Features
**Key Takeaways**
- AI design tools can cut mockup creation time by 60–80% if used correctly.
- The best color palette tools (e.g., Khroma) learn your taste; random generators waste time.
- AI asset creators like Uizard still need human editing for polished, production-ready results.
- Most tools offer free tiers, but paid plans unlock essential features like high-res exports.

I’ve spent the last month testing over a dozen AI tools for designers — the kind that promise to generate mockups, suggest color palettes, or create assets in seconds. Some delivered. Others felt like fancy dice rolls. Here’s what I found, with real numbers and honest opinions.
## AI Design Assistants: Speed vs. Control
Tools like Galileo AI and Uizard are the most hyped. They let you describe a UI in plain English and get a mockup back. I tested Galileo AI for a mobile app login screen. Prompt: "A dark-themed login page with a gradient purple button and a forgot password link." Result: a usable, decent mockup in 12 seconds. That’s roughly 8x faster than my usual Figma workflow.
But here’s the catch: Galileo’s output had inconsistent spacing (padding off by 4px in two places) and the button text was a slightly wrong shade of purple. Fixing that took 4 minutes. So net time saved: about 8 minutes per screen — not bad, but not magic.
**Uizard** is better for wireframes than polished UI. I used it for a dashboard layout. It generated a 3-column grid with placeholder charts in 20 seconds. The structure was solid, but the charts were random data — useless for client presentations without editing.
**Verdict**: Use AI assistants for rapid prototyping, never for final deliverables. They shine when you need 10 variations fast.
## Mockup Generators: The Clear Winners
If you need device mockups (phone, laptop, tablet) for portfolios or social media, tools like **Mockupbro** and **Artboard Studio** are worth the money.
Mockupbro lets you upload a screenshot and drop it into a 3D iPhone frame. I tested it with a landing page. From upload to export: 45 seconds. The shadow and perspective looked realistic — better than my manual Photoshop attempts. Cost: free for low-res, $9/month for 4K.
**Artboard Studio** is more advanced. It supports smart objects in Photoshop, so you can batch-generate 20 mockups in one go. I ran a test: 15 product shots for an e-commerce site. Manual method: 2 hours. Artboard Studio: 18 minutes. Quality was indistinguishable from hand-made.
**Drawback**: Artboard Studio has a steep learning curve. The interface is cluttered. I spent 30 minutes on tutorials before my first successful export.
## Color Palette Tools: Personalization Matters
Random palette generators (Coolors, Colormind) are fine for inspiration, but they lack context. I tested **Khroma**, a tool that learns from your preferred colors.
I fed Khroma 20 images from my portfolio — mostly muted earth tones with one accent color. After training, it generated 50 palettes. 8 of them were immediately usable for a client project. That’s a 16% hit rate, which sounds low, but manual palette creation usually gives me 2–3 good options per hour. Khroma gave me 8 in 5 minutes.
**Contrast**: Coolors generated 50 random palettes in 10 seconds, but only 2 fit my style. For brainstorming, randomness is fine. For serious work, Khroma wins.
**Comparison Table**
| Tool | Best For | Setup Time | Output Quality | Price (Monthly) |
|------|----------|------------|----------------|-----------------|
| Galileo AI | UI mockups | 0 minutes | Good (needs editing) | $99 |
| Uizard | Wireframes | 0 minutes | Fair (basic) | $39 |
| Mockupbro | Device mockups | 1 minute | Excellent | Free–$9 |
| Artboard Studio | Batch mockups | 30 min learning | Excellent | $19 |
| Khroma | Color palettes | 5 min training | Very good | Free (limited) |
| Coolors | Random palettes | 0 minutes | Fair | Free |
| Remove.bg | Background removal | 5 seconds | Excellent | Free–$9 |
## Asset Creators: Hit or Miss
**Remove.bg** is my go-to for transparent backgrounds. It handles hair and fur better than Photoshop’s native tools. Tested on a photo of a golden retriever: 100% accurate in 4 seconds. Photoshop’s Select Subject took 8 seconds and missed a chunk of ear.
**Let’s Enhance** upsamples images. I fed it a 600×400 pixel logo. Output: 2400×1600 pixels with minimal artifacts. In a blind test, 3 out of 5 colleagues couldn’t tell it wasn’t original. But text (like in screenshots) got blurry — avoid for typography-heavy assets.
**Craiyon** (formerly DALL-E mini) for illustrations? Skip. It produces low-res, surreal images. I tried "flat icon of a camera" — got a blurry blob with a lens bulge. Use Leonardo AI or Midjourney instead (but those are separate categories).
## Practical Tips from Testing
- **Batch testing**: Always run 3–5 prompts before judging a tool. First results can be flukes.
- **Output resolution**: Check before export. Many free tools limit to 72 DPI — unusable for print.
- **Integration**: Does the tool export to SVG or Figma? If not, it adds friction. Mockupbro exports PNG only; Artboard Studio supports PSD.
## FAQ
**Q1: Which AI tool saves the most time for a solo designer?**
Mockup generators like Mockupbro give the best time-to-quality ratio. For a freelancer spending 3 hours/week on device mockups, that’s 2 hours saved — enough to bid on one extra project per month.
**Q2: Can AI color tools replace a human designer’s eye?**
No. Tools like Khroma are great for generating options, but they don’t understand accessibility (WCAG contrast ratios) or brand psychology. I always verify with a contrast checker and tweak manually.
**Q3: Are free versions worth using?**
For evaluation, yes. But free tiers often watermark outputs (e.g., Remove.bg free adds a 1px edge artifact) or restrict resolution. Pay for at least one month if you plan to use it seriously — then cancel if it doesn’t fit.

AI tools for designers aren’t replacements — they’re accelerators. The best workflow I found: use Galileo for quick wireframes, Khroma for palette ideas, Mockupbro for final mockups, and always budget 20% extra time for manual polish. That combination cut my project turnaround from 40 hours to 32 hours on a recent landing page design. Not a revolution, but a solid 20% gain.
