Local AI Writing Tool
Draft runs entirely on your Mac. Your text is processed locally using a powerful language model that never connects to the internet. No cloud. No servers. No data leaving your device.

Cloud-based AI tools like ChatGPT revolutionized how we work with text. But they came with a hidden cost: every word you type gets sent to someone else's server. For many professionals, that's a deal-breaker. Lawyers can't risk client confidentiality. Healthcare workers need HIPAA compliance. Companies have data governance policies. And plenty of people simply don't want a tech company reading their private thoughts.
Local AI solves this problem by running the language model directly on your computer. The technology that powers tools like ChatGPT — large language models — has been optimized to run efficiently on consumer hardware. Apple Silicon Macs, in particular, have powerful neural engines designed specifically for machine learning workloads. Draft takes advantage of this by running a compact but capable language model entirely on your device.
The result is AI writing assistance that's genuinely private. Not "we promise not to look at your data" private — but physically impossible for anyone else to access private. Your text stays in your computer's memory, processed by your hardware, and never transmitted anywhere.
The advantages of local processing

What you can do with Draft
Draft isn't trying to be a general-purpose AI assistant. It's a focused writing tool designed for one thing: making your text better. The workflow is simple — copy text from anywhere, open Draft with a keyboard shortcut, pick an action or write a custom instruction, then paste the result back.
The built-in actions cover the most common writing tasks: shortening verbose text, making writing more direct, simplifying complex language, adjusting tone for professional contexts, summarizing long content, converting prose to bullet points, and extracting action items from meeting notes. Each action is tuned to produce reliable, consistent results.
Beyond the presets, you can write any custom instruction. Tell Draft to "make this sound more friendly" or "rewrite for a technical audience" or "cut the marketing speak." The local model is capable enough to understand nuanced instructions while being fast enough for real-time editing workflows.
Is local AI good enough?
A fair question. Cloud AI services have access to massive models running on powerful server infrastructure. Can a local model really compete? For general knowledge questions and complex reasoning, probably not. But for writing tasks — editing, rewriting, summarizing, adjusting tone — a well-tuned local model performs remarkably well.
Draft uses a 4-billion parameter model specifically optimized for text editing. It's not trying to answer trivia questions or write code. It's trained to understand writing quality: what makes text clear, concise, and effective. For this specific task, it delivers results that are often indistinguishable from much larger models.
The tradeoff is worth it for many users. You give up some capability in exchange for complete privacy, offline access, and no ongoing subscription costs. If you primarily need help polishing your writing — not generating content from scratch — local AI is more than capable.
