Design Rails

Design Rails is an AI-native brand identity platform that enables users to create complete brand packages through conversational chat with an AI designer. The tool generates logos, color palettes, typography systems, and code-ready specifications in under 10 minutes, making it ideal for builders, developers, and entrepreneurs who need professional branding without design experience. Backed by Y Combinator, it bridges the gap between brand design and AI-powered development workflows.

• Conversational Brand Creation allows users to describe their project, vibe, and vision while the AI asks clarifying questions and generates options for iterative refinement until the brand feels right.

• Complete Logo Package delivers primary logos, wordmarks, and icon-only versions in SVG and PNG formats with light, dark, and monochrome variants ready for apps, favicons, and marketing materials.

• Code-Ready Specifications provides structured files that AI coding tools like Cursor, Claude, v0, Bolt.dev, and Lovable can read to maintain brand consistency during development.

• Shareable Style Guide generates a beautiful, web-based brand book in HTML format that can be shared with designers, developers, or stakeholders without requiring additional software.

• Typography & Color System includes font pairings, scales, hierarchy rules, and accessibility-checked color palettes with primary, secondary, and accent colors.

• UI Guidelines covers buttons, cards, forms, borders, shadows, spacing rules, and voice/tone patterns for CTAs, empty states, errors, and microcopy.

• LLM-Ready Agent Instructions outputs structured markdown files specifically formatted for AI coding assistants to stay on-brand during vibe-coding sessions.
