The Four Pillars of Good Writing
Clarity
Your reader should never have to re-read a sentence to understand it. Use plain language, short sentences, and familiar words.
Conciseness
Say what you need to say and stop. Remove filler words like very, really, actually, and just.
Structure
Organize your writing so the main point comes first. Use headings, short paragraphs, and bullet points to guide the reader.
Tone
Match your tone to your audience. Professional for work, friendly for coworkers, warm for customer communication.
Mastering Mobile AI: Prompt Engineering
Good writing applies to how you instruct AI, too. When you use an advanced keyboard extension, writing custom instructions turns the AI into a precise assistant that mirrors your true intent.
The Problem with Rigid Buttons
Standard mobile presets like “Make Professional” or “Casual” strip away context, often producing dry, generic fluff that sounds robotic.
The Power of Custom Instructions
Editable prompts give you total control. Specify the details:“Shorten this email, make it warm, and do not apologize.”
Fixed Presets vs. Custom Commands
Saying "No" to a Client
Drafting a Quick Slack Update
The Writing Process
1. Plan
Know your audience and your goal before you write. What do you want the reader to know, feel, or do?
2. Draft
Write without editing. Get your ideas down first. Don't worry about perfection — you will fix it in the next step.
3. Revise
Read your draft aloud. Cut unnecessary words. Check that your argument flows logically.
4. Edit
Fix grammar, spelling, and punctuation. Use a grammar checker to catch what you missed.
Common Writing Weaknesses

After: If the meeting is cancelled, we will notify you.
Jargon

After: We should use our strengths.
