Lovable Prompt

Lovable Ready

1Build PromptLedger, a web app for managing production prompts like code. Users create a prompt with a name, purpose, variables and content, and every save creates a new version with a diff against the previous one. Each prompt has a test set of sample inputs and expected qualities, and a run view where the user records or generates outputs per version so versions can be compared side by side. Include an environment toggle to mark which version is live, one-click rollback, comments on versions, and a team library with tags and search. Use authentication with team roles, a database for prompts, versions, test cases and runs, and an AI model for generating outputs against a version. Design it clean and technical with diffs, monospace content and a light theme.
