# Synagy Games

> Synagy Games is an AI game builder for people who can't code. You describe a game or a Minecraft mod in plain words, a crew of AI agents plans it with a price, builds it while you watch, play-tests it and fixes it. It works inside Minecraft: Java Edition, inside the Unity Editor (free package, Unity 6) and inside Roblox Studio (free plugin, beta). One free Synagy app (Windows, macOS, Linux) sets up all three with one click; no AI agent or coding tool is needed. Open to everyone with a free account: no waitlist, no closed beta, no invite. Made by two people in Germany, built in public.

## Key facts

- Synagy app: one free desktop app for Minecraft, Unity and Roblox Studio. It finds the game or editor, installs it from the vendor if it is missing, adds Synagy and keeps everything up to date.
- Synagy for Minecraft: make mods directly inside Minecraft by typing. Describe a mod or a structure in one line, watch it being built live in the Synagy Workshop world, every part is game-tested, and you keep the result as a real .jar with full source code. Publicly available since 2026-10-10 (no beta, no waitlist). Built and played on Minecraft: Java Edition 26.2 with Fabric; the Synagy app sets up Fabric and the Synagy mod and starts the game. Finished mods stay private until you press "Publish on Synagy" in the Synagy window: the mod uploads and you add a title and pictures on Explore (synagy.org). Mods made only from Synagy building blocks go live after an automatic check; mods with their own Java code are reviewed by the Synagy team first. Other players download the .jar or install it with one click in the Mods tab of the Synagy app.
- Minecraft versions: mods are built and played on 26.2 with Fabric. The free Mod Compiler in the Synagy Studio (Minecraft tab) also builds your finished Synagy mods for NeoForge 26.2, Fabric 26.3 and Fabric 1.21.1; every build passes the same game tests on a real server of that version first. In development: NeoForge for 26.3 and 1.21.1, then 1.20.1 and Forge, and porting other people's open-source mods to older versions. Bedrock Edition is not planned yet.
- Synagy for Unity: one free package for the Unity Editor (Unity 6 / 6000.0 or newer, Windows, macOS, Linux; tested on 6000.0, 6000.3 and 6000.6). Two ways in: the Synagy chat (our agent crew plans every part with a price in credits, writes C# scripts, scene objects and materials into Assets/Synagy/, compiles, runs Play mode, checks a screenshot and fixes itself), or, optionally, your own agent (Claude Code, Codex, Cursor, Antigravity, Hermes and any other MCP client) driving the editor through the free Synagy MCP server. The chat needs no agent.
- Synagy for Roblox Studio (beta): a free Studio plugin with the Synagy window built in. Sign in once with your synagy.org account, describe an experience, check the plan with its price in credits, and Synagy writes Luau scripts, builds parts in the open place, syntax-checks and playtests with an avatar. Optionally, your own agent can also drive Studio through the Synagy MCP server; its roblox_generate tool makes 3D props from text with Roblox's own Cube 3D model (Roblox beta, saved to your Roblox account). By default it builds in the classic stud look of the top collect, steal and grow games (studded toy plastic, chunky block animals with big heads, bright soft-shadow lighting, rarity labels) with Synagy's free SynagyStudKit, which it places in ReplicatedStorage; the look is "Classic Studs" under Skills › Style, and an idea that asks for another style (realistic, horror, low poly …) turns it off. Your own agent gets the same look through the MCP server (engine_guide topic stud-style, roblox_files op kit). Tested in Roblox Studio 0.741; the Synagy window itself makes no images or meshes yet.
- Browser games on synagy.org: describe a game and Synagy builds a playable HTML5 game in the browser. New games come with sliders (speed, lives, difficulty, colors) in the Tune panel: changes show live and saving them as a new version costs no credits; older games get sliders with one edit. The builder picks fitting models, textures, skies and sounds from a free CC0 library of about 4,700 assets (Poly Haven, Kenney, KayKit, Quaternius, ambientCG) with a search that understands English and German, also when you change a game later. "Clone" rebuilds the mechanics of a game you show it (screenshots, a clip, or a Steam, TikTok, YouTube or itch.io link) as an original game with its own name and art: it first takes the game apart into core loop, controls, camera, progression, game feel and art direction, suggests twists that make your version clearly original (you keep or drop each one), and blocks the original's names plus well-known game brands from the title and code. If a new game does not start, Synagy fixes it once automatically. The Look tile offers eight art styles (Pixel Art, Toon Cel, Diorama, Clay Toy, Voxel, Neon Night, Realistic, Dark & Moody); each goes to the builder as a concrete recipe (lighting, materials, palette, effects), and its preview is a real render of that recipe with free library assets (Poly Haven scans, Kenney and KayKit models). "Make an ad" (Creator plan, same daily limit as clips) renders a 9:16 or 16:9 game ad in the browser: games with a built-in bot play themselves while they are recorded (otherwise you play), the cuts land on real game moments (score jumps, level ups, lost lives, game over, win) and on the beat, with a hook line from the first frame, captions, a beat bed under the game sound and a branded end card with the game's best frame, its name, "Play free in your browser" and the play link. The ad is rendered frame by frame at a steady 30 fps (WebM).
- Assets page on synagy.org: generate sprites, textures, images, sound effects, music and 3D models (GLB) for any game, or pick from the free CC0 library. Recipes per kind (character, creature, prop, weapon, vehicle, pickup, UI icon, sprite sheet, ground, wall, tile set, background, sky, title art, UI click, explosion, menu or boss music, 3D prop or building …) add the right framing for you, "Sharpen" tidies a description for free, and a chosen style or style image stays for the next assets so a set looks consistent. The styles are the same eight looks as the Build page's Look tile, so a game and its generated assets match. Sprites can be checked on transparent, light, dark or grass ground; 3D models spin on a turntable; your own sounds play straight from the card.
- Assist and voice input on synagy.org: Assist, the game-design and prompt helper, opens from a button in the bottom right corner of every Studio page as a side panel next to the page, so nothing is covered on wide screens. It sees the page you are on; on the Build page it also sees your game, its errors and tests, and it can hand you a ready prompt that goes straight into the build field. A microphone button lets you speak instead of typing on the Build page, in Assist and for asset prompts (speech to text only, Synagy does not talk back). On the Build page your spoken idea is improved into a stronger prompt automatically, and you can keep your own words instead. A dictation costs about 2 credits (up to 4 for a full minute).
- Who it is for: creative gamers with game ideas who don't program and don't know an engine, and developers who want an agent that can actually build and test inside Unity.
- What makes it different: you watch the game being built live and can interrupt or redirect the agents at any time; a bot plays every build before you see it; credits are charged per working part instead of per prompt; the project stays yours (a normal Unity project or a Minecraft .jar with source).
- AI transparency (EU AI Act Art. 50): every chat says that you are working with AI agents, and the images, sounds, 3D models, games and Minecraft mods Synagy generates carry a machine-readable AI-generated mark in their file metadata (IPTC digital source type "trainedAlgorithmicMedia"). Blog posts written by our AI writer say so.
- Not yet available: Unreal, Minecraft Bedrock Edition and Forge. NeoForge comes only through the Mod Compiler, not inside the game.

## Pricing and free use

- Free to start: a free account gets 25 Free Credits every day (reset 00:00 UTC, not stackable) for builds that run on free AI models, once its email address is confirmed. No card, no payment needed to try Synagy. Throwaway email addresses cannot open an account. On a finished template, a free-model build changes the template's theme, names, texts, colours and tuning values and keeps its tested game code; new mechanics need a stronger model.
- Free beta, payments are paused: Synagy is free to use right now. Plans, the free trial, extra build slots and credit top-ups cannot be bought at the moment, and nothing is charged. Every account keeps its 25 Free Credits every day. Anyone who already has a plan can still cancel it in their account. The Minecraft mod and the Unity and Roblox Studio windows no longer offer top-ups or upgrades. Signed-in users can join (or leave) the waitlist for paid plans on https://synagy.org/waitlist (also on /pricing#waitlist) and get one email when plans and top-ups open (the newsletter is a separate, optional choice).
- Planned monthly plans after the free beta (not bookable yet; cancellable any time, prices in euros including VAT): Go €2.99 (3,500 credits), Starter €8.99 (11,000 credits), Creator €24.99 (32,000 credits), Studio from €79.99 (115,000 to 500,000 credits). The cheapest paid plan is Go.
- Planned pay as you go after the free beta (not bookable yet): top up from €5 (up to €500). €1 buys about 1,111 credits, so 1,000 credits are about €0.90. Topped-up credits never expire; plan credits expire on the next billing day (Studio rolls them over).
- Browser studio models (synagy.org Build and Assets pages): four tiers, unlocked by plan. Without a plan only the Free model runs (on the 25 daily Free Credits); Go unlocks Turbo plus the image and music models, Starter unlocks Pro, Creator unlocks Max. Pro and Max are billed at real model cost × 2 instead of × 3, and small changes (a colour, a speed, a text) on Pro or Max run on Turbo automatically, with a one-click option to keep the bigger model.
- One credit balance works in Minecraft, Unity and Roblox Studio. The Synagy app, the Unity package, the Roblox Studio plugin and the MCP server are free.
- Every build shows its price in credits before anything starts, and a part that fails costs nothing. Confirming a plan holds its maximum price on your account (shown balance stays the same, held credits can't be used by a second build at the same time); each part is charged only at its real cost once it is done. A part you stop, or leave by closing the editor, is charged for what it used so far. Stronger AI model tiers cost more per build (shown as a factor, from 1× upwards); the plan decides which tiers you can pick.

## How builds are tested

- Every Minecraft part passes hard gates before it is charged: schema and balance checks, a Gradle compile against the target version, generated GameTests (block can be placed and mined with the right drop, recipe crafts, mob spawns and moves, mechanic triggers), a 60-second crash test on a headless dedicated server, texture and structure lint, then an AI judge on preview images. Parts that fail all attempts are free.
