How it works
A calm workflow, not a portal of competing tools.
The first release keeps one primary action per screen and separates creation, checking, and learning.
Generate locally
Rule-based builders create detailed, compact, and reusable forms without contacting an AI provider.
Review the structure
Use the checker to identify missing structural cues, then run the final prompt in your own AI.

After
