Prompt Lab
Compose · Expand · ShipTurn one idea into rich JSON image prompts
The full studio, admin-side — every craft control (lighting, camera, lens, detail, creativity) streamed into structured JSON prompts. Copy any view, edit, regenerate, then push one straight through the expansion below to see exactly what the model receives.
Every prompt, quietly rewritten
What tells the editor how to rewrite
This house-style note is appended to the built-in craft that rewrites every short prompt before it reaches the image model. Saved changes apply to the very next generation — no restart.
These shape the JSON the editor returns, before the note above is applied. They were fixed in code until now. Saved changes apply to the very next generation — no restart.
See it working in production
The last renders — what the user typed, what Saga actually sent, and whether the expansion held or fell back to the raw prompt.
The craft learns from production
Each pass reads the recent renders above — what was typed, what was sent, what failed, and which prompts users kept re-running — and proposes a revised instruction with its reasoning. Applying is one click and so is rolling it back; the previous instruction is kept on every proposal. Auto-analyze runs a pass every few hours once there's enough new material; auto-apply additionally ships high-confidence revisions without waiting for you.
