About

Stele is a browser-based UI reference library for frontend developers, design engineers, and designers who work with code. Its Chrome extension captures web-page elements, full pages, screenshots, video, bookmarks, code, and notes in a searchable visual workspace. Captures retain HTML, styles, assets, and design tokens, allowing users to inspect colors, fonts, spacing, and component details after saving. The web app provides semantic search, tagging, accessibility and contrast checks, and exports to React, HTML, and Tailwind. Users can connect AI coding tools through Model Context Protocol (MCP) to search and use saved references as context, and import inspiration from services including Pinterest, Dribbble, Behance, X, and Raindrop.io. Stele offers a free plan and a paid Pro subscription.

About

Supernova is the agentic design system platform for AI-first product teams. We centralize the design and engineering knowledge behind a product — tokens, components, rules, code patterns, files, and skills — and turn it into connected intelligence that any AI agent can use to build correctly and consistently. Supernova agents also handle the ongoing maintenance: when design data changes, when a pull request lands, or when feedback comes in, our agents pick up the task and finish it automatically. Through an MCP server, that knowledge becomes something AI coding & design tools and agents can query directly — so instead of guessing at styles from scratch, they generate UI that's on-brand, accessible, and consistent with production code from the first prompt.
