Anvilmod · AI modding engine

Pick a game.
Describe an idea.
Get a working mod.

Anvilmod turns plain-English ideas into complete mod projects for supported games — source code, configuration, dependencies, build steps, and install instructions. Return any time to revise, extend, or refactor a saved project.

How it works

Three steps from idea to installed mod.

The first cut is just the start. Every project is saved, so you can come back and shape it further — that's where Anvilmod earns the "tool" label instead of the "one-shot generator" label.

  1. 01Step 1 of 3

    Pick a supported game

    Choose from the games Anvilmod knows how to mod. Each one has a legitimate, documented framework — no pirated files, no reverse engineering.

  2. 02Step 2 of 3

    Describe the idea plain-English

    "Helicopter backup at four-star wanted levels." "A dialogue UI that pauses traffic." "A regional economy that remembers what you bought." That outline is enough to start.

  3. 03Step 3 of 3

    Receive the full mod project

    A working project lands in your account — source files, configuration, dependencies, build steps, install instructions. Revise, extend, refactor, or start another.

What you get

Five tools aimed at the same thing — shipping mods that actually install.

Each tool is scoped tightly. The Generator produces the project; the others help you maintain it across new patches, new ideas, and things you don't yet know how to read.

The Generator
A first-class mod project tailored to your game: layout, code, configuration, install steps, dependency graph. The starting point you can actually build on.
Mod Search
A scoped search engine over each game's framework docs and API surface. Ask in English; get the method, the parameter, and the worked example.
Mod Debugger
Paste a stack trace, a console log, or upload a file. Mod Debugger walks you through what broke and what to change — in plain language, not engine jargon.
Mod Upgrader
When your game patches its scripts or a framework ships a new version, Upgrader diffs your project against what changed and proposes the migration.
Mod Explainer
Drop in code from a forum post, a tutorial, or a download. Explainer walks through what it does, line by line, in terms a non-coder can actually follow.

Inspiration

Four starter ideas worth riffing on.

Each one links into the generator below with the game pre-selected and the idea prefilled. Tweak, extend, or save and come back with a different angle.

Scope & boundaries

Anvilmod stays on the legitimate side of modding.

Generative AI has earned a reputation for shoveling out junk. The boundary isn't paperwork — it's what the engine refuses to do.

Always

  • Only legitimate, documented modding frameworks
  • Every project lists its supported game version, framework version, and dependencies
  • Plain-English revisions — describe what to change; the engine rewrites the bits that need it
  • Saved projects you can return to and extend, free account, no subscription lock-in

Never

  • Pirated, stolen, or cracked game files
  • DRM bypasses, license workarounds, or cracked executables
  • Anti-cheat circumvention or anything that skirts a game's fairness systems
  • Mods that ship copyrighted assets from the base game, DLC, or other studios
