a keyboard driven launcher that lets you trigger commands from anywhere on your computer, that rewrites whatever text you have selected using an AI language model. Instead of copying text into a separate chat window, you highlight it in any app, run one of the extension's commands, and the rewritten version replaces your selection in place with no extra confirmation step. The extension offers five commands, each of which can get its own keyboard shortcut in Raycast: Fix Grammar corrects grammar, spelling, and punctuation while keeping your voice, Rephrase rewrites for clarity at roughly the same length, Make Friendly gives text a warmer, more conversational tone, Make Professional makes it sound clean and business appropriate, and Expand adds more detail and improves clarity. All five are thin wrappers around one shared workflow that grabs the current selection, sends it to the configured model, and pastes the result back. Under the hood, the extension talks to any model provider that supports the OpenAI style chat completions API, and you bring your own API key. The README lists OpenAI, OpenRouter, Groq, DeepSeek, and an OpenAI compatible Anthropic endpoint as supported cloud providers, plus local options like Ollama and LM Studio for anyone who wants to run a model entirely on their own machine with nothing sent anywhere else. Setup means installing the extension, opening its preferences in Raycast, and filling in the API key, base URL, and model name for your chosen provider, with the option to customize the system prompt behind each command. The code is written in TypeScript. According to the README, your selected text is sent only to whichever provider you configure and nothing is logged elsewhere. The project is released under the MIT license.
