✓ Pricing re-verified 2 Oct 2026
Everything is paid for in Koins, the platform's credit, deducted per task according to the model, cloud time and third-party tools used, so there is no fixed price per game. A new account gets 360 Koins on sign-up, with no credit card. Standard is $20 a month for 2,000 Koins, Pro $50 for 6,000 and Ultra $200 for 25,000; billed annually they show as $17, $39 and $167 a month.
The toggle says annual saves 22%, which is true for Pro; on Standard it is 15% and on Ultra about 16%. Pro adds commercial use, 'advanced monetization', 20 instead of 10 parallel tasks and 50GB instead of 20GB of storage; Ultra adds 200GB, a private cloud host and publishing support. Koin Packs without a plan cost $20 for 2,000, $50 for 5,000, $200 for 20,000 and $500 for 50,000, and do not include plan benefits such as the advanced models, asset downloads or the priority queue.
The upgrade page applied a 'New User 50% Off First Month' coupon by default. Payment by card through Stripe. The terms name SEELE AI, Inc. and the usage policy SEELE Technology Limited. Plans change — always verify the live price on their site.

Koins are deducted by the AI time, cloud time and third-party tools a task uses, and the help centre says every change you ask for, from renaming a character to fixing a bug, is a new generation that costs Koins again. It also says Unity projects cost significantly more than lightweight Three.js web games. The 360 free Koins are meant for a first build, and one public review we read, from a 16-year-old, says he ran out before finishing his first game.
The cheapest plan does not let you sell what you make. Commercial use is listed on Pro and Ultra only, and the terms (section 4.2, updated 28 July 2026) say the right to publish, sell or advertise in your games comes with an active subscription at Pro or above, which is $50 a month or $39 billed annually. On Standard at $20 you can build and share, not earn. The pricing page and the terms disagree on the two things that protect your money.
The upgrade page FAQ says unused Koins roll over and the help centre says they never expire, while the terms say unused subscription Koins do not carry over to the next billing period. The upgrade page advertises a 7-day free trial and a 7-day money-back guarantee, while the terms say all payments are final and non-refundable, and that refunds may be refused for anything bought with a coupon or discount, which covers the 50% first-month offer the page applies by default.
The terms also say a chargeback raised without first emailing support will be treated as fraud. Finally, the homepage promises you can take your Unity project with you, while the help centre's article on Koins says source code download is currently not available. We have not used the product.
AI game-studio agent that turns a text prompt, image or drawing into a playable 2D or 3D game in the browser, with Three.js, Unity and Unreal targets and generated 3D assets, images, video and audio, billed in Koin credits.

Use the 360 free Koins to see how far one game gets you, and build it in Three.js first, since the help centre says web games use fewer Koins than Unity. If the game is for fun or for a class, Standard at $20 a month is enough; its 2,000 Koins are the same amount a $20 Koin Pack buys, but the plan also gives you the better model, asset downloads and priority queue that a pack does not.
If you plan to put the game on a store, run ads in it or sell it, the terms make Pro the minimum: $50 a month, or $39 a month billed annually, which is the one plan where the advertised 22% annual saving is accurate. Ultra at $200 is for heavy users who need 25,000 Koins a month and publishing support. Think twice before taking the 50% first-month discount if a refund might matter to you, because the terms allow refunds to be refused on anything bought with a discount.
Sign up at seeles.ai with an email or Google account to receive the 360 sign-up Koins; no card is needed. Start a new workspace from one of the ready-made skills, such as a 2D or web game, rather than a blank prompt, and keep the first request small: every follow-up change costs Koins again, so describe the game fully up front instead of iterating line by line. Check the usage dashboard after each step to learn what a typical change costs.
If a generation fails because of a server error, email service@seeles.ai with a screenshot and the page address; the help centre says Koins for failed tasks are refunded to your balance after a manual check, but not for results you simply dislike. You can log in on only one device at a time. Before you subscribe, decide whether you will sell the game, because that decides between Standard and Pro, and keep a copy of the terms page from the day you pay, since it and the pricing page do not say the same thing about refunds and unused Koins. Cancel from your account settings; access continues to the end of the billing period.
Distilled from Seele's upgrade page on the monthly, annual and Koin Pack tabs, its homepage, workspace sign-up screen, terms of service (updated 28 July 2026), acceptable use policy and help-centre articles on Koin consumption, Koin refunds, membership refunds and cancellation, all read on 2 October 2026; the public reviews on Seele's Trustpilot page read the same day; and Rosebud AI's pricing page for the comparison. We have not used the product.
The natural comparison is Rosebud AI — Rosebud AI is the closest alternative: it also turns prompts into browser games and charges in credits. On its pricing page, read on 2 October 2026, Indie Dev is $15 a month, 10x Dev at $30 adds full commercial rights and removes Rosebud branding, Pro at $50 adds downloadable project code and Scale is $100; Rosebud says unused credits roll over once and then expire. So on Rosebud commercial rights cost $30 a month and code download is a listed feature at $50, while on Seele commercial use starts at $50 and code download is not available according to its own help centre. Seele's case is breadth: Unity and Unreal targets, 3D assets, video and audio generation in the same workspace. Pick Rosebud if you want to own and sell a web game at the lowest price; pick Seele if you want a 3D or Unity project and a single tool for the game and its assets..
Standard is $20 a month for 2,000 Koins, Pro $50 for 6,000 and Ultra $200 for 25,000, or $17, $39 and $167 a month billed annually. New accounts get 360 free Koins. Read on seeles.ai/upgrade on 2 October 2026.
Only on Pro or Ultra. The terms say commercial use of what you create requires an active subscription at Pro or above; the $20 Standard plan does not include it.
There is no fixed price. Koins are deducted by the AI time, cloud time and tools a task uses, every change is charged as a new generation, and Unity projects cost significantly more than Three.js web games, according to Seele's help centre.
Up to a point, and that point is usually set by your plan. Check whether brand kits, custom fonts, colour locking and template controls sit on the tier you would actually buy, since these are common upsells. Test it with your own assets during the trial rather than the demo content, which is always chosen to flatter the output.
