Prompt starter
Give the team one brief with the player objective, camera, movement rules, and the part of the level to prototype.
Level Blockout AI Generator
Plan the route before you build the art. Turn a level idea into a graybox brief with routes, rough dimensions, and playtest checks. Continue with your prompt in Workspace.

How it works
From level brief to playtest plan
- 01 · Step 1
Define the player goal
Name the genre, camera, target platform, and movement limits. Mark where players start, what they need to do, and where the level ends.
- 02 · Step 2
Compare routes
Keep the goal fixed and vary the route, sightlines, or elevation. Record how each version changes pacing and what geometry it needs.
- 03 · Step 3
Prepare the graybox review
Pick a layout, list the primitive shapes you need, and bring the brief into Workspace with a short checklist for the first playtest.
Pick a starting point
Start with a level blockout prompt
First pass for a rooftop route
Plan a short route that teaches one jump before asking the player to cross a wider gap.
Prompt
Graybox a rooftop platformer with two practice jumps, a checkpoint, and a final jump to the exit. Size each gap against the maximum jump distance and add a landing check.
- Safe place to learn the jump
- Reachable gaps
- Clear checkpoint and exit
Why SEELE
What goes into a level blockout brief
Layout variants and production notes
Compare routes against the same goal. Record rough sizes, placeholder geometry, and assumptions so the team can choose what to build first.
Playtest checklist
Check navigation, pacing, and gameplay feel in the graybox. Review originality, asset rights, accessibility, and performance before publishing.
FAQ
Frequently asked questions
What is a level blockout?
A level blockout, also called a graybox, uses simple shapes to test the size, route, and pacing of a game level before detailed art is added.
What does the AI Level Blockout Generator help me make?
It helps turn a level idea into a prompt, a production brief, layout variants, and review notes you can refine in Workspace.
How do I start from a short prompt?
Name the genre, player goal, camera, target platform, and any movement or production constraints. Pick a starter or write your own, then continue in Workspace.
What should the first brief include?
Include a scoped concept, the start and exit, key routes, placeholder geometry, and a checklist of what the first playtest needs to answer.
How can I compare two layouts fairly?
Keep the player goal and movement rules fixed. Change one part of the layout at a time and compare route length, sightlines, and places where players get stuck.
What still needs human review?
Playtest the layout for gameplay feel, balance, and accessibility. Review originality, brand fit, asset rights, and performance before publishing.
