AI tools for Roblox

Best for Props and characters from text or an image, rigged if needed

Can you ship it?

Yes, with conditions Free tier is CC BY 4.0: credit Meshy. Paid plans make assets privately yours. Source

Price

Free 100 credits/mo (CC BY 4.0). Pro $20/mo

Works with

Unreal, Unity, Godot, Blender, Roblox

Text or image to 3D with texturing, auto-rigging and an animation library. Its free tier is unusually usable for a shipping game: assets are CC BY 4.0, so commercial use is allowed if you credit Meshy. Paid plans make assets fully yours.

Best for High volume of game-ready meshes with part segmentation

Can you ship it?

Paid plan needed Pro ($20/mo) or higher. Free models are public and non-commercial. Source

Price

Free 200 credits (non-commercial). Pro $20/mo

Works with

Unreal, Unity, Godot, Blender, Roblox, Maya

Fast generation with smart segmentation and retopology, plus an Unreal bridge. Watch the license: free-tier models are public and non-commercial, so anything you plan to ship needs a paid plan.

Best for Game-ready props from parametric templates and AI

Can you ship it?

Paid plan needed Plus ($12.50/mo yearly) allows commercial use; free Guest plan is personal only Source

Price

Free (1 generation/day, personal use). Plus $15/mo or $12.50/mo billed yearly

Works with

Exports GLB, OBJ, FBX; Unity, Unreal, Godot, Blender, Roblox plugins

Sloyd mixes text and image to 3D with editable parametric templates, polycount control, auto-rigging and plugins for Unity, Unreal, Godot, Blender and Roblox. One catch: the free Guest plan is personal use only with one generation a day and no plugins, and reselling assets on marketplaces needs Pro.

Best for Deep C++ work across a large codebase

Can you ship it?

Paid plan needed Needs a paid Claude plan (Pro from $17/mo yearly); terms assign outputs to you. Source

Price

Included with Claude Pro ($20/mo in the US; varies by region)

Works with

Any (official Unreal plugin available)

A general coding agent that runs in your terminal or IDE. On its own it knows C++, not your editor state; paired with Epic's official skills plugin above, it can also drive the running editor.

Best for Unreal C++ inside an AI code editor

Can you ship it?

Yes, free tier Terms assign your code suggestions to you, with no plan limits Source

Price

Free; paid from $8/mo (Plus), Premium $30/mo, Super $100/mo, Ultra $200/mo

Works with

Any

An AI-first code editor that many Unreal developers use for C++. It works with community and official Unreal MCP servers, so it can reach the editor too, but out of the box it only sees the code you open.

Best for AI coding in VS Code, Visual Studio, Rider

Can you ship it?

Yes, free tier GitHub claims no ownership of output; you check any third-party licenses Source

Price

Free (2,000 completions, 50 chats/mo). Pro $10/mo. Pro+ $39/mo

Works with

VS Code, Visual Studio, JetBrains, Xcode, Neovim, CLI

Copilot gives you completions, chat and an agent mode inside VS Code, Visual Studio and JetBrains IDEs, which covers C++, C#, GDScript and web game code. The free tier is capped at 2,000 completions and 50 chat requests a month, and on personal plans GitHub may use your inputs and outputs to train models unless you opt out.

Best for Physics-correct keyframe animation with AI autoposing

Can you ship it?

Paid plan needed Indie ($8/mo yearly) if revenue is under $100k a year; Pro above that. Source

Price

Free (non-commercial). Indie $8/mo yearly or $19 monthly, under $100k revenue

Works with

Exports FBX, GLTF, USD

AI posing and physics tools for hand-keyed animation. The free version is non-commercial and exports only its own format, so you need Indie to get FBX into Unreal. Yearly plans convert to a perpetual license.

Best for Single-camera iPhone or video mocap

Can you ship it?

Paid plan needed Standard plan ($35/mo yearly) or higher; Personal plan is non-commercial Source

Price

Free (view only). Personal $15/mo (non-commercial). Standard $50/mo or $35/mo billed yearly

Works with

Exports FBX, BVH, USD, BLEND

Move One turns a single phone or video clip into body animation you can export as FBX, BVH, USD or a Blender file. The catch: the free plan is view only and the $15 Personal plan is non-commercial, so shipping a game with it starts at the Standard plan.

Best for Text and video to character motion

Can you ship it?

Yes, with conditions Free-plan output is CC BY 4.0, so credit Uthana; paid credits make it yours Source

Price

Pay-as-you-go credits, no subscription. Text-to-motion from $0.02/sec, video-to-motion $0.05/sec

Works with

Exports FBX, GLB, BVH; Blender and Maya plugins

Uthana generates humanoid animation from a text prompt or a video, plus locomotion, looping and auto-rigging, with Blender and Maya plugins. You pay per second of motion. Free-plan output stays Uthana's and is licensed CC BY 4.0, so you can ship it with a credit line, or pay to own it outright.

Best for Voiced realtime NPC dialogue

Can you ship it?

Yes, free tier Pricing table lists a commercial license on every plan, including free On-Demand Source

Price

On-Demand free (pay as you go, TTS from $25 per 1M chars). Creator $25/mo

Works with

REST, WebSocket, WebRTC APIs; Node.js and Python SDKs

Inworld now offers voices, speech-to-text, a model router and realtime speech-to-speech that you wire into NPCs over REST, WebSocket or WebRTC. It lists Unreal and Unity as targets, but the catch is that integration goes through APIs with Node.js and Python SDKs rather than a dedicated engine plugin, and costs scale with every character spoken.

Best for Free browser video mocap to FBX

Can you ship it?

Not confirmed yet We only fill this in from the maker's own terms. Check them before you ship.

Price

Starter free (30 sec/mo). Basic $10/mo billed yearly (600 sec/mo)

Works with

Exports FBX (BVH on paid plans)

Rokoko Vision turns video into an FBX animation right in your browser, and the free Starter plan gives you 30 seconds of processing a month to try it. Watch out: BVH export, cleanup tools and live streaming into Unreal, Unity or Blender sit on paid tiers, and the terms do not spell out commercial use of Vision output.

Best for Keeping generated art consistent with your game's style

Can you ship it?

Paid plan needed Any paid plan (from $15/mo). Free outputs are personal and evaluation use only. Source

Price

Starter $15/mo. Pro $45/mo for custom training

Works with

Exports PNG, GLB, FBX; API

Train a custom model on 10 to 30 of your own images and generate new assets in that style. Training needs the Pro plan. Paid plans include a commercial license; free outputs are for personal use only.

Best for High-quality image or text to 3D models

Can you ship it?

Paid plan needed Creator plan ($24/mo yearly) adds unlimited export and any-use rights Source

Price

Free (pay per result, $1.50/credit). Creator $30/mo or $24/mo billed yearly

Works with

Exports FBX, OBJ, GLB, GLTF, USDZ, STL; Blender, Unity, Unreal, Godot plugins

Rodin generates textured 3D models from text or images, with a Smart Low-Poly option and plugins for Blender, Unity, Unreal and Godot. You can preview before spending credits, but the catch is that the free tier does not include unlimited export or any-use rights, so commercial work needs Creator or above.

Best for Concept art, textures and 2D game assets

Can you ship it?

Paid plan needed Paid plans (from $12/mo) own outputs; free-tier outputs vest in Leonardo Source

Price

Free (150 tokens/day, public). Essential $12/mo

Works with

Exports images and video

Leonardo generates images and video for concept art, sprites and textures, with custom models you can train on your own style. Watch out: on the free plan your creations are public and the terms assign ownership of them to Leonardo, so pay for a plan before making art you plan to ship.

Best for Free local image to 3D mesh

Can you ship it?

Yes, with conditions Free under $1M annual revenue; above that you need an Enterprise License Source

Price

Free weights under Community License. API on platform.stability.ai

Works with

Outputs textured 3D mesh (self-hosted or API)

Stable Fast 3D turns a single image into a textured, UV-unwrapped low-poly mesh in under a second, and you can download the weights to run it yourself or call it through Stability's API. It ships under the Community License, which is free only while your annual revenue stays at or under $1M.

Best for Open-weight image to 3D with PBR materials

Can you ship it?

Depends, see note Not licensed in EU, UK or South Korea; over 1M MAU needs Tencent's approval Source

Price

Free open weights

Works with

Outputs 3D meshes with PBR textures (self-hosted)

Hunyuan3D 2.1 is an open-weight image to 3D model with PBR materials that you can run on your own GPU, and Tencent claims no rights in what you generate. The license is the catch: it does not apply in the EU, UK or South Korea, and products past 1M monthly active users need a separate license from Tencent.

Best for Voice lines, sound effects and music in one place

Can you ship it?

Paid plan needed Starter plan or higher includes the commercial license; Free has none. Source

Price

Free (no commercial use). Starter from $6/mo

Works with

Web, API

Paid plan needed Pro plan or higher for commercial rights; read Suno's terms for further limits. Source

Price

Free (no commercial rights). Pro $8/mo, or about $6/mo billed yearly

Works with

Exports MP3, MIDI (WAV on Pro)

AIVA composes full music tracks in a chosen style and lets you download MP3 and MIDI, so you can rework the score in your own DAW. Licensing is the catch: the free plan is non-commercial with credit required, and the mid tier only allows monetizing on YouTube, Twitch, TikTok and Instagram, so selling a game needs Pro.

Best for Royalty-free background music you can tweak per scene

Can you ship it?

Paid plan needed All paid plans cover commercial use, video games named; no free plan Source

Price

Creator $16.99/mo, or $11.04/mo billed yearly. Stems from Artist Pro $35.99/mo

Works with

Exports MP3 (WAV, stems on Artist Pro and up)

SOUNDRAW generates instrumental tracks you can edit by length and section, and its license explicitly covers video games on every plan. Watch out: there is no free tier, the cheapest plan only exports MP3, and you need a higher Artist plan for WAV and stems.

Best for Sound effects and loops, hosted or self-hosted

Can you ship it?

Yes, with conditions You own the output; free to sell under $1M a year in revenue, Enterprise above Source

Price

App from $12/mo (Solo, 660 credits). Open weights free under $1M revenue

Works with

Web app, API, self-hosted open weights

Stable Audio generates music and sound effects from text prompts, with a web app, an API, and open-weight models you can run yourself. The license is tied to company size. Once your studio passes $1M in annual revenue you need a paid Enterprise license.

Works with

Windows, macOS desktop app

Krotos Studio is a desktop app where you shape footsteps, whooshes and ambiences from its sound library with AI-assisted presets and an AI ambience generator, rather than pure generative audio. One catch: the base Studio tier excludes video games; you need Studio Pro or higher to ship sounds in a game.

Price

Free 60 credits/mo (watermark). Starter $15/mo

Price

Free (1 media hr/mo, 720p, watermark). Hobbyist $16/mo billed yearly, $24 monthly

Works with

Web, Windows, macOS

Descript turns your recording into a text transcript you edit like a document, and its AI tools can cut social clips from longer devlogs. Watch out: the free plan exports at 720p with a watermark, and the AI tools are limited until you pay.

Can you ship it?

Nothing to ship Promo video only; Kapwing says AI exports can be used commercially Source

Price

Free (720p, watermark, 10 credits). Pro $16/mo, Business $50/mo

Works with

Web

Kapwing is a browser video editor whose AI assistant can pull highlights from long videos, resize them for TikTok or Shorts, and add subtitles. The catch: the free plan caps videos at 4 minutes and 720p with a watermark, and there is no free trial of paid plans.

Can you ship it?

Paid plan needed Free is for gamers; pro creators and orgs must contact sales to subscribe Source

Price

Free (1080p with Powder outro). Pro $9.99/mo, 20% off yearly

Price

Starter $12/mo billed yearly, $19 monthly. Pro $23/mo yearly

Works with

Web, API

Submagic adds styled auto captions to short videos, and higher tiers add auto zoom, silence and bad-take removal, and social publishing. Watch out: the cheapest plan only handles videos up to 2 minutes and about 15 videos a month, and the useful editing extras start at Pro.

Price
