Prompt to Spine animation

How do I make a Spine animation from a text prompt?

1. Open the app and choose Symbols or Characters. Prompts make symbols, objects and characters.
2. Choose the animations you need from the templates, for example idle, land and win.
3. Choose “Describe it” and write a prompt of up to 400 characters, for example “a golden treasure chest with rubies”.
4. Pick one of 5 picture variants. Choosing is free. If none fits, ask for 5 new variants.
5. Animate. The AI places the bones, builds the weighted mesh and plays the templates you chose. This is done for you on our servers.
6. Preview and download. The animation plays in the browser with the official Spine runtime 4.2. Download the zip when you are happy with it.

What do I get from a prompt?

A Spine 4.2 export in one zip:

• skeleton.json: the Spine 4.2 skeleton data with bones, weighted meshes and the animations you chose.
• skeleton.atlas: the texture atlas description.
• The PNG texture pages, straight alpha.
• A README file.

Each template you picked becomes a named animation in the file. Idle loops are loop-perfect, and win returns to the first frame of idle, so the two chain without a jump.

Which animations can a prompt object get?

There are two template lists. Game symbols: idle land win dissolve anticipation. Props and pickups: appear open open_idle collect explode press hit.

One animation job uses one of the two lists; idle is in both. Templates are proven motion sets with fixed timing, loop-perfect idles and clean returns to the first frame, so the result is predictable and the price is fixed.

Can I change the animation with words?

Yes. After a symbol or object animation is built, describe a change in your own words, for example “jump higher, no spin”, “slower and smoother” or “make all effects gold”. You can change the motion, speed, timing, effects and colours. New objects cannot be added yet.

Each text edit costs 5 tokens. Templates are guaranteed; custom edits are best-effort.

How much does prompt to Spine cost?

One object from a prompt costs 30 tokens: 5 picture variants to choose from, then the animation from a template, with the Spine 4.2 export included. 5 new picture variants cost 5 tokens. A text edit costs 5 tokens. One character from a prompt costs 70 tokens and gets an idle loop.

Tokens come with a monthly plan: Indie $19 a month for 300 tokens, Studio $59 a month for 1200 tokens, Pro $199 a month for 5000 tokens. Yearly billing costs $190, $590 and $1,990 a year. Subscribers can add one-time top-ups from $9 for 100 tokens; top-ups need an active plan. There is no free trial and there are no free tokens. Payments are by card through Stripe, sold through Link. All purchases are final, see the Refund Policy; if an animation fails on our side, its tokens are returned automatically.

What are the limits?

• A character from a prompt gets an idle loop today; a win animation for characters is coming soon.
• The export is Spine 4.2 data, not a .spine editor project.
• You need your own Spine licence to use the Spine editor or a Spine runtime in your product.
• Text edits cannot add new objects yet, and edit quality is not guaranteed.
• Animate4Me is an AI tool and results may vary.
