Free AI 4-Koma Comic Script Generator

4-koma strips live and die by their fourth panel — the twist, the punchline, the gut-punch that pays off the first three. This 4-koma script generator builds exactly that structure: setup, development, escalation, and payoff, all in four tight panels. Describe a premise (a character dynamic or single funny idea works best), pick a genre and length, and get a script formatted for the classic yonkoma layout. It's ideal for gag comics, character-driven humor strips, or short serialized bits you can post regularly. Free to try with no login — and if you want the punchline illustrated, Comistitch can turn the script into finished 4-panel art.

Your 4-Koma Script

PANEL 1 (Setup): A KNIGHT bursts into a cave, sword raised. "DRAGON! Face me!" PANEL 2 (Development): The DRAGON, enormous and scaled, visibly trembles behind a small rock that does not hide it at all. PANEL 3 (Escalation): KNIGHT: "...Are you hiding?" DRAGON (small voice): "No." PANEL 4 (Punchline): The dragon is now wearing the rock as a hat. KNIGHT sighs and sits down to negotiate instead.

Input

Your 4-Koma Script

PANEL 1 (Setup): A tiny CAT puffs up dramatically at the front door. "Who goes there!" PANEL 2 (Development): A DELIVERY WORKER knocks. The cat hisses fiercely, tail huge. PANEL 3 (Escalation): The door opens. The cat charges forward heroically — and skids straight past the worker's shoes. PANEL 4 (Punchline): The worker pets the "guard dog" while it purrs, mission apparently accomplished.

Frequently Asked Questions

What is a 4-koma script exactly? +
4-koma (yonkoma) is a Japanese 4-panel comic strip format built around a setup-development-twist-punchline structure, similar to a comedic short story compressed into four beats. This generator writes scripts specifically in that structure.
Does this only work for comedy? +
Comedy is the most common 4-koma use, but the structure also works for slice-of-life or bittersweet strips — the fourth panel becomes an emotional beat instead of a joke. Describe your intended tone in the premise field.
Can I generate a whole week of daily strips at once? +
Each generation produces one 4-panel strip script. For a recurring strip, generate one script per premise/gag and reuse the same characters across multiple runs.
How is this different from the manga script generator? +
The manga generator paces a full scene or chapter across many panels; the 4-koma generator compresses one complete comedic or emotional beat into exactly four panels with a punchline structure.
Do I need specific character names before generating? +
No — describe the dynamic (e.g. "an overly serious knight and his chaotic pet slime") and the script will use placeholder names you can swap, or pair it with the character name generator first.
Can I turn this into an illustrated strip? +
Yes — copy the script into Comistitch to generate a 4-panel illustrated strip in your chosen art style, with consistent characters across all four panels.
