From a plain-language brief to a working, multi-role Next.js product
Enter a brief in plain language and Jbox generates the screens, roles, navigation and logic that make up a working product, not just static mockups.
Before any code is written, Jbox lays out every role, screen, decision and handoff as one visible map so missing paths and edge cases surface early.
Builds ship as Next.js, TypeScript, Tailwind and shadcn/ui projects with Supabase backend, authentication and row-level security wiring.
Generated projects can be exported to GitHub and hosted on your own infrastructure or on Jbox Hosting, so you are never locked in to a prototype.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
