The engine filter shows tools whose vendor states a plugin, integration or export for that engine. Most other tools export standard files (PNG, FBX, GLB, WAV and so on) that work in any engine.
AI composer for soundtrack-style music with MIDI and audio export, editable in its built-in editor.
Verdict: For soundtrack-style game music; only the Pro plan gives you the copyright, and the free plan is non-commercial.
AI background-music generator; its site lists games among supported uses.
Verdict: For background music you can monetise; you get a perpetual licence but Beatoven keeps ownership, and pricing is unverified.
Physics-based keyframe animation software with AI-assisted autoposing, inbetweening and mocap cleanup; exports FBX, DAE, USD and glTF on paid plans.
Verdict: For hand-keyed character animation with AI posing help; free is non-commercial, and Indie only covers studios under $100k a year in revenue/funding.
Platform for building interactive stories and AI character conversations, with script flow tools and AI voices, published to web, VR or game engines via SDKs.
Verdict: For story-driven AI character conversations on pay-as-you-go credits; its terms assign input and output rights to the customer.
Conversational AI characters for games and virtual worlds: NPCs with voice, knowledge and actions.
Verdict: For conversational NPCs with a free tier to prototype on; its terms give you ownership of AI-generated content.
AI-first code editor with agents, chat and codebase-aware edits; usable for gameplay code in any language or engine.
Verdict: For devs who want an AI-first editor with a free tier; its terms assign suggestion rights to you, and third-party model usage is billed separately.
Markerless AI motion capture: turns ordinary video into 3D character animation; sister product SayMotion does text-to-motion.
Verdict: For turning reference video into 3D animation cheaply; the free Freemium tier is non-commercial only.
Text-to-speech, voices, sound effects and music generation; usable for NPC voice lines and SFX.
Verdict: For NPC voice lines and SFX; free-plan output is non-commercial, so a paid plan is required to ship.
AI coding assistant with code completions, chat and agent mode; usable for gameplay code in any engine's scripting language.
Verdict: For coding in any engine with a free starting tier; GitHub says it doesn't own suggestions, and IP indemnity only comes with organization plans.
Open-weights image-to-3D model with PBR material generation that you can run on your own hardware.
Verdict: For devs who can self-host a 3D model generator at no licence cost; the licence excludes the EU, UK and South Korea, and products over 1 million monthly users must request a licence.
Rodin generates 3D models from text or images, with options like high-poly quad meshes; the platform also lists HDRI and texture generators.
Verdict: For high-detail 3D generation; commercial rights on the Free and Creator tiers are unverified, so check its terms before you ship.
Realtime text-to-speech and LLM inference platform that can power voiced, interactive characters.
Verdict: For realtime TTS and LLM-driven characters on pay-as-you-go pricing; its terms assign outputs to you.
Generative content platform aimed at game studios: style-trained models, concept art, marketing creatives and asset variations with team workflows.

General image and video generation platform with trainable custom models; usable for concept art, item icons and texture ideas.
Verdict: For general concept art and icon ideas; free-tier output can be used commercially but is public and Leonardo holds rights to it, while paid plans give you ownership.
Game ideation and asset tool: concept generation, sprites and sprite sheets, textures, plus a Unity editor plugin and API.
Verdict: For Unity devs who want ideation and 2D assets in one place; its FAQ says you own what you generate, but free-plan sprite sheets are watermarked.
AI toolkit that runs inside the Unreal Engine editor: an agent that understands your project's Blueprints, C++, assets and levels and can answer questions and make edits.
Verdict: For Unreal devs who want a project-aware assistant in the editor; it has no free credits beyond a 14-day trial, and its output licence is unverified.
Text-to-3D and image-to-3D model generation with AI texturing; paid plans add animation with 600+ motions. DCC bridge listed for Roblox, Blender, Godot, Unity and Unreal.
Verdict: For quick text- or image-to-3D props with Godot/Unity/Unreal bridges; free output is CC BY 4.0, so you must credit Meshy unless you pay.
AI-generated royalty-free music tracks by mood, genre and duration, with a track editor.
Verdict: For royalty-free background tracks; game use points to the Business plan, and tracks can't be redistributed as standalone music.
AI generator for pixel art game assets: characters, 4/8-direction rotations, text- and skeleton-based sprite animations, tilesets, maps and UI elements.
Verdict: For 2D devs who need pixel-art sprites, rotations and animations; outputs are usable commercially on every plan, but its terms bar training other models on them.

Verdict: For studios that want custom style models trained on their own art; commercial use needs a paid plan (free output is personal/evaluation only).
Generates 360° panoramic skyboxes and environments (up to 16K and HDRI on higher tiers), with an API for in-app generation.
Verdict: For 360° skyboxes and environment backdrops; the terms say you own your assets, but commercial terms below the Business tier are unverified.

Verdict: For 3D models with retopology and engine bridges; the free plan is non-commercial, so shipping assets requires a paid plan.
AI music generation and remixing app.
Verdict: For personal music experiments only; its current terms prohibit commercial use of output, so it isn't suitable for shipped games.
AI built into the Unity Editor: an Assistant for project questions and code, plus generators for images, textures, materials, sounds, 3D models and animations, metered in Unity Credits.
Verdict: For Unity users who want AI inside the editor, with monthly credits included on Personal, Pro and Enterprise plans; AI-output licence terms are unverified.
