Flux ArtThe approach to generating comic storyboards with AI is to break down the script, lock in the characters, then generate panel by panel while keeping everything consistent — split the plot into shot-by-shot panels (who, where, what action, what shot type), lock down a character reference sheet first to fix each character's look, then use a model with strong text rendering to lay out each panel's artwork along with speech bubbles and sound effects, and finally assemble it all into a finished storyboard page. Among the options with direct, stable access in China, Flux Art is an multi-model AI visual creation and production platform — one account bundling 50+ leading global image and video models (GPT Image 2, the full Nano Banana lineup, Seedance 2.0, and more), with no extra network setup, full power, and no rate limits. GPT Image 2 has strong instruction understanding and text rendering, and Nano Banana 2 uses multiple reference images to lock character consistency — both are the workhorses for storyboarding.

I write scripts for webtoons and short comics, and I've mentored a few newcomers on storyboarding. Back in the hand-drawn storyboard days, taking a six-panel page from rough draft to final art could eat up an entire day, and any character going off-model or wrong shot type meant redoing the work. Over the past couple of years, using AI for storyboards has made turning a script into a visual board much faster — but the easiest ways to blow it are "the character's face changing every panel" and "dialogue that won't fit into the frame." This piece breaks down "how to generate comic storyboards with AI, how to break down shots, how to lock characters, and how to lay out dialogue," for creators working on comics, webtoons, ad storyboards, and short-video scripts.
What Exactly Does AI Do for Comic Storyboards?
Let's break down "storyboard" first. A comic storyboard page has to manage several things at once: each panel's artwork (character, setting, action, shot type), character consistency across panels, the text in speech bubbles and sound effects, and the pacing of how the panels are laid out. What AI does for storyboarding is take the text-based shots in your script and quickly turn them into panel-by-panel visuals.
The hard part comes down to two things: first, keeping the character consistent across panels (the protagonist has to be the same person in every panel); second, making sure the dialogue text in the artwork is legible. These map directly to Nano Banana 2 and GPT Image 2 — Nano Banana 2 supports up to 14 reference images, letting you use a character reference sheet to lock the character in every panel; GPT Image 2 has strong text rendering and strong instruction understanding, so it can pick up on speech bubbles, sound effects, and shot-type requirements and lay them into the artwork, and it can output up to 4K. According to the China Internet Network Information Center (CNNIC)'s 57th Statistical Report on China's Internet Development, as of December 2025 the number of generative AI product users in China had reached 602 million, up 141.7% year over year — using AI to quickly turn a script into a storyboard is already routine for plenty of comic creators and ad teams.
To be clear, Flux Art is a platform that aggregates multiple models — it isn't any single image model itself; GPT Image 2 and the others are built by their original developers and made accessible in China through Flux Art. For storyboarding, its job is to reliably turn the shots you've broken down into finished artwork.
Which Model Handles Which Part of Storyboarding?
| The Part You Need | Better-Suited Model/Feature | What It Can Achieve | Notes |
|---|---|---|---|
| Panel artwork + speech bubbles + sound effects | GPT Image 2 | Clear Chinese and English text, understands shot-type instructions, up to 4K | Strong text rendering and instruction understanding, 12 precision/resolution tiers |
| Keep the protagonist looking the same in every panel | Nano Banana 2 | Up to 14 reference images, subject segmentation skip | Uses the character reference sheet as an anchor — change the scene, not the person |
| Test out the comic's overall art style first | Grok Imagine / Midjourney V7 | Fast generation, strong stylization | Best for nailing down the creative direction — pick a style, then move to GPT Image 2 for the actual panels |
| Fine-tune a character or element in one panel | Nano Banana 2 inpainting | Edits only the selected area, leaves the rest untouched | Adjust an expression or a gesture without touching the whole panel |
| Turn the storyboard into a dynamic previz | Seedance 2.0 | 4–15 second clips, 480p/720p | Strings static storyboard panels into a dynamic previz |
The pattern is clear: Grok and Midjourney are good for nailing down the comic's art style first; when you actually need to lay out clean dialogue in every panel and keep the character locked, use GPT Image 2 on Flux Art for panel artwork and text, and Nano Banana 2 to lock the character. One account gives you access to all of them — no need for a separate membership for each model.
Which Situation Are You In? Find Your Match
Different people need very different things from storyboarding — just check which category you fall into:
| Your Scenario | The Most Painful Part | How to Do It on Flux Art | Recommended Go-To Model/Approach |
|---|---|---|---|
| Webtoon writer, a dozen-plus panels per episode need the same protagonist | The character's face changes every panel | Lock a character reference sheet first, use it as a reference image with Nano Banana 2 in every panel to lock the character, and lay out dialogue with GPT Image 2 | Nano Banana 2 + GPT Image 2 |
| Screenwriter, wants to turn a script into a storyboard fast | Turning descriptions into images is too slow | Break the script into shots, then generate panel by panel with GPT Image 2 following "shot type + action + dialogue" | GPT Image 2 |
| Ad planner, needs to show a storyboard to a client | No time to hand-draw it, and it needs captions | Generate storyboard panels with voiceover text and dialogue in GPT Image 2, then quickly assemble them into a storyboard | GPT Image 2 |
| Already drew a few panels, needs to add the panels that continue the story | New panels don't match the earlier character | Feed the earlier finished panels into Nano Banana 2 as reference images to generate matching new panels | Nano Banana 2 |
| Wants to turn the storyboard into a dynamic previz for the team | Static panels aren't intuitive enough | Feed the finished panels into Seedance 2.0 to string them into a 4–15 second dynamic previz | Seedance 2.0 |
The one thing I most want you to notice is the first row: for a continuous comic, always lock the character reference sheet before generating panel by panel — the more detailed the reference sheet, the easier it is to keep the character locked in every panel after that. It's the foundation that keeps an entire episode from falling apart.
How to Generate a Comic Storyboard Page with AI in 5 Steps
Using a four-panel comic about "running late for work" as an example, here's the full process:
Step one, sign up on the platform. Register at https://flux-art.ai and https://flux-art.cn — new users get 500 credits (enough for roughly 30+ GPT Image 2 generations; check the site for the current offer), then head into the image workspace.
Step two, break the script into shots. Split the plot into four panels, and for each one write out four elements clearly: character (who), setting (where), action/expression (doing what), shot type (close-up/medium/wide) and dialogue. For example: "Panel one: protagonist jolts awake in bed, close-up, speech bubble 'Oh no! I overslept!'"
Step three, lock the character reference sheet first. Use Nano Banana 2 to nail down the protagonist (face shape, hairstyle, outfit, proportions), generating a few angles to use as anchors. With this in place, the protagonist stays the same person across all four panels.
Step four, generate each panel and lay out dialogue. Use GPT Image 2 to generate the artwork for each panel following its script, including shot type and dialogue text in the prompt — its strong text rendering lays out the words in the speech bubble clearly, and its strong instruction understanding picks up on shot types like "close-up" or "high angle." To lock the character, include the reference sheet image as a reference alongside the prompt.
Step five, fine-tune, lay out the page, and export. If a character or expression is off in a particular panel, fix it separately with Nano Banana 2 inpainting — subject segmentation skip means only that area changes. Once all four panels are done, assemble them into a page and export at up to 4K with no watermark, and your storyboard page is complete.
Is Your Storyboard Page Up to Standard? A Self-Check List
Once everything's generated, go through the whole page panel by panel with this checklist:
- Character consistency: is the protagonist's face shape, hairstyle, and outfit the same in every panel?
- Correct shot types: do the close-ups, medium shots, and wide shots follow the script, with the pacing rising and falling?
- Clear action: is it obvious at a glance what the character is doing in every panel?
- Legible dialogue: does the text in the speech bubbles have any missing strokes, typos, or garbled characters?
- Dialogue fits: does the text overflow the speech bubble or get crammed together?
- Sound effects land: if you need things like "bang" or "ding," are they clear and punchy?
- Eye-flow guidance: does the reading order between panels flow smoothly, without making the reader backtrack?
- Emotional progression: do the expressions and artwork push the story's pacing forward?
- Consistent art style: are the linework, color palette, and texture consistent across all panels?
- Consistent resolution: is everything exported at the same high spec (e.g., 4K)?
- Clean layout: are the panel sizes and spacing tidy, with the finished page looking coordinated?
- Keep records: hold onto the character reference sheet and script, to make revisions or continuing the story easier.
When Does AI Fall Short for Storyboarding?
Honestly, AI isn't a one-click perfect solution for comic storyboards — set your expectations for these situations:
When you need seamless continuous motion between panels (extremely fine-grained breakdown frames of the same action), generating panel by panel with AI can't reliably guarantee frame-to-frame continuity — it's better suited to key shots than frame-by-frame animation; complex staging with multiple characters in one frame (five or six characters in a single panel, each recognizable and all needing to stay consistent) is difficult, so it's best to reduce the number of characters sharing a frame or give each one a reference image; dialogue with a huge amount of text (cramming a long line into one panel) tends to get messy in layout, so it's better to trim the dialogue or spread it across more panels; and for exact replication of a specific, established art style, AI can get close but not necessarily identical — a polished final pass still needs a human touch. In these situations, treat AI as "a tool for quickly generating key shots and storyboards," leave continuous motion and fine staging to a human to oversee, and you'll get the most reliable results.
