If you’ve ever stared at a blank screen trying to sum up your SaaS product, you know it’s harder than it looks. Writing product descriptions that actually get people interested—without sounding like a robot or a hype machine—is a skill. Thankfully, AI tools like Writesonic can help, but only if you know how to use them right. This guide breaks down how to craft effective, honest SaaS product descriptions using Writesonic—what works, what’s a waste of time, and how to get the most out of the tool.
Why Product Descriptions Matter (and Why Most Suck)
Let’s be real. Most SaaS product descriptions are either a jargon soup (“next-gen, cloud-native synergy!”) or a snoozefest that could describe any tool on the market. If you want people to actually try your product, your description needs to:
- Say what it does in plain English
- Show how it’s different (without bragging)
- Help the reader picture themselves using it
- Not overpromise or sound like a scam
Good descriptions build trust. Bad ones drive people away—or worse, set them up for disappointment.
Step 1: Get Your Basics Straight Before Touching AI
Before you even open Writesonic or any other AI tool, nail down the essentials. AI is only as good as your input.
What you need to know:
- Who’s the user? Be specific. “SMB owners” isn’t enough. Try “time-strapped marketing managers at B2B startups.”
- What problem does your SaaS solve? Seriously—write it out in one sentence. If you can’t, AI won’t be able to either.
- What makes you different? If it’s “better UX” or “cheaper,” get more concrete. Do you integrate with a tool nobody else does? Is your onboarding under 5 minutes?
- What’s your tone? Friendly? Expert? Irreverent? Decide, or you’ll get generic mush.
Pro tip: Jot down your answers in a doc. You’ll use these in your prompts, and it’ll keep you (and the AI) from drifting into nonsense.
Step 2: Set Up Writesonic for the Task
Once your basics are clear, it’s time to fire up Writesonic. Don’t just pick the first template you see—take a minute to explore what fits.
How to pick the right tool:
- Product Description Template: Good for short, punchy blurbs (think app stores, landing pages).
- Landing Page Generator: If you need a longer description with sections and benefits.
- Feature-to-Benefit Tool: Useful if you have a laundry list of features but need to translate them into something people care about.
What to skip: Tools labeled “SEO Description” or “Meta Description” aren’t for humans—they’re for Google. They’re fine for metadata, but not for convincing real people.
Honest take: The templates make it easy, but the output is only as strong as what you put in. Don’t expect magic from one-line prompts.
Step 3: Crafting a Prompt That Doesn’t Suck
AI tools aren’t mind readers. The more detail you give, the better the results.
What to include in your prompt:
- The basics: Product name, audience, what it does
- Key differentiators: Be specific, not fluffy
- Any “must-have” phrases or words
- Desired tone: (e.g., “conversational and honest, avoid buzzwords”)
Example of a weak prompt:
“Write a product description for a SaaS time-tracking tool.”
Example of a strong prompt:
“Write a 2-3 sentence product description for Clockwise, a SaaS time-tracking app for remote marketing teams at startups. Highlight that it integrates directly with Slack and Google Calendar, and can be set up in under 2 minutes. Use a friendly, straightforward tone—avoid buzzwords and hype.”
Pro tip: If you’re embarrassed to show your prompt to a coworker, it’s probably too vague.
Step 4: Reviewing Writesonic’s Output—What to Keep, What to Ignore
AI-generated copy is like a first draft from an intern: promising, but it needs your eye.
What AI gets right:
- Quick, clear summaries
- Pulling benefit statements from your input
- Basic structure and flow
What to watch out for:
- Repeating buzzwords: “Seamless,” “cutting-edge,” etc. The AI loves these. Swap them out or cut them entirely.
- Vagueness: If a sentence could apply to any SaaS, delete it.
- Overpromising: AI sometimes claims things you haven’t told it. Don’t let it make promises your product can’t keep.
- Tone drift: AI can sound stilted or too “salesy.” Edit to match your brand voice.
Checklist for editing: - Is it clear what the product does, in the first sentence? - Does it mention who it’s for? - Are the benefits concrete, not generic? - Is there any claim that’s not true or not provable? Cut it.
Pro tip: Read it out loud. If it feels awkward or makes you cringe, rewrite it.
Step 5: Polish and Make It Yours
Don’t just copy-paste AI output. Take the best bits, then add your human touch.
How to improve the draft:
- Cut filler: Shorter is usually better.
- Add personality: A little humor or empathy goes a long way, as long as it’s real.
- Use specifics: Numbers, examples, and details are gold. (“Onboards in 90 seconds” beats “fast onboarding.”)
- Check for clarity: Would your non-techie friend get it? If not, simplify.
What not to worry about: Don’t fuss over SEO keywords here—focus on clarity and honesty. You can tweak for SEO elsewhere.
Step 6: Test, Iterate, and Get Real Feedback
No copy is perfect out of the gate. Before you ship it:
- Show it to someone who’s never heard of your product. Ask: “Do you get what it does? Would you try it?”
- If you have users, ask them what made them sign up. Borrow their language.
- Swap out a line or two and see if conversions change—don’t be precious.
Pro tip: Save your prompts and edits. Next time you need a description, you’ll have a head start.
What to Ignore (Most of the Time)
- Hype about “AI writing everything for you.” It won’t. You still need to think.
- Chasing every new template. Most are just variations on the same thing.
- Obsessing over length. Say what matters, then stop. Don’t pad to hit a word count.
Keep It Simple—And Keep Improving
Effective SaaS product descriptions don’t need to be clever or packed with buzzwords. They just need to be clear, honest, and easy to read. AI tools like Writesonic can save you time, but they’re not a replacement for your judgment. Stick to what works, keep tweaking, and don’t overthink it. The best copy is the one that helps real people understand—and try—what you’ve built.
