Spawnly
88+What happens after you press Enter
This is one real request, “make me a wooden park bench”, on Gemini 3.8 Flash. It took 34 seconds and 2 credits, and the panel showed each step as it happened.
It reads your place
Objects, scripts, what is where. It starts from what exists rather than guessing.
It searches the Creator Store
Benches are something people have already made well. It picks a free model with good votes and no scripts of its own.
It places the bench where you are looking
Sized to three studs, anchored, on the floor rather than on the chair you happened to aim at.
It checks its own work
Nothing floating, nothing sunk, nothing left loose. If something is off it fixes it before saying a word.
It tells you, in plain words
What it inserted, who made it, where it is, and three ideas for what to do next.
Built to live next to your Explorer
Chats, per place
Every place keeps its own chats and folders. Open a place and its history is there.
Credits in the header
The counter shows what you have. A finished request shows what it used.
Revert on every script edit
Under Changes, each edited script has a Revert button. Everything else undoes with Ctrl+Z.
Five models. Pick one per message.
| Model | Good for | Power | Price |
|---|---|---|---|
 DeepSeek V4 Flash | Cheapest. Quick edits and questions. | ||
 Gemini 3.8 Flash | Fast everyday all-rounder. | ||
 Claude SonnetDefault | Systems, UI, fixes. | ||
 GPT-5.4 | Big features, tricky bugs. | ||
| Claude Opus | Whole games, hardest bugs. |
Power is the model's class, from its maker. Price is from its list price. Nothing is a score we invented. More about each model
Pay for what it does
No subscription. Each request costs credits according to the model it used and how much it had to read and do: a question is 1 or 2, a shop with a working purchase around 10, a whole system up to 40.
