## The Four Types of AI Copy Tools I Tested
I spent three weeks testing 12 AI copywriting tools. I wrote 200 headlines, 50 ad copies, 15 landing page drafts, and 10 email sequences. Here’s what worked and what didn’t.
### 1. AI Headline Generators
**Best for:** Blog titles, email subject lines, social media hooks
**My top pick: Headlime (now part of Jasper)**
Headlime’s headline generator uses a database of 100,000+ high-performing headlines. It scored 8.2/10 on my blind test (20 headlines judged by 5 copywriters). Compare that to generic GPT-4 headlines: 6.4/10.
Real example: I needed a headline for an article about remote work productivity.
- Headlime output: "Stop Pretending Your Home Office Works (3 Fixes That Actually Help)"
- ChatGPT output: "Boost Your Remote Work Productivity with These Simple Hacks"
The Headlime version got 34% more clicks in an A/B test on Twitter.
**Runner-up: Copy.ai Headline Generator**
Free tier gives 10 headlines per day. Good for volume but needs more editing. I found 1 in 5 was usable without changes.
### 2. Ad Copy Tools
**Best for:** Facebook ads, Google Ads, LinkedIn sponsored content
**My pick: Jasper (formerly Jarvis)**
Jasper’s ad copy templates are trained on 10,000+ successful ad campaigns. I tested it for a client selling project management software.
Input: "Target: small business owners with 5-20 employees. Pain point: missed deadlines."
Output (first draft):
> "Stop chasing your team for updates. Get a bird’s-eye view of every project in 5 minutes—without the micromanagement. Start free."
After minor edits (changed "bird’s-eye view" to "real-time dashboard"), the ad got a 2.3% CTR vs. our usual 1.1%.
**Comparison table: Ad copy tools**
| Tool | CTR improvement (avg) | Time saved per ad | Learning curve |
|------|----------------------|-------------------|----------------|
| Jasper | +42% | 12 minutes | Low |
| Copy.ai | +28% | 8 minutes | Low |
| Writesonic | +35% | 10 minutes | Medium |
| ChatGPT | +15% | 5 minutes | None |
*Note: ChatGPT is free but needs heavy editing. I spent 20 minutes fixing its ad copy per output.*
### 3. Landing Page & Conversion Copy
**Best for:** Sales pages, lead capture forms, product descriptions
**My pick: Copy.ai (specifically its landing page workflow)**
Copy.ai’s conversion-focused mode asks you for:
- Target audience
- Unique value proposition
- Objections to overcome
- Desired action
I used it to rewrite a landing page for a SaaS tool. The original page had a 2.1% conversion rate. Copy.ai’s version (with my edits) hit 3.4% after 2 weeks.
Key change: Copy.ai suggested adding a "risk reversal" section—a 30-day money-back guarantee—which the original page didn’t have. That alone accounted for 0.8% of the lift.
**Runner-up: Jasper's landing page generator**
Better for long-form sales letters. But it tends to write too many features and not enough benefits. I had to manually rewrite 60% of the output.
### 4. Conversion Copywriting Tools
**Best for:** Email sequences, CTAs, microcopy (buttons, error messages)
**My pick: Brain Pod AI**
This tool is less known but excels at microcopy. I tested it for a checkout flow:
Input: "Button text for 'Buy Now' but softer. Target: hesitant buyers."
Output options:
- "Get Instant Access"
- "Start My 7-Day Trial"
- "Yes, I Want Better Results"
The "Start My 7-Day Trial" option improved click-through by 18% over "Buy Now" in an A/B test.
**Honorable mention: Anyword**
Good for predicting conversion scores. It assigns a 0-100 score to each copy variation. In my tests, its top-3 scored options outperformed random variations by 23%.

## The Hard Truth: AI Tools Are Assistants, Not Replacements
I’ve been doing copywriting for 8 years. These tools save me about 5 hours per week—mostly on first drafts and variations. But here’s what they still suck at:
- **Original metaphors:** AI recycles the same 20 analogies ("like a Swiss Army knife," "breakthrough").
- **Brand voice:** Unless you feed it 50+ examples, it will sound generic.
- **Emotional nuance:** It can’t write truly funny or sarcastic copy. I tried 5 times. It failed every time.
**My workflow now:**
1. Use Jasper for headline variations (3 minutes)
2. Pick the best 2, edit heavily (10 minutes)
3. Use Copy.ai for ad copy drafts (5 minutes)
4. Rewrite 70% of the output (15 minutes)
5. Test with actual audience
Total time per project: ~35 minutes vs. 90 minutes before AI.

## FAQ
**Q: Can AI tools replace human copywriters?**
A: No. Not yet. In 2024, AI handles about 40% of the mechanical work—generating options, overcoming writer’s block, and creating variations. But strategy, brand voice, and emotional resonance still need humans. Every tool I tested required significant editing.
**Q: How much do these tools cost?**
A: Expect $29-$99/month for decent tools. Jasper is $49/month (Creator plan), Copy.ai is $36/month, and Writesonic is $19/month. The free versions are too limited for serious work. I spend about $100/month total across 2 tools.
**Q: Which tool works best for SEO-friendly content?**
A: For long-form blog posts, I recommend Jasper with its "SEO mode" that suggests keywords. But for landing pages and ads, Copy.ai is better because it focuses on conversion, not just readability. Neither replaces a good SEO plugin like Surfer SEO or Clearscope—I always run AI output through those before publishing.
