Let’s be real. AI copywriting isn’t new anymore.
If you’re in SaaS, you’ve likely been playing with ChatGPT, Claude, or another tool since 2022 or earlier. But by now, the novelty’s worn off, and what really matters is this:
Are you getting better content, faster—or are you wasting time fixing AI junk?
If you’re in the second camp, don’t worry. You’re not alone.
AI copywriting can save you hours, help you scale your content ops, and even improve your writing process. But only if you know how to prompt it well. That’s the difference between sounding like a robot and sounding like a brand customers trust.
Here are 10 of my best AI-powered SaaS copywriting tips to help you stop messing around and start producing content that actually converts.
1. Give it simple style instructions
One of the fastest ways to ruin your AI output? Giving it a mile-long prompt with overly specific style notes.
The more complicated your instructions, the more confused and clunky the writing gets. Instead, stick to this one-liner:
“The most important thing is for the content to be easy to read and personable. Our audience is small to medium businesses, so we don’t use jargon. But still write professionally.”
That’s it. That sentence alone consistently gives me cleaner, more natural content that doesn’t sound like it was scraped off the internet.
2. Write one section at a time
I never ask for a full blog post in one go. That’s how you end up with copy that sounds like a broken record.
Instead, I:
- Start with an outline
- Ask ChatGPT to write one section at a time
- Include a short direction like “this section should explain X in 90 words”
When you go section by section, you stay in control of voice, tone, and structure. The content also sounds way more human.
3. Assign word counts and structure
ChatGPT LOVES sameness. Every paragraph starts to look the same unless you tell it exactly what you want.
So be specific. For each section, include:
- A word count (ex: 90 words, 120 words)
- A format (ex: paragraph > bullet list > paragraph)
- Bullet point instructions (ex: unbold phrases only, no descriptions)
I rotate through four main formats to keep things fresh:
- Paragraph, bullet list, paragraph
- Long paragraph, bullet list, short wrap-up
- 2 intro sentences, bolded bullet list with short explanations
- No bullet points, just paragraph text
You’ll get much better results when you stop expecting the AI to do this on its own.
4. Feed it a writing sample
Want an instant tone upgrade? Give the AI a sample to mimic.
Here’s what I do:
- Paste in 120–150 words of on-brand copy
- Ask it to write the next section in the same style
This works especially well for brands that have a unique rhythm or sentence structure. You can even ask ChatGPT to analyze the sample and summarize the voice before writing.
Way more accurate than explaining the tone with adjectives.
5. Use AI to explore the competition
Here’s a clever research move: grab the outlines of 5–10 top-ranking posts from Frase or Surfer, paste them into ChatGPT, and ask:
“What are 2 topics these posts missed that we could cover?”
The AI is surprisingly good at identifying gaps. And those gaps? They’re your content edge.
6. Ask what’s missing
After you write a section, don’t move on right away. Instead, ask:
“What’s missing from this? What else would be helpful for the reader?”
It’s a small ask that can surface great ideas—like adding a stat, an example, or a key insight that deepens the content.
7. Spell out your house rules
If the brand you’re writing for has style quirks, make them clear.
For example:
- No dashes—use commas and periods
- Avoid “just” and “whether”
- Full sentences only, please
The more clearly you explain the rules, the fewer weird surprises in the output.
8. Add variety prompts
Sometimes, the AI writes fine. But it sounds like an AI.
Fix this by prompting: “Mix short and long sentences. Vary your paragraph length. Keep the tone casual but clear.”
Helps break up the monotony and makes your content more readable.
9. Save your best prompts
Start a prompt library. It’s one of the easiest ways to scale quality without burning yourself out.
Create a simple doc or Notion board where you collect what actually works. Every time you hit on a prompt that gives you a solid output, drop it in. Add a quick note on what it’s good for.
Include things like:
- Your best-performing voice/tone prompts
- Formatting setups (bullet list styles, word counts, paragraph layouts)
- Specific asks for SaaS feature pages, case studies, blog intros, etc.
- Prompts for rewriting, shortening, or making content sound more human
You can even organize them by brand, content type, or task.
This keeps your workflow fast and consistent. No guesswork. No backtracking. Just plug in the prompt and go.
10. Edit like you would with a junior writer
Don’t expect perfection. Even a great AI output is still a first draft.
I often follow up with:
- “Make it more casual”
- “Use simpler language”
- “Add a stat or example”
- “Cut the filler”
The more you treat the AI like a junior writer, the better your final product will be.
11. Always edit
ChatGPT doesn’t understand subtle tone adjustments. It’s usually a little too formal or it tries so hard to be informal that it’s obnoxious. This is why, no matter how good your prompts are, you always need to do some editing.
Take the time to read every line and add your personal touch.
This way, you don’t lose your unique tone of voice or perspective.
Especially if you’re a professional copywriter, clients come to you for a reason. Make sure you’re fulfilling those promises.
AI is an amazing tool. When you know how to guide it, refine it, and build processes around it, it becomes very effective.
