Start free. Create more.

Yes. The Free plan needs no credit card and gives you one project and 5 credits each month with GPT-6 Luna. Those credits also cover one thumbnail a month. You can stay on Free for as long as you like, and upgrade to Creator when you want unlimited projects, more credits, DeepSeek V4 Flash and the image, 3D and sound tools.

Build messages start at 1 credit with GPT-6 Luna or DeepSeek V4 Flash. Larger requests can use more. Set a message limit to cap the charge; each reply shows the credits used, and unused reserved credits return to your balance.

Paid subscription credits refresh when your subscription renews. Free credits refresh at the start of each calendar month in UTC. Monthly credits do not roll over. Purchased credit packs never expire and are used once your monthly credits run out.

Yes, on every plan. Connect your ChatGPT Plus, Pro or Business plan from the credits card: you turn on device code authorization in ChatGPT's security settings, enter a short code, and from then on GPT-6 Luna builds run on your plan and use no Trampoline credits, within ChatGPT's own usage limits. DeepSeek builds and the thumbnail, sound and 3D tools keep using credits, so on Creator your credits become the budget for assets. You can switch back to credits at any time.

The Thumbnail Generator is included on every plan. Only Creator includes AI image generation and editing, 3D asset generation, and sound effects and loops. They all use the same monthly credits as coding: a 16:9 thumbnail from the Thumbnail Generator is 3 credits, a concept image is 2, turning it into a 3D model is 15, and a sound effect is 3, 8 or 10 credits for 2, 5 or 10 seconds, shown before you generate. Previewing and downloading saved assets does not use generation credits. Generated models and sounds go straight into your open Studio place with Use in game, and models also download as FBX.

No. Packs work on every plan, including Free, and their credits never expire. Your plan still decides which tools you can use. Packs do not unlock Creator asset generation or increase your plan’s AI processing allowance. If that allowance is exhausted, you must wait for its reset even if you have credits left.

Unlimited projects does not mean unlimited AI generation. Every plan has a credit allowance and a separate AI processing allowance; Creator’s processing ceiling is $5.00 per subscription period across coding, planning and assets. Provider work can count toward that ceiling even when generation credits are refunded. Generation pauses when either limit is reached, with no automatic overage charge. See our Fair Use Policy for limits and acceptable use.

Start by describing what you want in plain English. Trampoline generates the Luau and works with its Studio plugin to apply changes to your place. You can inspect the code and keep refining it through chat.

Yes. Roblox Studio is where your game runs. Download the Trampoline plugin, open your place in Studio, and connect it to the builder to see your ideas come to life.

Paid plans are monthly subscriptions and credit packs are one-time payments, both billed by Stripe. Card details never touch our servers. You can update your card, switch plans or cancel anytime from the billing portal; a cancelled plan stays active until the end of the period you paid for.
