How to Set Up Custom Writing Modes on iPhone

Create reusable writing modes that match your voice, tone, and structure. A step-by-step guide to building custom AI writing presets on iPhone.

Every writing situation calls for a different voice. A work update needs clarity and confidence. A message to a friend needs warmth. A client email needs professionalism without stiffness. Switching between these tones by hand is slow and inconsistent — you end up rewriting the same instruction every time.

Custom writing modes solve this. You define the voice, structure, and level of detail once, then apply it to any draft with a single tap. This guide shows how to build modes that actually work.

What a writing mode is

A writing mode is a saved instruction set that tells the AI how to rewrite your text. It includes the tone, the ideal sentence length, the level of formality, and any specific rules you want applied every time.

For example, a mode called “Team update” might say:

Write in a clear, direct voice. Keep sentences under 25 words. Use bullet points for action items. End with a single next-step question. Do not add greetings or sign-offs.

Once saved, every draft you rewrite with this mode follows the same pattern. No need to re-explain the task each time.

Step 1: Name the mode after the situation

The name should describe when you use it, not what it does. Good names: “Client follow-up,” “Meeting recap,” “Casual reply.” Weak names: “Professional mode” (too vague), “Mode 1” (you will forget).

If you cannot name the mode clearly, the situation is probably not repeatable enough to need a saved mode.

Step 2: Write clear, specific instructions

The AI follows instructions literally. Vague prompts produce vague results. Good instructions are:

  • Specific about tone — “Warm and encouraging” beats “friendly.”
  • Specific about structure — “Open with the main point, then add one sentence of context, then the ask” beats “structured.”
  • Specific about what to avoid — “Do not use exclamation marks” or “Do not start with I hope this finds you well.”

Here is a real example for a mode called “Quick decision”:

Write one short paragraph that states the decision needed, the two options, and the deadline. Do not add context or justification. Use plain language. Maximum 60 words.

Step 3: Test with real drafts

The first version of a mode almost always needs tweaking. Write three real drafts — an email, a message, a note — and rewrite each with the mode. Look for patterns in what the AI gets wrong.

Common fixes:

  • If the result is too long, add “Keep it under X words.”
  • If the tone is wrong, name the exact feeling: “confident, not aggressive.”
  • If the structure drifts, list the required parts in order.

Step 4: Save and use daily

In QKeyboard, modes live in the writing controls above the keyboard. Once saved, tap the mode name before rewriting — the AI applies your instructions to the draft.

The real benefit appears after a week of consistent use. You stop thinking about how to phrase things and start writing faster, knowing the mode will clean it up. The saved patterns become automatic.

When to create a new mode vs. reuse an existing one

Create a new mode when the situation has different rules. If you already have “Work update” but now need one for “Executive summary,” those are different — one is casual and action-oriented, the other is compact and high-level.

Tweaking an existing mode every time means the mode is not well-defined. If you find yourself wanting the mode to behave differently depending on the recipient, split it into two modes with clearer names.

Three modes worth building today

  • Decision request — Present the choice, the two options, and the deadline. One paragraph. No filler.
  • Meeting recap — Three bullet points: decision, action items, next meeting date. No narrative.
  • Soft no — Decline politely in two sentences. State the no, give a brief reason, and redirect if possible.

Build one mode today and use it for a week. Once you feel the rhythm, you will want custom modes for every writing pattern in your day.
