Character studio · outfits & emotion setsThere are plenty of ways to create visual novels with AI. LacunaEngine is built on the models that top the public benchmarks for storytelling, image generation, and speech — so what you imagine arrives at the quality your readers expect.
The story assistant, suggestions, and prompt generation run on Anthropic's Claude — pick Sonnet 5 for everyday speed, Opus 4.8 for depth, or Fable 5, the model ranked #1 for creative writing. Claude models hold the top four spots on EQ-Bench's longform writing leaderboard, and the same intelligence that leads SWE-bench Pro keeps your branching script logically airtight.
Every sprite, outfit, emotion, background, and map is generated with Google's Nano Banana 2 — the model that topped LMArena's image leaderboard by the largest margin ever recorded. It keeps up to five characters on-model across generations, which is exactly what a visual novel demands of its cast.
Character voices come from Inworld, whose speech models are designed for game characters first — heroes, villains, narrators — and top Artificial Analysis's blind voice-quality rankings. Emotionally directed line reads mean your cast sounds like a cast before you ship a single scene.
From overnight game jams to full episodic releases — across every genre.

An AI visual novel maker is a studio that turns a written idea into a playable game. LacunaEngine runs entirely in your browser: you imagine the story, and it generates the characters, art, music, and branching script — then lets you play, publish, and export the result as a real visual novel.
Traditional engines like Ren’Py give you a scripting language and leave the writing, art, and music to you. LacunaEngine covers that production side with AI while keeping the same kind of script underneath — and since you can export a Ren’Py-compatible project at any time, you are never locked in.
No. You describe the story and LacunaEngine handles the art, the script, and the game logic. Everything stays editable — if you want to write scenes by hand or tweak the script directly, you can.
Credits power every AI generation — story scenes, character sprites, outfits, emotions, backgrounds, panoramas, and maps. Each action shows its credit cost before you confirm, so there are no surprises.
New accounts get full access to every feature for 14 days plus 300 free credits — no card required. After that you stay on the free tier unless you upgrade.
Any genre a visual novel can carry: romance, mystery, sci-fi, fantasy, horror, slice of life, thrillers. Stories can be linear or heavily branched, with multiple routes and endings driven by the choices your readers make.
