Make a Four-Panel Comic on Your Phone, No App or Drawing Skills

You'd like to make a four-panel comic strip (what Japan calls "4koma"), but you have no PC, no drawing tablet and not much confidence in your drawing. You can still make one from your phone's browser by typing a single line. This guide uses BunCho's Quick Create to walk from picking a premise to saving an image ready to post. No app install needed.
Think in four beats: setup, build, twist, payoff
The classic four-panel strip shows the situation in panel 1, develops it in panel 2, flips it in panel 3 and lands the punchline in panel 4. Many strips that do well on social media open with a situation readers instantly recognize from their own lives.
You don't need to draw, because BunCho (pronounced "boon-cho" — Japanese for "Java sparrow") handles the art and the speech balloons. You only decide two things: what it's about, and where the laugh lands. One line of premise is enough.
- Setup: a situation everyone knows (the night before an exam, you suddenly want to clean your room)
- Build: it goes a little further (the cleaning gets serious)
- Twist: something unexpected (an old notebook turns up at the back of the closet)
- Payoff: the punchline (you read it all night and it's morning)
Tips for writing your premise
You can leave the premise field empty and let the AI choose. Still, a line of your own makes it more likely readers will think "so true."

- Include who and what: "my sparrow fell asleep on my manuscript and I can't write" says who is doing what
- Skip the punchline: the AI suggests punchlines, so the situation is enough
- One idea per strip: two stories won't fit in four panels

Make a four-panel comic on your phone, step by step
Here is the flow after opening /studio/make (Quick Create) in your phone's browser. You can try everything up to entering a premise and picking an art style without logging in.
-
1Open Quick Create and choose the four-panel comic
Open bun-cho.work/studio/make on your phone and tap the four-panel comic option. You can also choose a vertical short video, an anime opening, manga with your favorite character, an explainer video or this week's trending templates.
-
2Write a premise and pick the lead
Write one line in the premise field, or leave it blank to let the AI decide. For the lead, choose automatic or one of the ready-made characters, such as Mochi, BunCho's official Java sparrow.
-
3Swipe through samples to pick a layout and finish
Swipe the sample images left and right to choose the strip format and art style. For the finish, choose between fast and high quality.
-
4Log in and create
Tap the big button to create. At this point you log in with Google or LINE (a messaging app popular in Japan); the login page is in Japanese. Your premise and choices carry over. You see a credit estimate before anything is made and are asked to agree when needed.
-
5Fix, save and share
You can revise the finished strip with words, redraw it, save it to your device, share it or publish it. If one panel bothers you, fix only that panel.
Draw your original character with the same face every time
If you post strips regularly, your lead needs a consistent face. Create a reference sheet in the Studio's manga screen and lock it, and every panel draws the same face, hair and clothes. You can also batch-generate expressions: joy, anger, sadness, fun, surprise, embarrassment and neutral.
Save a locked character to your character library and you can use the same face in other strips, manga and video. Mochi, the official character, is free to use.

Pick a strip format from the templates
Not sure what kind of strip to make? Starting from a template is the shortcut. The Studio's templates cover the strip formats you often see on social media.

Save at the right size for Instagram and X
You can lay out the four panels vertically, as a 2x2 grid or horizontally. For a square Instagram post, 2x2 fits well; for X or a tall phone screen, a vertical strip fits best.
The export tab in the Studio's manga screen offers a single image for social media (such as 1080x1350 portrait for X), one image per panel, PDF and more. To post, download the image and upload it to each platform. You can also turn the strip into a vertical video for shorts.

What you can try for free, and credits
In Quick Create, you can enter a premise and choose an art style without logging in. To actually create, you need the Studio (free for your first 7 days, with 500 credits during the trial). The free trial that turns your own story into a four-panel strip (/studio/try) gives one strip per day once you log in.
Credits per strip depend on the number of panels and image quality, and you see an estimate before creating. On the higher plans, strips made on BunCho's own GPUs cost 0 credits up to a guideline limit.
