Fixkey

Fixkey is a native Mac writing assistant that rewrites, formats and translates selected text in any app, adds real-time dictation with a Voice Polish clean-up step, and lets users save custom prompts behind keyboard shortcuts. It targets Mac users who write across many apps and want corrections without leaving the window.

Fixkey is a native macOS writing assistant that sits above every application on the system and rewrites, polishes or translates text without requiring a browser tab or a copy-paste round trip. The product positions itself as a faster alternative to web-based grammar checkers, aimed at people who already know what they want to say and want the wording cleaned up inside the app where they are already working: Notion, Slack, Discord, WhatsApp, LinkedIn, Obsidian, Apple Notes, Signal and others named on the homepage. The two core paths are typing and speaking. On the text side, a keyboard shortcut sends the current selection through the AI, which can improve phrasing, restructure content into bullet points, or translate into more than 180 languages. On the voice side, real-time speech to text captures dictation anywhere on the Mac, and a Voice Polish step cleans up the transcription so the result reads as written prose. Voice commands handle formatting, so a user can dictate, apply structure and finish without touching the trackpad. Practically, the app leans on custom prompts. A prompt picker and prompt editor let a user save recurring instructions, such as a house tone for client emails or a shorter version for chat messages, then trigger them with configurable shortcuts. The homepage advertises response times under 200ms, which matters because the workflow depends on the tool feeling faster than fixing the sentence by hand. Users who write in a second language are an explicit target: translation and rewriting are presented as a way to sound sharp without native fluency. Fixkey competes with cross-platform grammar tools and with general chat assistants that require switching context. Its bet is that living inside the operating system beats living in a browser, and that voice plus text in one utility covers more of the day. The tradeoff is that the entire product is Mac-only, so teams with mixed devices cannot standardise on it.
