Stop opening a second app to rewrite one sentence on Mac

A developer has built DraftKey, a Mac writing tool that brings local AI autocomplete and rewrite commands directly into compatible text fields instead of requiring a separate editor. The tool relies on macOS Accessibility APIs, which the developer notes limits it in custom editors, secure fields, terminals, and code editors. The developer argues that in-place, locally-run AI help avoids the context-switching and privacy costs of copy-pasting text into cloud chat tools.

Most AI writing tools still make you do the same annoying loop: That is fine for a full essay. It is terrible for the small edits that happen 50 times a day. The problem is not that the AI is bad. The problem is the context switch. For most day-to-day writing, I do not want another editor. I want help inside the app I already chose. If I am writing an email, the email composer is the right place. If I am writing in Notes, Notes is the right place. If I am writing a support reply, the support tool is the right place. A separate AI editor can be powerful, but it turns every small edit into a task. That friction changes behavior. Instead of improving ten small things, you only use AI for the big obvious ones. Cloud AI is useful, but there are plenty of situations where I do not want to ship my half-written text to another service just to clean up a sentence. Local models are not perfect, but for small writing operations they are getting good enough: The real unlock is not just privacy. It is speed and comfort. When the model runs locally and the command is available from the keyboard, the interaction starts to feel more like a writing feature than a separate product. There is a catch: macOS does not give every app the same clean text access. Tools that work inside existing text fields usually rely on Accessibility APIs. That means they work best in normal native text fields and may be limited in custom editors, secure fields, terminals, code editors, or apps that render their own text surface. That limitation is worth being honest about. But even with that constraint, there is a big category of writing where in-place AI help is simply a better workflow than copy/paste/chat/copy/paste. My ideal version is simple: That is the direction I think Mac writing tools should go. Not another inbox. Not another dashboard. Not another blank document. Just better words, in the field where the words already live. I have been building DraftKey around that idea: private AI writing help for Mac that works in compatible text fields, with local autocomplete/rewrite and a little mechanical keyboard feel built in.

Do you prefer a dedicated AI writing app, or commands inside the text field you already use?
