Step-by-Step: How to Generate Line Art with Nano Banana

Here’s how you can try it yourself:

Open Google Gemini App or AISuperHub Nano Banana Image Generator

Step 1: Pick a Reference Image

Choose an image to transform into line art. It could be:

• A selfie or portrait photo.
• Your favorite anime or game character.
• An illustration or artwork you want reinterpreted.

Pro Tip: The clearer the subject, the cleaner the line art will be.

Step 2: Copy the Prompt

Use the exact viral prompt:

The Viral Line Art Prompt

Here’s the simple but powerful prompt that’s driving the trend:

draw a detailed beautiful portrait line drawing based on above image

At first glance, it may look too minimal. But don’t underestimate it, this combination of words is what gives Nano Banana enough instruction to deliver clear, aesthetic, and highly detailed line art results.

Let’s break it down:

• “draw” → sets the mode to illustration rather than photorealism.
• “detailed” → ensures the AI focuses on clarity and precision in the linework.
• “beautiful portrait” → makes the style visually appealing and centered on faces or figures.
• “line drawing” → locks in the style (thin black outlines, ink-like rendering).
• “based on above image” → tells Nano Banana to reinterpret your reference into a drawing.

The result: a portrait that looks hand-drawn but generated instantly.

You can paste this as-is or experiment with tweaks.

Step 3: Use the Nano Banana Free Generator

Head over to AISuperHub’s Nano Banana Free Image Generator.

Step 4: Customize for Different Effects

• Style tweaks

  • “minimalist portrait line drawing”
  • “comic book style line art”
  • “tattoo-style line drawing”

• Medium simulation

  • “ink pen line drawing”
  • “pencil sketch line art”
  • “engraving-style line drawing”

• Subjects

  • “draw a detailed line art portrait of a warrior character”
  • “line drawing of an anime couple”
  • “architectural building line art”

Step 5: Save & Share

Once you’ve generated the line art, download and share it. Many creators are using their results for:

• Social media profile pics.
• Tattoo inspiration.
• Comics or manga concept art.
• Personal keepsakes.

Why Nano Banana Excels at Line Art

Not every AI generator handles line drawings well. Many blur the edges or produce messy, inconsistent lines. Nano Banana, however, shines in this area because of how it interprets stylistic prompts.

Here’s why it works so well:

• Clarity of prompts: It locks onto “line drawing” as a defined style.
• Facial rendering: It handles human faces cleanly, avoiding distortion common in other AIs.
• Versatility: Works equally well for portraits, characters, and objects.
• Consistency: Repeated runs give results that look polished and professional.

Examples of Nano Banana Line Art

Here are some of the most popular uses we’ve seen trending online:

1. Anime Portraits
   Characters like Naruto, Luffy, and Goku transformed into clean line drawings perfect for manga-style posters.

2. Tattoo Concepts
   People are using Nano Banana to generate tattoo-ready designs without needing an illustrator.

3. Profile Pictures
   Minimalist line portraits stand out on social media because of their simplicity and elegance.

Pro Tips for Better Line Art Results

• Use high-contrast reference images: Makes it easier for the AI to define edges.
• Experiment with descriptors: Words like “minimalist,” “detailed,” or “ornamental” change the vibe.
• Keep faces clear: Obscured or low-quality images lead to messy results.
• Batch generate: Run the same prompt a few times—the best version often comes from iteration.

The Bigger Trend: Why Line Art Resonates Online

Line art is more than just a style—it’s a cultural aesthetic. Minimalist portraits and sketches are trending across Instagram, Pinterest, and Threads because they:

• Feel timeless and universal.
• Work well in both digital and printed formats.
• Can be used for fashion, tattoos, or branding.
• Are instantly recognizable at small sizes (like profile pictures).

That’s why the Nano Banana line art prompt is exploding right now—it fits right into what people want to share.
