2D Character Sprite Generator
An AI sprite maker for characters: generate heroes, enemies and NPCs in any art style, visually consistent as a cast, posable, and exported as clean transparent sprites.
What is an AI 2D character sprite generator?
An AI 2D character sprite generator creates original game characters, like heroes, enemies and NPCs, from a text prompt, then animates them with walk, run, idle and attack cycles. Ludo generates consistent 2D character sprites in 32 art styles and exports packed, engine-ready sprite sheets for Unity, Godot and GameMaker.

Ivy, Rowan and Professor Hale from one recipe in the Watercolor style, every expression with Edit with Mask and a new outfit with Edit Image, then a greenhouse background, a dialogue box and a name plate put together in a Ren'Py scene.
How to Make Visual Novel Sprites with AI (Consistent Cast, Every Expression, Ren'Py Scene)
Transcript: How to Make Visual Novel Sprites with AI (Consistent Cast, Every Expression, Ren'Py Scene)
Rowan: Late again, Ivy.
Ivy: I was out picking lavender. For you, actually!
Rowan: For... for me?
Every image in this visual novel scene, the cast, every face, the background and even the dialogue box, came out of ludo.ai.
Here's how to make your own, start to finish.
Open the Image Generator, keep Generation Mode on Generate New, and pick the Sprite type, so she comes back cut out on a transparent background.
In Filters, set Art Style to Watercolor, a soft painted look that suits a visual novel, and Aspect Ratio to Portrait 9:16, so there's room for the whole figure.
The prompt is a recipe: her name and who she is, hair and eyes, the outfit, one prop, and standing and facing the viewer, full body.
Generate, and pick the take you'd happily look at for a whole game.
Ours came out like this.
Ivy: Obviously, this one.
For the rest of the cast, keep every setting and the same recipe, and only change the person.
Giving them the same academy cloak helps them read as one cast.
Rowan: It looks better on me.
Now the expressions.
Open Generation Mode, the menu that also holds Edit Image and Upscale Image, and pick Edit with Mask.
Choose her sprite, press Draw Mask and paint over her face, then describe the new one: angry, frowning, cheeks puffed in a pout.
The mask limits the edit to the painted area, so her hair, outfit and pose stay where they were, and the sprite doesn't jump when her mood changes.
One description per mood: happy, angry, sad, surprised, flustered and smug, then a few more for Rowan and Professor Hale.
Hale: I do not do flustered.
For clothes, switch to Edit Image and write it out: change only her outfit to a summer festival yukata, and keep her face, hair and pose.
We did the same for a pose, hands on hips for her confident moments.
Backgrounds come from the Static Background type, in the same Watercolor style at Landscape 16:9: an empty greenhouse, painted edge to edge, so the cast can stand in it.
Even the dialogue box and the name plate are Ludo images, from the UI Element type at a wide aspect ratio, already on transparent backgrounds.
For a crisp full-screen scene, Upscale Image raises the resolution.
Download each one, it saves as a PNG, and put the sprites in your Ren'Py project's images folder, named by character and mood, like ivy angry.
A script line that says show ivy angry swaps her face on that line, and the box and the plate go in the gui folder, with a few style lines from the pinned comment.
Here's the scene in Ren'Py.
Hale: Both of you. Inside. Now.
Ivy: Professor Hale?!

Rowan: I'm not!

Generate one character, then use it as the style anchor for the rest: the adventurer, shopkeeper and guard here all come from one anchor. The whole roster, drawn by the same artist.
Style exploration
The same knight princess in 16-bit, chibi and hand-painted. See your protagonist in every style before locking the art direction.
