AI game development assistant
Describe your game, scene, or animation and get work you can build on: core mechanics and a build plan, a playable HTML canvas game with a real game loop, a Three.js scene wired up with a camera and lighting, a Remotion video composition ready to render. Zeplik builds from your project, your engine, and your constraints, not a generic tutorial, and it works across every frontier model in one chat. It is honest about the line too: it drafts design and code and tells you what to run and profile before you ship.
Who it is for
- Solo and indie developers building games without a full engine team
- Web developers adding 3D, WebGL, or interactive graphics to a site
- Creative coders making generative art and motion pieces in code
- Anyone scripting programmatic video with Remotion or Motion Canvas
How it works
Describe your project and engine
Tell Zeplik what you are building, the engine or framework, for example Unity, Godot, Three.js, or a plain HTML canvas, and your target platform and constraints, or paste the code you already have. The work is grounded in your setup, so the guidance fits your project instead of a generic sample.
Ask for the work you need
Say it plainly, for example "design the mechanics for this game" or "build the game loop and input handling." Zeplik routes to the right skill without you naming it, and you can steer the engine, the style, the scope, and the depth.
Run it, profile it, iterate
You get a design, draft code, or a scene setup with the reasoning shown, and you can iterate in the same conversation. Run it in your own project, profile it on real hardware, and confirm it behaves and performs correctly before you ship.
What you can ask
Real asks in plain language, and the concrete deliverable you get back. Open the assistant to try your own; nothing runs until you send it.
Design the core mechanics and a build plan for the game idea I'll describe.
A design brief for your concept: the core loop, the mechanics and how they interact, a progression and difficulty outline, and a phased build plan that gets you to a playable prototype first, grounded in the idea you gave it.
Help me build a playable HTML canvas game. Start with the game loop and input.
A working foundation: a fixed-timestep game loop, input handling, and the render and update split, in draft code you run in your own project, with the next steps to add entities, collision, and state.
Set up a Three.js scene for the 3D web experience I'll describe.
A scene scaffold: the renderer, camera, and lighting setup, a loop, and the object and material structure for what you described, with the performance considerations for the web called out.
Make generative art from this idea, in code I can tweak.
A p5.js or canvas sketch built around your concept: the generative system, the parameters to play with, and the reasoning behind the composition, in code you can run and iterate on.
Build a Remotion video from this script: the composition and the render setup.
A Remotion project: the React composition code for the scenes, the timing and animation, and the render configuration, structured so you can preview, adjust, and export it.
Review my Remotion project and fix what breaks the render.
A review of the code you paste: the render-unsafe patterns, the timing and frame issues, and corrected, render-safe React video code with the reasoning for each change.

The assistant routes to the right skill for you. Each one below is a focused, ready-to-run workflow; follow a link to see exactly what it does.
Game design and build

- Motion CanvasProgrammatic videos in TypeScript with scene code and project config.
What a general chatbot gets wrong on game and graphics code, and what is different here
Game and graphics code is where a general model sounds fluent and hands you something that will not compile, will not render, or tanks the frame rate. The APIs move fast, the performance rules are unforgiving, and a plausible-looking loop can quietly drop frames. Zeplik grounds the work in your engine and project and is honest about what it cannot run for you.
The failure. A general model writes engine or Three.js code against an API from its training cutoff, so the sample does not compile or uses a method that was renamed.
How Zeplik grounds it. Zeplik builds around the engine and version you tell it and flags where a call depends on a fast-moving library, so you verify it against current docs rather than pasting code that no longer runs.
The failure. Asked for a game loop or a render setup, a general model hands you a naive version that ignores timestep, frame budget, and cleanup, so it stutters or leaks the moment it runs.
How Zeplik grounds it. The game and web-graphics skills design for the real constraints: fixed-timestep loops, the update and render split, resource cleanup, and the web performance rules, so what you build holds its frame rate instead of demoing once and stuttering.
The failure. A general model claims code will run at a given frame rate or on a given device, as if it had profiled it.
How Zeplik grounds it. Zeplik is upfront that it does not run or profile your project. It writes the code and explains the performance trade-offs; you run it in your engine and profile it on real hardware before you trust the numbers.
What it does not do
Knowing the boundary is part of using it responsibly. This is where a person, not the assistant, has to own the call.
- It drafts, you run it. Every design and code sample is a starting point to build and test in your own project. It does not run, render, or play your game for you.
- Verify fast-moving APIs. Engine versions, Three.js, and Remotion change often. Confirm every method and config against current documentation before you depend on it.
- Profile performance yourself. Frame rate and memory depend on your assets, target device, and scene. Profile on real hardware; do not trust a predicted number.
- Assets and rights are on you. It writes code and design, not licensed art, audio, or fonts. Source and clear the rights for anything you ship.
This is game and interactive-development guidance and draft code for your review, not tested, shippable software. It reflects general engine and web-graphics practice, not your exact engine version, target platform, or performance budget, so run it in your own project, profile it on real hardware, and confirm it behaves and performs correctly before you ship.
Frequently asked questions
- Is the AI game development assistant free?
- Zeplik is free to start and every new account includes credits. These skills run like any other Zeplik chat, so you spend only normal usage credits on the model you pick, with the cost shown before you send.
- Which engines and frameworks does it cover?
- Game engines like Unity, Godot, and Unreal for design and code guidance, plus web stacks: HTML and JS canvas games, Three.js and React Three Fiber for 3D, p5.js for generative art, and Remotion and Motion Canvas for programmatic video.
- Can it actually run or preview my game?
- No. It writes the design and draft code and explains the trade-offs, but it does not run, render, or profile your project. You build and test it in your own engine or browser. It is honest about that rather than claiming a frame rate it never measured.
- Will the code compile and work?
- Treat it as a reviewed draft. It builds around your engine and version and flags fast-moving APIs to verify, but engine and library versions change, so run it in your project, confirm the calls against current docs, and test before you ship.
- What do I need to give it?
- A description of what you are building and your engine or framework is enough to start. For sharper work, paste your existing code, your target platform, and any performance budget. The guidance is grounded in what you share.
- Can it help with programmatic video, not just games?
- Yes. It builds Remotion and Motion Canvas projects from a script: the composition code, the timing and animation, and the render setup, and it can review an existing Remotion project for render-safe code.
