Simple tweaks for faster responses, lower costs, and clearer thinking in every AI conversation.
Written by Pax Koi, creator of Plainkoi — tools and essays for clear thinking in the age of AI.
In a world where every word you send to an AI might soon come with a price tag, prompting well isn’t just a productivity flex—it’s a survival skill.
The good news? Most of what wastes tokens also wastes your time, focus, and patience. So whether you’re trying to save money or just your own sanity, these 10 prompt habits will help you get more from less.
Let’s trim the fat and sharpen the signal.
1. Start with the End in Mind
Before you type, ask: What do I actually want from this?
Vague input leads to vague output—which leads to more prompting. If you can’t define your goal, the AI won’t hit it either.
Example:
Instead of: “Tell me about productivity.”
Try: “Give me 5 unconventional productivity tips for solo remote workers.”
Clear goal = fewer retries.
2. Don’t Bury the Lead
AI models read top-down. Don’t make them dig.
Put your key instruction first, then context if needed.
Think: headline first, backstory later.
Instead of:
“I’m working on a blog post about attention spans, and I’ve been thinking about how technology…”
Try:
“Summarize the pros and cons of short-form content for readers with limited attention spans.”
Start sharp.
3. Skip the Fluff
AI doesn’t need small talk. Every word burns a token.
You can be polite and efficient.
Skip “Hey buddy, hope you’re doing well. I was just wondering if you could maybe…” and go straight to the task.
Instead of:
“Hi! Quick question for you. I was thinking about writing something…”
Try:
“Write a 300-word blog intro on how to stay focused when working from home.”
Be kind, but cut the filler.
4. Give it a Shape
The clearer the format, the better the output.
Say what you want:
“List of 5 bullet points”
“Table with pros and cons”
“Twitter thread format”
“Two-paragraph summary”
Structure gives the AI constraints. Constraints reduce rambling. Rambling burns tokens.
5. Stop Repeating Yourself (Unless You Mean To)
AI models remember the context of your message. Repeating your request usually doesn’t help—it just adds to the token count.
If you don’t get what you need, refine or clarify. Don’t just restate.
Bad:
“Can you do that again but better?”
“Can you try that again?”
“Can you do that again with more details?”
Better:
“Try again, but with a warmer tone and shorter sentences.”
Precision > repetition.
6. Use Examples to Lock in Style
If you want a specific voice, tone, or structure—show it.
Example:
“Write this in the style of a newsletter opener, like this: ‘Ever had one of those days where your brain feels like a browser with 100 tabs open?’”
One example can do more than three paragraphs of explanation.
Think of it as showing, not telling—for machines.
7. Trim the Prompt Fat Before You Hit Send
Before you click “Submit,” ask:
Is every part of this prompt helping the AI respond better?
If not, cut it.
That wandering backstory? The rhetorical question? The “I’m just thinking out loud…” section? Probably not needed.
The tighter your ask, the tighter your answer.
8. Use Follow-Ups Like a Surgeon, Not a Sledgehammer
Follow-up prompts are powerful—but don’t fall into the spiral of “fixing” with increasingly bloated messages.
Instead of:
“Ok, now do it again but this time maybe make it a little bit more conversational and also shorter and maybe use some examples but not too many…”
Try:
“Same response, but make it more conversational and cut it by 40%.”
Clean edits. Surgical changes.
9. Choose the Right Model for the Job
Not every task needs GPT-4o or Claude Opus.
Lightweight models (like GPT-3.5 or Claude Instant) are cheaper and faster—and perfectly fine for summaries, outlines, drafts, or simple Q&A.
Save the big models for when you really need their reasoning or nuance. You wouldn’t use a blowtorch to light a candle.
10. Don’t Be Afraid to Reuse Winning Prompts
Found a prompt that works? Save it.
Make a little library. Build templates. Reuse them like macros.
You don’t need to reinvent the wheel for every interaction. Efficiency isn’t just about writing less—it’s about writing once, then using smartly.
Final Thought: Your Brain Is the Cheapest Model You Have
Prompting well isn’t about being clever. It’s about being clear. And clarity always starts in your own thinking.
If you can articulate the outcome you want, trim the fat, and structure your ask, you’ll not only save tokens—you’ll get better, faster, and saner results every time.
The models may evolve. The pricing may change. But clarity?
That’s always free.
If your prompts sometimes land flat, confuse the AI, or feel slightly off—this isn’t about “fixing the tool.” It’s about clarifying the signal you’re sending. Checkout our free prompt coherence kit: https://www.aipromptcoherence.com/p/ai-prompt-coherence-kit.html
