Most AI writing workflows begin with copy and paste. You copy text from Slack or Mail, open a chat, explain the job, copy the answer, and return to the original app.
That is fine for occasional work. It gets annoying when the prompt is something you use every day.
A reusable writing action has three parts:
That is the pattern behind Type Mac, a native macOS app I work on. The instruction can be simple, such as "fix grammar without changing my meaning," or specific to a role.
A few useful examples:
The important part is not the model. It is removing a repeated decision from the workflow.
Broad prompts tend to produce broad rewrites. A good shortcut should solve one familiar job and make its boundaries clear.
For grammar fixes, tell it to preserve meaning and length. For Slack, ask for short sentences and no formal greeting. For customer replies, define the tone and any facts that must remain unchanged.
Type Mac can use its ready-to-go model, or you can connect OpenAI, Anthropic, Gemini, Groq, or OpenRouter. Bring-your-own provider keys are stored in macOS Keychain.
Apple Writing Tools is a solid built-in choice on compatible Macs. Grammarly is useful if you want suggestions and explanations while you type. This shortcut-first approach is for people who prefer to finish a thought, run one deliberate action, and continue working.
I work on Type Mac, so this is a transparent product perspective. If you want to try the workflow, Type Mac has a seven-day free trial and does not require a card.
