SeeleAgent
SeeleAgent by Seele AI is an AI game generator and multimodal creation agent. From a single text or image prompt it builds playable 2D and 3D games, 3D models, textures, rigs, audio, video, and project code, then lets you playtest in the browser and export the project to Unity, Unreal Engine, or Three.js. A Seele REST API is also available.
What is SeeleAgent?
SeeleAgent is Seele AI's multimodal creation agent and AI game generator, described by its maker as "the first game-native harness agent." Rather than returning isolated assets or code snippets, it accepts one natural-language prompt or an uploaded image and produces a complete, playable first build that runs directly in the browser.
Behind the agent are Seele AI's in-house foundation models. Seele02 is a native multimodal foundation model with a Mixture-of-Transformers architecture that unifies text, 3D, and spatial understanding, generation, and multi-turn editing, and it is tool-call ready as a general agent base. eva01 treats mesh as a native language, understanding objects and generating geometry without losing identity across long context. The Seele PEGA Worldmodel is a world model with long-term 3D context memory that predicts how game worlds evolve over time with spatial consistency.
SeeleAgent ships with a library of skills covering each modality: one-prompt game generation, Unreal FPS/TPS shooters, voxel and 3D FPS starters, dungeon roguelikes, level generators, 3D asset editing and optimization, game art, video, UGC ads, and animation. Users can invoke a single skill and the agent runs it end to end, or teach the agent new skills. Output targets three engines: Three.js for web, Unity 6, and Unreal, where Seele markets the world's first online native Unreal workflow with browser preview, packaging, and download.
Beyond games, the same workspace generates images such as concept art, sprites, UI designs, and posters, cinematic video, 3D models with textures, rigs, and animations, marketing assets, and full web pages. It can wire in Stripe, PayPal, and Alipay checkout plus ad networks, and it reports first place on two public Godot game-development benchmarks, GameCraft-Bench and GameDevBench, scored by hidden validation scripts with public result pages. The Seele API packages the pipeline as an asynchronous REST service, with an Agent Skill repository that teaches coding agents the workflow and delivers artifacts plus a shareable sandbox link.

Who is SeeleAgent for?
SeeleAgent suits anyone who has a game idea and wants to see it playable before committing months of production time. Non-coders and first-time creators are a primary audience: Seele explicitly designs for non-technical makers, and the vibe-coding workflow means you describe a game in plain language while the agent handles logic, assets, and integration. Indie developers use it to prototype mechanics, block out levels, and generate placeholder art, then export an editable project and continue in Unity 6 or Unreal. Studios point to it for rapid pre-production, concept art, design documents, economy balancing, difficulty tuning, and worldbuilding. Solo creators and remix artists can take an existing community game, swap characters or rules, and publish their own version. Educators and students get a zero-setup path to teaching game logic and 3D thinking without installing an engine, which the site calls out through its education and creator programs. Modders and hobbyists benefit from the asset generation, rigging, and optimization skills. Marketing and community teams use the same agent for trailers, UGC-style ads, promo images, and landing pages, since the workspace generates that material too. Product teams that want game generation inside their own software are served by the Seele API, which supports integration from Claude Code, Codex, OpenClaw, or any agent runtime that can call tools. Larger organizations can look at the enterprise tier, private cloud host, and publishing support. Because the free tier supplies credits without a credit card, trying the whole pipeline costs nothing but time.

SeeleAgent Pros and Cons
Pros
- Full production pipeline in one workspace: games, art, 3D, video, code, and web from a single agent
- Free tier with credits and no credit card required to start building, playing, and sharing
- Rare export breadth, covering Three.js, Unity 6, and native Unreal workflows from a prompt
- Public REST API plus an Agent Skill repo that plugs into Claude Code, Codex, and similar tools
- Published first-place benchmark results on GameCraft-Bench and GameDevBench with verifiable pages
Cons
- Generation is asynchronous and can take minutes to tens of minutes depending on model tier and complexity
- The API is task-based and is not compatible with the OpenAI chat completions protocol
- Commercial use rights and artifact downloads require a paid plan, so free-tier output is deliberately limited
FAQ About SeeleAgent
SeeleAgent Pricing
SeeleAgent is free to start: the free tier provides credits to build, play, and share games, images, video, 3D assets, and code, and no credit card is required. Paid subscriptions are billed monthly with an annual option saving 22 percent, and usage is metered in Koins, the platform compute unit deducted dynamically by task complexity. As listed on the pricing pages, Standard is about $20 per month with 2,000 Koins, Pro about $50 per month with 5,000 to 6,000 Koins, and Ultra $200 per month with 25,000 to 40,000 Koins; unused Koins roll over. One-time Koin Packs top up balances, new users are offered 50 percent off the first month, and an Enterprise tier is listed. Subscriptions include a 7-day trial and 7-day money-back terms.
