# ScribeAI > ScribeAI is a free, open-source, offline AI writing assistant for macOS. Select text in any app, press Option-Command-S, and it rewrites the text locally with an on-device WebGPU model — no server, no account, no upload. MIT licensed. The current release is v1.0.1. ScribeAI runs entirely on Apple silicon Macs (macOS 12 or later, 8GB+ memory). The default model is a 4-bit quantized Qwen2.5-1.5B-Instruct served by MLC WebLLM at ~1.6GB peak VRAM, downloaded once (~390MB) and cached on device. Users may optionally add their own Gemini or OpenAI API key to route rewrites through a cloud model instead; that mode requires internet. The global hotkey is Option-Command-S, driven by a macOS accessibility agent. ## Product - [Homepage](https://scribeai.shop/): landing page with feature list, specs, install steps, and FAQ - [Download for macOS](https://github.com/Anirudh3434/scribeai/releases/latest): direct link to the latest GitHub release (DMG, Apple silicon) - [All releases](https://github.com/Anirudh3434/scribeai/releases): version history and release notes - [Source code](https://github.com/Anirudh3434/scribeai): public GitHub repository, MIT licence ## Privacy & terms - [Privacy policy](https://scribeai.shop/privacy.html): what is and is not collected - [Terms of service](https://scribeai.shop/terms.html): conditions of use ## Pricing ScribeAI is free.
