Copy CSS from any website and turn designs, images or prompts into clean front-end code
A browser extension extracts clean HTML and CSS from any element on a live page and converts it into Tailwind, React, or your chosen framework.
Upload a UI design or screenshot and get responsive, structured front-end code back in seconds.
Generate production-ready React components or complete HTML pages and email templates from text prompts, with Tailwind, Bootstrap, or vanilla CSS support.
Refine generated components conversationally and preview edits in real time inside an interactive code editor.
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.
