Writers Brew: Affordable AI Writing Assistant for macOS

Writers Brew is a native macOS AI writing companion built to slot into your existing workflow rather than force you into a new one. Because it runs on your own OpenAI API key, it delivers the same GPT-3.5, GPT-4, and GPT-4o power as premium writing tools like Jasper or CopyAI, but at a fraction of the cost—reportedly 10x to 100x cheaper. It works system-wide across browsers, native macOS apps, and Electron apps, so you never have to switch context to get writing help. Beyond core AI prompts for rewriting, summarizing, explaining, replying, and translating text, Writers Brew bundles handy non-AI utilities, text snippets for repetitive typing, and an OCR-to-text feature that pulls text straight out of images. Power users can go further with BYOP (Build Your Own Presets), crafting custom prompts tailored to their exact workflow, and connecting the app to Raycast or PopClip for even faster access. Whether you're polishing an essay, drafting a social post, replying to messages, or digesting a dense research article, Writers Brew aims to be the quiet, always-available assistant sitting in your menu bar—ready the moment you highlight text and hit a shortcut.

Install Writers Brew on macOS 14.0 or later and connect your own OpenAI API key. Access the tool via Spotlight search, the menu bar icon, the full app window, or global keyboard shortcuts. To use it, simply highlight any text in any app, trigger your chosen shortcut, and select an AI prompt, utility, translation, or custom preset. Results are applied instantly, without needing to copy-paste into a separate browser tab or app.
