Fictoi

Fictoi is a desktop tool for writing visual novels with AI-generated art and AI-assisted scene writing — running entirely on your own machine, using your own API key and your own Stable Diffusion setup. There's no hosted service, no subscription, and no account required. You install it, point it at your own LLM key and your own ComfyUI, and everything — story files, generated art, exported games — stays on your disk.

Two ways in: a 7-step wizard takes a one-sentence premise ("a convenience store clerk notices the same stranger every night") and walks you through plot structure, scene writing, cast, backgrounds/props, art rendering, and bundling — with a "run it all automatically" option if you just want to see what comes out. Or drop into the three-pane dark editor directly: an asset library for characters/backgrounds/props/audio on the left, a node-based story graph in the middle, and AI tools (draft the plot, write dialogue, batch-render art) wired in throughout. Character faces stay consistent across scenes and expressions via IP-Adapter face-locking, and any SDXL-family checkpoint works if you want a different art style than the default.

When you're done, Fictoi bundles your game into a self-contained static web page — no engine, no runtime install for players. Double-click to play locally, or upload the export straight to itch.io as an HTML game. Every export is kept in its own timestamped folder, so packaging never clobbers a previous build. The editor UI, AI-assisted writing, and the exported player itself all support five languages: Chinese, English, French, Spanish, and Japanese.

What You Need

Read this before download.

Fictoi is BYOK: "bring your own key, bring your own ComfyUI." If any of this is a dealbreaker, it's better to find out now than after a refund request.

- Windows 10 or 11.  No macOS or Linux build right now.

- Python 3.10+ installed yourself (from python.org — remember "Add Python

  to PATH"). First run installs a virtual environment and dependencies over

  the internet.

- An LLM API key — DeepSeek, OpenAI, or Claude. DeepSeek is the cheap option to start with. This is a per-token cost billed by the provider, not by us — budget a few dollars of API credit to get started.

- ComfyUI, reachable from somewhere — this is the highest-friction requirement, so don't skip it:

  - Either run ComfyUI yourself on a GPU with "8GB+ VRAM", or

  - Rent a cloud GPU by the hour (AutoDL, RunPod, etc.) and point Fictoi's "ComfyUI address" setting at it — a full walkthrough is included in the app's help docs. Fictoi itself doesn't need a GPU; only wherever ComfyUI runs does.

  - You'll need the `animagine-xl-4.0` SDXL checkpoint (free download) or any other SDXL-family checkpoint you prefer.

  - Character face-locking and expressions need the IP-Adapter custom node and two extra model files — optional, but you'll hit a clear "missing model" message the first time you try an expression without it, with exact file names and folders.

- "No ComfyUI at all?"  You can still write the story, use AI to draft plot and dialogue, and preview the structure — you just can't render images until you connect one.

- "A modern Chromium-based browser" (Edge/Chrome) — the editor is a local web app you open at `http://127.0.0.1:8131`.

 

If you follow the checklist above and something still doesn't work, the in-app "Run Diagnostics" button will point at the specific missing piece —try that before asking for help or a refund.

System Requirements

 - **OS:** Windows 10 or 11 (64-bit). macOS/Linux not currently supported.

- **Processor:** any 64-bit CPU from roughly the last 8 years.

- **Memory:** 8 GB RAM minimum, 16 GB+ recommended.

- **Graphics:** Fictoi itself needs no GPU. If you render locally, whatever

  machine runs ComfyUI needs an NVIDIA GPU with 8GB+ VRAM for SDXL — or skip

  the local GPU entirely and use a rented cloud instance instead.

- **Storage:** roughly 1GB for Fictoi + its Python environment; SDXL

  checkpoints run ~6–7GB each; IP-Adapter models add a few GB more.

- **Network:** required for first-time setup (installing dependencies), for

  every AI call (LLM text + image render), and for cloud GPU use if chosen.

- **Browser:** a modern Chromium-based browser (Edge/Chrome) to use the

  editor, which runs as a local web app.

---

Features

 - **7-step wizard**: one-line premise → full plot → scene dialogue → cast → backgrounds/props → rendered art → packaged game. Editable and re-runnable at every step; "Full Auto" runs start to finish unattended.

- **Three-pane editor**: asset library, node-based story graph, live preview —for when you want to hand-tune instead of wizard-driving.

- **AI-generated character/background/prop art** with face-locking (IP-Adapter) so the same character looks like themselves across scenes and expressions.

- **Bring your own art style**: any SDXL-family checkpoint works (ships configured for `animagine-xl-4.0`; Illustrious and others are drop-in).

- **AI-assisted writing** in five languages (zh/en/fr/es/ja) — plot drafting, scene dialogue, and cast/asset suggestions read your premise and write to match.

- **BGM support** — upload tracks once, use them as music beats in scenes and in AI-written scenes; carried through automatically on export.

- **Cancel and resume** any render/writing job mid-run — already-finished items are kept, re-running skips what's done.

- **Version history** — restore any of your last 30 saves; the current version is auto-archived first.

- **Export = self-contained static web bundle** (HTML/CSS/JS, no server) —playable by double-clicking `index.html`, or upload directly to itch.io as an HTML game.

- **Export history** — every bundle lands in its own timestamped folder; nothing overwrites a previous build.

- **One-click diagnostics** — checks your LLM connection, ComfyUI connection, checkpoint, IP-Adapter, and games folder, and tells you exactly what's missing and where to put it.

- **Five-language UI** (Chinese, English, French, Spanish, Japanese), with per-project story language independent of your UI language.

AI Generation & Content Disclosure

Fictoi the application is regular software (Python + React) — it was not itself generated by AI. **Using it does generate AI content**, though: art via Stable Diffusion (SDXL) through your own ComfyUI instance, and text (scene structure, dialogue, cast suggestions) via your own LLM API key. Any game you export with Fictoi will contain AI-generated art and/or writing unless you hand-edit it out.

Fictoi doesn't generate or moderate content on its own — what comes out depends entirely on the checkpoint, prompts, and LLM you connect. You're responsible for the output you produce and for following itch.io's current content-disclosure and community guidelines, both on this page and on any game page you publish for something made with Fictoi.

FAQ

**Do I need to know how to code?**

No coding to use the editor day-to-day. Initial setup (Python, ComfyUI, model files) is technical — if you're comfortable installing desktop software and following a numbered checklist, you can do this.

 

**Is this a subscription?**

No. One-time purchase. 

 

**Do you host the AI for me, or provide API keys?**

No — Fictoi is BYOK. You bring your own LLM key (DeepSeek/OpenAI/Claude) and your own ComfyUI (local GPU or rented cloud GPU). Those costs are between you and those providers, not us. Nothing runs on our servers because we don't have any — it's all local to your machine.

 

**Can I sell the games I make with Fictoi?**

Yes. Per the license, games you make with Fictoi are entirely yours — sell them, enter them in competitions, publish anywhere, no credit required (though we'd appreciate it).

 

**What languages does it support?**

The editor UI, AI-assisted writing, and the exported game's player all support five languages: Chinese, English, French, Spanish, Japanese. The in-app help docs are currently fully available in Chinese and English only —French/Spanish/Japanese UI users see the English docs until localized versions ship.

 

**I don't have a gaming GPU — can I still use this?**

Yes, rent one by the hour instead. A step-by-step cloud-GPU guide (AutoDL, RunPod) is included in the app. Without any ComfyUI connected, you can still write and AI-draft the story — you just can't render art.

 

**Are updates included?**

Your purchase includes updates within the current version line, per the license. 

 

**What's your refund policy?**

We want you to have the best possible experience! If you encounter technical issues or find the game isn't what you expected, you can request a refund via itch.io Support within 7 days of purchase.

 Please Note: 

- Check Requirements First: Most technical friction stems from the ComfyUI/GPU setup. Please review the "What You Need" section and use the in-app "Run Diagnostics" tool to identify any missing components.

 - Get Support First: If your system meets all requirements but the game still fails to run, please contact us at admin@aicatalysis.com before submitting a refund request. We would love the chance to help you fix it!

Fictoi 是一个本地运行的视觉小说创作工具:用 AI 生成角色立绘、背景、道具, 用 AI 辅助写剧情,全程跑在你自己的电脑上,用你自己的大模型 key、你自己的ComfyUI。没有云端服务,不需要订阅,也不需要注册账号——剧情文件、生成的图、打包的游戏,都留在你的硬盘上。

 两条路都能走通:一句话前提(比如"深夜便利店店员发现每晚都来同一个神秘顾客")丢给「AI 一键成游戏向导」,7 步走完剧情结构、场景对白、角色设定、背景道具、批量出图、打包成游戏——想偷懒就勾「全自动」,一路跑到底看结果;想自己掌控细节,就直接进三栏编辑器:左边素材库(角色/背景/道具/音频),中间是节点式剧情图,AI 铺剧情/写对白/批量出图全程接得上。角色脸靠 IP-Adapter 锁脸,同一个角色在不同场景、不同表情下还是那张脸;想换画风,任何 SDXL 家族的checkpoint 都能直接换。

 做完之后,Fictoi 把游戏打包成一份**独立静态网页**——不需要引擎、玩家也不用装任何东西,双击就能玩,或者直接把导出文件夹丢上 itch.io 当 HTML 游戏上架。每次打包都单独存一份带时间戳的记录,不会覆盖上一次。编辑器界面、AI 辅助写作、连打包出的游戏播放器本身,都支持五种语言:中文、英文、法语、西班牙语、日语。

你需要准备什么

买之前先看这段 —— Fictoi 是 **BYOK**:

自带 key、自带 ComfyUI。如果这对你来说是硬伤,现在知道比退款时才发现好。

- **Windows 10 或 11。** 暂时没有 macOS / Linux 版本。

- **Python 3.10 及以上**,需要自己装(python.org 下载,安装时记得勾选

  "Add Python to PATH")。首次运行会联网建虚拟环境、装依赖。

- **一个大模型 API key**——DeepSeek / OpenAI / Claude 三选一。DeepSeek便宜,适合先试。这是按量计费,厂商收你的钱,不是我们收——准备几美元的API 额度就够起步。

- **能连到的 ComfyUI**——这是门槛最高的一步,别跳过:

  - 要么自己有显卡(建议 **8GB 显存以上**)跑 ComfyUI;

  - 要么租一台云 GPU(AutoDL、RunPod 等),按小时计费,把地址填进 Fictoi设置页就行——工具内附完整的租云 GPU 教程。Fictoi 本体不需要显卡,需要显卡的是跑 ComfyUI 的那台机器(不管是本机还是云上)。

  - 绘图模型用 `animagine-xl-4.0`(免费下载)或任何你喜欢的 SDXL 家族checkpoint。

  - 角色锁脸和表情需要装 IP-Adapter 自定义节点和两个额外模型文件——不装也能用,只是第一次出表情时会提示「模型缺失」,并且会告诉你具体缺哪个文件、放哪个目录。

- **完全没有 ComfyUI 也能用**:能写剧情、能用 AI 铺结构写对白、能预览结构,只是不能出图,等你连上 ComfyUI 随时能补。

- **一个现代的 Chromium 内核浏览器**(Edge/Chrome)——编辑器是个本地网页,地址是 `http://127.0.0.1:8131`。

按上面清单走一遍,还是哪里不对,先点应用内「一键体检」,它会直接告诉你缺哪一项——比先来问人或先申请退款更快。

---

## 系统需求

- **操作系统:** Windows 10 或 11(64 位)。暂不支持 macOS / Linux。

- **处理器:** 近 8 年内的 64 位 CPU 均可。

- **内存:** 最低 8GB,建议 16GB 以上。

- **显卡:** Fictoi 本体不需要显卡。如果在本机出图,跑 ComfyUI 的那台机器需要 NVIDIA 显卡、8GB 显存以上跑 SDXL——或者干脆用云 GPU,本机完全不需要显卡。

- **存储空间:** Fictoi + Python 虚拟环境约 1GB;SDXL checkpoint 每个约6–7GB;IP-Adapter 相关模型再加几 GB。

- **网络:** 首次安装依赖需要联网,每次 AI 调用(大模型文字 + 出图)需要联网,用云 GPU 也需要联网。

- **浏览器:** 现代 Chromium 内核浏览器(Edge/Chrome),编辑器是跑在本地的网页应用。

---

功能清单

- **7 步向导**:一句前提 → 完整剧情结构 → 场景对白 → 角色 → 背景/道具 →出图 → 打包成游戏。每步都能改、能重来;勾「全自动」一路跑到底。

- **三栏编辑器**:素材库 + 节点式剧情图 + 实时预览——想自己精修就别用向导。

- **AI 出角色/背景/道具图**,配 IP-Adapter 锁脸:同一角色在不同场景、不同表情下还是原来那张脸。

- **画风任选**:任何 SDXL 家族 checkpoint 都能用(默认配置 animagine-xl-4.0, Illustrious 等系列直接换)。

- **AI 辅助写作**,五语言(中/英/法/西/日):AI 铺剧情结构、写场景对白、推荐角色/素材阵容,读你的前提自动匹配。

- **BGM 支持**:传一次曲子,剧情里的「音乐」beat 和 AI 写场景都能用,打包自动带走。

- **随时取消、断点续跑**:出图/AI 写作跑到一半可以取消,已完成的保留,重跑自动跳过做过的。

- **历史版本**:最近 30 次保存随时能恢复,恢复前还会自动存一份当前版。

- **导出 = 独立静态网页**(HTML/CSS/JS,不需要服务器):双击 `index.html`直接玩,或原样上传到 itch.io 当 HTML 游戏。

- **导出记录**:每次打包单独存一个带时间戳的文件夹,不覆盖之前的版本。

- **一键体检**:逐项检查大模型连接、ComfyUI 连接、绘图模型、IP-Adapter、游戏目录,缺什么直接告诉你去哪装。

- **五语言界面**(中/英/法/西/日),每个项目的剧情语言可以和界面语言不同。

 AI 生成内容声明

Fictoi 这个应用本身是用常规代码写的(Python + React),**不是** AI 生成软件。但用它确实会生成 AI 内容:图是通过你自己的 ComfyUI, 用 Stable Diffusion(SDXL)出的, 文字(剧情结构、对白、角色建议)是通过你自己的大模型key 生成的。用 Fictoi 打包出的游戏,只要你没有手动全部改写,就会包含 AI生成的美术和/或文案。

Fictoi 本身不生成也不审核内容——出来的东西完全取决于你连的 checkpoint、提示词和大模型。生成的内容由你自己负责,发布这个页面、以及发布用 Fictoi做出的任何游戏时,请遵守 itch.io 当时的 AI 内容披露规则和社区准则。

常见问题

**要会写代码吗?**

日常用编辑器不需要写代码。初次配置(Python、ComfyUI、模型文件)是技术活——如果你能照着清单一步步装软件,就能搞定。

 

**这是订阅制吗?**

不是,买断制,一次购买。

 

**AI 是你们提供的服务吗?**

不是。Fictoi 是 BYOK:你自带大模型 key(DeepSeek/OpenAI/Claude)、自带ComfyUI(本机显卡或租的云 GPU)。这些费用是你和对应厂商之间的事,跟我们没关系——我们没有服务器,所有东西都跑在你自己的电脑上。

 

**用 Fictoi 做的游戏能卖钱吗?**

能。按授权说明,用 Fictoi 做出的游戏完全归你——发布、售卖、参赛都行,不需要注明用了 Fictoi(注明了我们会很开心)。

 

**支持哪些语言?**

编辑器界面、AI 辅助写作、导出游戏的玩家界面都支持五种语言:中/英/法/西/日。应用内的帮助文档目前只有中文和英文两个完整版本——法语/西语/日语界面用户在帮助页看到的是英文文档,等后续补上。

 

**没有好显卡能用吗?**

能,租一台云 GPU 按小时用就行,工具里附了完整的 AutoDL/RunPod 教程。完全没连 ComfyUI 也能先写剧情、用 AI 铺结构,就是暂时不能出图。

 

**更新要另外收费吗?**

按授权说明,买断已含同一版本线内的所有更新。

 

**退款政策是什么?**

我们希望您能拥有完美的体验！如果您遇到技术问题，或者发现游戏不符合您的预期，可以在购买后 7 天内通过 itch.io 官方支持提交退款申请。

请注意：

请先检查配置要求：绝大部分技术问题都源于 ComfyUI 或显卡（GPU）的配置。请先阅读“准备工作（What You Need）”部分，并使用应用内的“运行诊断（Run Diagnostics）”工具来排查缺失的组件。

请先联系技术支持：如果您的系统完全满足配置要求，但游戏仍无法运行，请在提交退款申请之前通过 admin@aicatalysis.com 联系我们。我们非常希望能有机会帮您解决问题！
